+/**
+ * Describes how to combine multiple time series to provide a different view of
+ * the data.  Aggregation of time series is done in two steps. First, each time
+ * series in the set is _aligned_ to the same time interval boundaries, then the
+ * set of time series is optionally _reduced_ in number.
+ * Alignment consists of applying the `per_series_aligner` operation
+ * to each time series after its data has been divided into regular
+ * `alignment_period` time intervals. This process takes _all_ of the data
+ * points in an alignment period, applies a mathematical transformation such as
+ * averaging, minimum, maximum, delta, etc., and converts them into a single
+ * data point per period.
+ * Reduction is when the aligned and transformed time series can optionally be
+ * combined, reducing the number of time series through similar mathematical
+ * transformations. Reduction involves applying a `cross_series_reducer` to
+ * all the time series, optionally sorting the time series into subsets with
+ * `group_by_fields`, and applying the reducer to each subset.
+ * The raw time series data can contain a huge amount of information from
+ * multiple sources. Alignment and reduction transforms this mass of data into
+ * a more manageable and representative collection of data, for example "the
+ * 95% latency across the average of all tasks in a cluster". This
+ * representative data can be more easily graphed and comprehended, and the
+ * individual time series data is still available for later drilldown. For more
+ * details, see [Filtering and
+ * aggregation](https://cloud.google.com/monitoring/api/v3/aggregation).

+/**
+ * The description of a dynamic collection of monitored resources. Each group
+ * has a filter that is matched against monitored resources and their associated
+ * metadata. If a group's filter matches an available monitored resource, then
+ * that resource is a member of that group.  Groups can contain any number of
+ * monitored resources, and each monitored resource can be a member of any
+ * number of groups.
+ * Groups can be nested in parent-child hierarchies. The `parentName` field
+ * identifies an optional parent for each group.  If a group has a parent, then
+ * the only monitored resources available to be matched by the group's filter
+ * are the resources contained in the parent group.  In other words, a group
+ * contains the monitored resources that match its filter and the filters of all
+ * the group's ancestors.  A group without a parent can contain any monitored
+ * resource.
+ * For example, consider an infrastructure running a set of instances with two
+ * user-defined tags: `"environment"` and `"role"`. A parent group has a filter,
+ * `environment="production"`.  A child of that parent group has a filter,
+ * `role="transcoder"`.  The parent group contains all instances in the
+ * production environment, regardless of their roles.  The child group contains
+ * instances that have the transcoder role *and* are in the production
+ * environment.
+ * The monitored resources contained in a group can change at any moment,
+ * depending on what resources exist and what filters are associated with the
+ * group and its ancestors.

+ *       measurements. The end time of a new interval must be at least a
+ *       millisecond after the end time of the previous interval.

+ * Service Description: The AlertPolicyService API is used to manage (list, create, delete,

+ * a description of the conditions under which some aspect of your
+ * system is considered to be "unhealthy" and the ways to notify
+ * people or services about this state. In addition to using this API, alert
+ * policies can also be managed through
+ * [Cloud Monitoring](https://cloud.google.com/monitoring/docs/),
+ * which can be reached by clicking the "Monitoring" tab in
+ * [Cloud console](https://console.cloud.google.com/).
+ *
+ * This class provides the ability to make remote calls to the backing service through method
+ * calls that map to API methods.
+ *
+ * Many parameters require resource names to be formatted in a particular way. To
+ * assist with these names, this class includes a format method for each type of
+ * name, and additionally a parseName method to extract the individual identifiers
+ * contained within formatted names that are returned by the API.

+/**
+ * Service Description: The Group API lets you inspect and manage your
+ * [groups](#google.monitoring.v3.Group).
+ *
+ * A group is a named filter that is used to identify
+ * a collection of monitored resources. Groups are typically used to
+ * mirror the physical and/or logical topology of the environment.
+ * Because group membership is computed dynamically, monitored
+ * resources that are started in the future are automatically placed
+ * in matching groups. By using a group to name monitored resources in,
+ * for example, an alert policy, the target of that alert policy is
+ * updated automatically as monitored resources are added and removed
+ * from the infrastructure.
+ *
+ * This class provides the ability to make remote calls to the backing service through method
+ * calls that map to API methods.

+ * the `Service`'s monitored resources, its Service-Level Objectives, and a
+ * taxonomy of categorized Health Metrics.
+ *
+ * This class provides the ability to make remote calls to the backing service through method
+ * calls that map to API methods.
+ *
+ * Many parameters require resource names to be formatted in a particular way. To
+ * assist with these names, this class includes a format method for each type of
+ * name, and additionally a parseName method to extract the individual identifiers
+ * contained within formatted names that are returned by the API.

+/**
+ * Service Description: The UptimeCheckService API is used to manage (list, create, delete, edit)
+ * Uptime check configurations in the Cloud Monitoring product. An Uptime
+ * check is a piece of configuration that determines which resources and
+ * services to monitor for availability. These configurations can also be
+ * configured interactively by navigating to the [Cloud console]
+ * (https://console.cloud.google.com), selecting the appropriate project,
+ * clicking on "Monitoring" on the left-hand side to navigate to Cloud
+ * Monitoring, and then clicking on "Uptime".
+ *
+ * This class provides the ability to make remote calls to the backing service through method
+ * calls that map to API methods.
+ *
+ * Many parameters require resource names to be formatted in a particular way. To
+ * assist with these names, this class includes a format method for each type of
+ * name, and additionally a parseName method to extract the individual identifiers
+ * contained within formatted names that are returned by the API.
+ *

+/**
+ * Service Description: The AlertPolicyService API is used to manage (list, create, delete,
+ * edit) alert policies in Cloud Monitoring. An alerting policy is
+ * a description of the conditions under which some aspect of your
+ * system is considered to be "unhealthy" and the ways to notify
+ * people or services about this state. In addition to using this API, alert
+ * policies can also be managed through
+ * [Cloud Monitoring](https://cloud.google.com/monitoring/docs/),
+ * which can be reached by clicking the "Monitoring" tab in
+ * [Cloud console](https://console.cloud.google.com/).
+ *
+ * This class provides the ability to make remote calls to the backing service through method
+ * calls that map to API methods. Sample code to get started:
+ *
+ * ```
+ * $alertPolicyServiceClient = new AlertPolicyServiceClient();
+ * try {
+ *     $name = 'name';
+ *     $alertPolicy = new AlertPolicy();
+ *     $response = $alertPolicyServiceClient->createAlertPolicy($name, $alertPolicy);
+ * } finally {
+ *     $alertPolicyServiceClient->close();
+ * }
+ * ```
+ *
+ * Many parameters require resource names to be formatted in a particular way. To
+ * assist with these names, this class includes a format method for each type of
+ * name, and additionally a parseName method to extract the individual identifiers
+ * contained within formatted names that are returned by the API.
+ *
+ * @deprecated Please use the new service client {@see \Google\Cloud\Monitoring\V3\Client\AlertPolicyServiceClient}.

+/**
+ * Service Description: The Group API lets you inspect and manage your
+ * [groups](#google.monitoring.v3.Group).
+ *
+ * A group is a named filter that is used to identify
+ * a collection of monitored resources. Groups are typically used to
+ * mirror the physical and/or logical topology of the environment.
+ * Because group membership is computed dynamically, monitored
+ * resources that are started in the future are automatically placed
+ * in matching groups. By using a group to name monitored resources in,
+ * for example, an alert policy, the target of that alert policy is
+ * updated automatically as monitored resources are added and removed
+ * from the infrastructure.
+ *
+ * This class provides the ability to make remote calls to the backing service through method
+ * calls that map to API methods. Sample code to get started:
+ *
+ * ```
+ * $groupServiceClient = new GroupServiceClient();
+ * try {
+ *     $name = 'name';
+ *     $group = new Group();
+ *     $response = $groupServiceClient->createGroup($name, $group);
+ * } finally {
+ *     $groupServiceClient->close();
+ * }
+ * ```
+ *
+ * Many parameters require resource names to be formatted in a particular way. To
+ * assist with these names, this class includes a format method for each type of
+ * name, and additionally a parseName method to extract the individual identifiers
+ * contained within formatted names that are returned by the API.
+ *
+ * @deprecated Please use the new service client {@see \Google\Cloud\Monitoring\V3\Client\GroupServiceClient}.

+ * ```
+ *
+ * Many parameters require resource names to be formatted in a particular way. To
+ * assist with these names, this class includes a format method for each type of
+ * name, and additionally a parseName method to extract the individual identifiers

+/**
+ * Service Description: The Notification Channel API provides access to configuration that
+ * controls how messages related to incidents are sent.
+ *
+ * This class provides the ability to make remote calls to the backing service through method
+ * calls that map to API methods. Sample code to get started:
+ *
+ * ```
+ * $notificationChannelServiceClient = new NotificationChannelServiceClient();
+ * try {
+ *     $name = 'name';
+ *     $notificationChannel = new NotificationChannel();
+ *     $response = $notificationChannelServiceClient->createNotificationChannel($name, $notificationChannel);
+ * } finally {
+ *     $notificationChannelServiceClient->close();
+ * }
+ * ```
+ *
+ * Many parameters require resource names to be formatted in a particular way. To
+ * assist with these names, this class includes a format method for each type of
+ * name, and additionally a parseName method to extract the individual identifiers
+ * contained within formatted names that are returned by the API.
+ *
+ * @deprecated Please use the new service client {@see \Google\Cloud\Monitoring\V3\Client\NotificationChannelServiceClient}.

+/**
+ * Service Description: The Cloud Monitoring Service-Oriented Monitoring API has endpoints for
+ * managing and querying aspects of a Metrics Scope's services. These include
+ * the `Service`'s monitored resources, its Service-Level Objectives, and a
+ * taxonomy of categorized Health Metrics.
+ *
+ * This class provides the ability to make remote calls to the backing service through method
+ * calls that map to API methods. Sample code to get started:
+ *
+ * ```
+ * $serviceMonitoringServiceClient = new ServiceMonitoringServiceClient();
+ * try {
+ *     $parent = 'parent';
+ *     $service = new Service();
+ *     $response = $serviceMonitoringServiceClient->createService($parent, $service);
+ * } finally {
+ *     $serviceMonitoringServiceClient->close();
+ * }
+ * ```
+ *
+ * Many parameters require resource names to be formatted in a particular way. To
+ * assist with these names, this class includes a format method for each type of
+ * name, and additionally a parseName method to extract the individual identifiers
+ * contained within formatted names that are returned by the API.
+ *
+ * @deprecated Please use the new service client {@see \Google\Cloud\Monitoring\V3\Client\ServiceMonitoringServiceClient}.

+     *
+     *           To filter on a particular service-identifier type, the `identifier_case`
+     *           refers to which option in the `identifier` field is populated. For example,

+     *           attribute of that service-identifier type, and join the two with a period.
+     *           For example, to filter by the `meshUid` field of the `MeshIstio`
+     *           service-identifier type, you must filter on `mesh_istio.mesh_uid =
+     *           "123"` to match all services with mesh UID "123". Service-identifier types

+/**
+ * Service Description: The SnoozeService API is used to temporarily prevent an alert policy from
+ * generating alerts. A Snooze is a description of the criteria under which one
+ * or more alert policies should not fire alerts for the specified duration.
+ *
+ * This class provides the ability to make remote calls to the backing service through method
+ * calls that map to API methods. Sample code to get started:
+ *
+ * ```
+ * $snoozeServiceClient = new SnoozeServiceClient();
+ * try {
+ *     $formattedParent = $snoozeServiceClient->workspaceName('[PROJECT]');
+ *     $snooze = new Snooze();
+ *     $response = $snoozeServiceClient->createSnooze($formattedParent, $snooze);
+ * } finally {
+ *     $snoozeServiceClient->close();
+ * }
+ * ```
+ *
+ * Many parameters require resource names to be formatted in a particular way. To
+ * assist with these names, this class includes a format method for each type of
+ * name, and additionally a parseName method to extract the individual identifiers
+ * contained within formatted names that are returned by the API.
+ *
+ * @deprecated Please use the new service client {@see \Google\Cloud\Monitoring\V3\Client\SnoozeServiceClient}.

+/**
+ * Service Description: The UptimeCheckService API is used to manage (list, create, delete, edit)
+ * Uptime check configurations in the Cloud Monitoring product. An Uptime
+ * check is a piece of configuration that determines which resources and
+ * services to monitor for availability. These configurations can also be
+ * configured interactively by navigating to the [Cloud console]
+ * (https://console.cloud.google.com), selecting the appropriate project,
+ * clicking on "Monitoring" on the left-hand side to navigate to Cloud
+ * Monitoring, and then clicking on "Uptime".
+ *
+ * This class provides the ability to make remote calls to the backing service through method
+ * calls that map to API methods. Sample code to get started:
+ *
+ * ```
+ * $uptimeCheckServiceClient = new UptimeCheckServiceClient();
+ * try {
+ *     $parent = 'parent';
+ *     $uptimeCheckConfig = new UptimeCheckConfig();
+ *     $response = $uptimeCheckServiceClient->createUptimeCheckConfig($parent, $uptimeCheckConfig);
+ * } finally {
+ *     $uptimeCheckServiceClient->close();
+ * }
+ * ```
+ *
+ * Many parameters require resource names to be formatted in a particular way. To
+ * assist with these names, this class includes a format method for each type of
+ * name, and additionally a parseName method to extract the individual identifiers
+ * contained within formatted names that are returned by the API.
+ *
+ * @deprecated Please use the new service client {@see \Google\Cloud\Monitoring\V3\Client\UptimeCheckServiceClient}.

-/**
- * Describes how to combine multiple time series to provide a different view of
- * the data.  Aggregation of time series is done in two steps. First, each time
- * series in the set is _aligned_ to the same time interval boundaries, then the
- * set of time series is optionally _reduced_ in number.
- * Alignment consists of applying the `per_series_aligner` operation
- * to each time series after its data has been divided into regular
- * `alignment_period` time intervals. This process takes _all_ of the data
- * points in an alignment period, applies a mathematical transformation such as
- * averaging, minimum, maximum, delta, etc., and converts them into a single
- * data point per period.
- * Reduction is when the aligned and transformed time series can optionally be
- * combined, reducing the number of time series through similar mathematical
- * transformations. Reduction involves applying a `cross_series_reducer` to
- * all the time series, optionally sorting the time series into subsets with
- * `group_by_fields`, and applying the reducer to each subset.
- * The raw time series data can contain a huge amount of information from
- * multiple sources. Alignment and reduction transforms this mass of data into
- * a more manageable and representative collection of data, for example "the
- * 95% latency across the average of all tasks in a cluster". This
- * representative data can be more easily graphed and comprehended, and the
- * individual time series data is still available for later drilldown. For more
- * details, see [Filtering and
- * aggregation](https://cloud.google.com/monitoring/api/v3/aggregation).

- * The description of a dynamic collection of monitored resources. Each group

- * monitored resources, and each monitored resource can be a member of any
- * number of groups.
- * Groups can be nested in parent-child hierarchies. The `parentName` field
- * identifies an optional parent for each group.  If a group has a parent, then
- * the only monitored resources available to be matched by the group's filter
- * are the resources contained in the parent group.  In other words, a group
- * contains the monitored resources that match its filter and the filters of all
- * the group's ancestors.  A group without a parent can contain any monitored
- * resource.
- * For example, consider an infrastructure running a set of instances with two
- * user-defined tags: `"environment"` and `"role"`. A parent group has a filter,
- * `environment="production"`.  A child of that parent group has a filter,
- * `role="transcoder"`.  The parent group contains all instances in the
- * production environment, regardless of their roles.  The child group contains
- * instances that have the transcoder role *and* are in the production
- * environment.
- * The monitored resources contained in a group can change at any moment,
- * depending on what resources exist and what filters are associated with the

- * Describes a time interval:

- *     must be specified, must be earlier than the end time, and should be
- *     no older than the data retention period for the metric.
- *   * Writes: A closed time interval. It extends from the start time to the end
- *   time,
- *     and includes both: `[startTime, endTime]`. Valid time intervals
- *     depend on the
- *     [`MetricKind`](https://cloud.google.com/monitoring/api/ref_v3/rest/v3/projects.metricDescriptors#MetricKind)
- *     of the metric value. The end time must not be earlier than the start
- *     time, and the end time must not be more than 25 hours in the past or more
- *     than five minutes in the future.
- *     * For `GAUGE` metrics, the `startTime` value is technically optional; if
- *       no value is specified, the start time defaults to the value of the
- *       end time, and the interval represents a single point in time. If both
- *       start and end times are specified, they must be identical. Such an
- *       interval is valid only for `GAUGE` metrics, which are point-in-time
- *       measurements. The end time of a new interval must be at least a
- *       millisecond after the end time of the previous interval.
- *     * For `DELTA` metrics, the start time and end time must specify a
- *       non-zero interval, with subsequent points specifying contiguous and
- *       non-overlapping intervals. For `DELTA` metrics, the start time of
- *       the next interval must be at least a millisecond after the end time
- *       of the previous interval.
- *     * For `CUMULATIVE` metrics, the start time and end time must specify a
- *       non-zero interval, with subsequent points specifying the same
- *       start time and increasing end times, until an event resets the
- *       cumulative value to zero and sets a new start time for the following
- *       points. The new start time must be at least a millisecond after the
- *       end time of the previous interval.
- *     * The start time of a new interval must be at least a millisecond after
- *     the
- *       end time of the previous interval because intervals are closed. If the
- *       start time of a new interval is the same as the end time of the
- *       previous interval, then data written at the new start time could

-/**
- * Service Description: The AlertPolicyService API is used to manage (list, create, delete,
- * edit) alert policies in Cloud Monitoring. An alerting policy is
- * a description of the conditions under which some aspect of your
- * system is considered to be "unhealthy" and the ways to notify
- * people or services about this state. In addition to using this API, alert
- * policies can also be managed through
- * [Cloud Monitoring](https://cloud.google.com/monitoring/docs/),
- * which can be reached by clicking the "Monitoring" tab in
- * [Cloud console](https://console.cloud.google.com/).
- *
- * This class provides the ability to make remote calls to the backing service through method
- * calls that map to API methods.
- *
- * Many parameters require resource names to be formatted in a particular way. To
- * assist with these names, this class includes a format method for each type of
- * name, and additionally a parseName method to extract the individual identifiers
- * contained within formatted names that are returned by the API.
- *

-/**
- * Service Description: The Group API lets you inspect and manage your
- * [groups](#google.monitoring.v3.Group).
- *
- * A group is a named filter that is used to identify
- * a collection of monitored resources. Groups are typically used to
- * mirror the physical and/or logical topology of the environment.
- * Because group membership is computed dynamically, monitored
- * resources that are started in the future are automatically placed
- * in matching groups. By using a group to name monitored resources in,
- * for example, an alert policy, the target of that alert policy is
- * updated automatically as monitored resources are added and removed
- * from the infrastructure.
- *
- * This class provides the ability to make remote calls to the backing service through method
- * calls that map to API methods.
- *
- * Many parameters require resource names to be formatted in a particular way. To
- * assist with these names, this class includes a format method for each type of
- * name, and additionally a parseName method to extract the individual identifiers
- * contained within formatted names that are returned by the API.

-/**
- * Service Description: The SnoozeService API is used to temporarily prevent an alert policy from
- * generating alerts. A Snooze is a description of the criteria under which one
- * or more alert policies should not fire alerts for the specified duration.
- *
- * This class provides the ability to make remote calls to the backing service through method
- * calls that map to API methods.
- *
- * Many parameters require resource names to be formatted in a particular way. To

-/**
- * Service Description: The UptimeCheckService API is used to manage (list, create, delete, edit)
- * Uptime check configurations in the Cloud Monitoring product. An Uptime
- * check is a piece of configuration that determines which resources and
- * services to monitor for availability. These configurations can also be
- * configured interactively by navigating to the [Cloud console]
- * (https://console.cloud.google.com), selecting the appropriate project,
- * clicking on "Monitoring" on the left-hand side to navigate to Cloud
- * Monitoring, and then clicking on "Uptime".
- *
- * This class provides the ability to make remote calls to the backing service through method
- * calls that map to API methods.
- *
- * Many parameters require resource names to be formatted in a particular way. To
- * assist with these names, this class includes a format method for each type of
- * name, and additionally a parseName method to extract the individual identifiers
- * contained within formatted names that are returned by the API.

-/**
- * Service Description: The AlertPolicyService API is used to manage (list, create, delete,
- * edit) alert policies in Cloud Monitoring. An alerting policy is
- * a description of the conditions under which some aspect of your
- * system is considered to be "unhealthy" and the ways to notify
- * people or services about this state. In addition to using this API, alert
- * policies can also be managed through
- * [Cloud Monitoring](https://cloud.google.com/monitoring/docs/),
- * which can be reached by clicking the "Monitoring" tab in
- * [Cloud console](https://console.cloud.google.com/).
- *
- * This class provides the ability to make remote calls to the backing service through method
- * calls that map to API methods. Sample code to get started:
- *
- * ```
- * $alertPolicyServiceClient = new AlertPolicyServiceClient();
- * try {
- *     $name = 'name';
- *     $alertPolicy = new AlertPolicy();
- *     $response = $alertPolicyServiceClient->createAlertPolicy($name, $alertPolicy);
- * } finally {
- *     $alertPolicyServiceClient->close();
- * }
- * ```
- *
- * Many parameters require resource names to be formatted in a particular way. To
- * assist with these names, this class includes a format method for each type of
- * name, and additionally a parseName method to extract the individual identifiers
- * contained within formatted names that are returned by the API.
- *
- * @deprecated Please use the new service client {@see \Google\Cloud\Monitoring\V3\Client\AlertPolicyServiceClient}.

-/**
- * Service Description: The Group API lets you inspect and manage your
- * [groups](#google.monitoring.v3.Group).
- *
- * A group is a named filter that is used to identify
- * a collection of monitored resources. Groups are typically used to
- * mirror the physical and/or logical topology of the environment.
- * Because group membership is computed dynamically, monitored
- * resources that are started in the future are automatically placed
- * in matching groups. By using a group to name monitored resources in,
- * for example, an alert policy, the target of that alert policy is
- * updated automatically as monitored resources are added and removed
- * from the infrastructure.
- *
- * This class provides the ability to make remote calls to the backing service through method
- * calls that map to API methods. Sample code to get started:
- *
- * ```
- * $groupServiceClient = new GroupServiceClient();
- * try {
- *     $name = 'name';
- *     $group = new Group();
- *     $response = $groupServiceClient->createGroup($name, $group);
- * } finally {
- *     $groupServiceClient->close();
- * }
- * ```
- *
- * Many parameters require resource names to be formatted in a particular way. To
- * assist with these names, this class includes a format method for each type of
- * name, and additionally a parseName method to extract the individual identifiers
- * contained within formatted names that are returned by the API.
- *
- * @deprecated Please use the new service client {@see \Google\Cloud\Monitoring\V3\Client\GroupServiceClient}.

-/**
- * Service Description: Manages metric descriptors, monitored resource descriptors, and
- * time series data.
- *
- * This class provides the ability to make remote calls to the backing service through method
- * calls that map to API methods. Sample code to get started:
- *
- * ```
- * $metricServiceClient = new MetricServiceClient();
- * try {
- *     $name = 'name';
- *     $metricDescriptor = new MetricDescriptor();
- *     $response = $metricServiceClient->createMetricDescriptor($name, $metricDescriptor);
- * } finally {
- *     $metricServiceClient->close();
- * }
- * ```
- *
- * Many parameters require resource names to be formatted in a particular way. To
- * assist with these names, this class includes a format method for each type of
- * name, and additionally a parseName method to extract the individual identifiers
- * contained within formatted names that are returned by the API.
- *
- * @deprecated Please use the new service client {@see \Google\Cloud\Monitoring\V3\Client\MetricServiceClient}.

-/**
- * Service Description: The Notification Channel API provides access to configuration that
- * controls how messages related to incidents are sent.
- *
- * This class provides the ability to make remote calls to the backing service through method
- * calls that map to API methods. Sample code to get started:
- *
- * ```
- * $notificationChannelServiceClient = new NotificationChannelServiceClient();
- * try {
- *     $name = 'name';
- *     $notificationChannel = new NotificationChannel();
- *     $response = $notificationChannelServiceClient->createNotificationChannel($name, $notificationChannel);
- * } finally {
- *     $notificationChannelServiceClient->close();
- * }
- * ```
- *
- * Many parameters require resource names to be formatted in a particular way. To
- * assist with these names, this class includes a format method for each type of
- * name, and additionally a parseName method to extract the individual identifiers
- * contained within formatted names that are returned by the API.
- *
- * @deprecated Please use the new service client {@see \Google\Cloud\Monitoring\V3\Client\NotificationChannelServiceClient}.

- * ```
- *
- * Many parameters require resource names to be formatted in a particular way. To
- * assist with these names, this class includes a format method for each type of

- * contained within formatted names that are returned by the API.

-/**
- * Service Description: The SnoozeService API is used to temporarily prevent an alert policy from
- * generating alerts. A Snooze is a description of the criteria under which one
- * or more alert policies should not fire alerts for the specified duration.
- *
- * This class provides the ability to make remote calls to the backing service through method
- * calls that map to API methods. Sample code to get started:
- *
- * ```
- * $snoozeServiceClient = new SnoozeServiceClient();
- * try {
- *     $formattedParent = $snoozeServiceClient->workspaceName('[PROJECT]');
- *     $snooze = new Snooze();
- *     $response = $snoozeServiceClient->createSnooze($formattedParent, $snooze);
- * } finally {
- *     $snoozeServiceClient->close();
- * }
- * ```
- *
- * Many parameters require resource names to be formatted in a particular way. To
- * assist with these names, this class includes a format method for each type of
- * name, and additionally a parseName method to extract the individual identifiers
- * contained within formatted names that are returned by the API.
- *
- * @deprecated Please use the new service client {@see \Google\Cloud\Monitoring\V3\Client\SnoozeServiceClient}.

-/**
- * Service Description: The UptimeCheckService API is used to manage (list, create, delete, edit)
- * Uptime check configurations in the Cloud Monitoring product. An Uptime
- * check is a piece of configuration that determines which resources and
- * services to monitor for availability. These configurations can also be
- * configured interactively by navigating to the [Cloud console]
- * (https://console.cloud.google.com), selecting the appropriate project,
- * clicking on "Monitoring" on the left-hand side to navigate to Cloud
- * Monitoring, and then clicking on "Uptime".
- *
- * This class provides the ability to make remote calls to the backing service through method
- * calls that map to API methods. Sample code to get started:
- *
- * ```
- * $uptimeCheckServiceClient = new UptimeCheckServiceClient();
- * try {
- *     $parent = 'parent';
- *     $uptimeCheckConfig = new UptimeCheckConfig();
- *     $response = $uptimeCheckServiceClient->createUptimeCheckConfig($parent, $uptimeCheckConfig);
- * } finally {
- *     $uptimeCheckServiceClient->close();
- * }
- * ```
- *
- * Many parameters require resource names to be formatted in a particular way. To
- * assist with these names, this class includes a format method for each type of
- * name, and additionally a parseName method to extract the individual identifiers
- * contained within formatted names that are returned by the API.
- *
- * @deprecated Please use the new service client {@see \Google\Cloud\Monitoring\V3\Client\UptimeCheckServiceClient}.

+/**
+ * Describes how to combine multiple time series to provide a different view of
+ * the data.  Aggregation of time series is done in two steps. First, each time
+ * series in the set is _aligned_ to the same time interval boundaries, then the
+ * set of time series is optionally _reduced_ in number.
+ * Alignment consists of applying the `per_series_aligner` operation
+ * to each time series after its data has been divided into regular
+ * `alignment_period` time intervals. This process takes _all_ of the data
+ * points in an alignment period, applies a mathematical transformation such as
+ * averaging, minimum, maximum, delta, etc., and converts them into a single
+ * data point per period.
+ * Reduction is when the aligned and transformed time series can optionally be
+ * combined, reducing the number of time series through similar mathematical
+ * transformations. Reduction involves applying a `cross_series_reducer` to
+ * all the time series, optionally sorting the time series into subsets with
+ * `group_by_fields`, and applying the reducer to each subset.
+ * The raw time series data can contain a huge amount of information from
+ * multiple sources. Alignment and reduction transforms this mass of data into
+ * a more manageable and representative collection of data, for example "the
+ * 95% latency across the average of all tasks in a cluster". This
+ * representative data can be more easily graphed and comprehended, and the
+ * individual time series data is still available for later drilldown. For more
+ * details, see [Filtering and
+ * aggregation](https://cloud.google.com/monitoring/api/v3/aggregation).

+ * Because Cloud Alerting has no representation of a Prometheus rule

+/**
+ * The description of a dynamic collection of monitored resources. Each group
+ * has a filter that is matched against monitored resources and their associated
+ * metadata. If a group's filter matches an available monitored resource, then
+ * that resource is a member of that group.  Groups can contain any number of
+ * monitored resources, and each monitored resource can be a member of any
+ * number of groups.
+ * Groups can be nested in parent-child hierarchies. The `parentName` field
+ * identifies an optional parent for each group.  If a group has a parent, then
+ * the only monitored resources available to be matched by the group's filter
+ * are the resources contained in the parent group.  In other words, a group
+ * contains the monitored resources that match its filter and the filters of all
+ * the group's ancestors.  A group without a parent can contain any monitored
+ * resource.
+ * For example, consider an infrastructure running a set of instances with two
+ * user-defined tags: `"environment"` and `"role"`. A parent group has a filter,
+ * `environment="production"`.  A child of that parent group has a filter,
+ * `role="transcoder"`.  The parent group contains all instances in the
+ * production environment, regardless of their roles.  The child group contains
+ * instances that have the transcoder role *and* are in the production
+ * environment.
+ * The monitored resources contained in a group can change at any moment,
+ * depending on what resources exist and what filters are associated with the
+ * group and its ancestors.

+ *       no value is specified, the start time defaults to the value of the
+ *       end time, and the interval represents a single point in time. If both
+ *       start and end times are specified, they must be identical. Such an
+ *       interval is valid only for `GAUGE` metrics, which are point-in-time
+ *       measurements. The end time of a new interval must be at least a
+ *       millisecond after the end time of the previous interval.
+ *     * For `DELTA` metrics, the start time and end time must specify a
+ *       non-zero interval, with subsequent points specifying contiguous and
+ *       non-overlapping intervals. For `DELTA` metrics, the start time of
+ *       the next interval must be at least a millisecond after the end time
+ *       of the previous interval.
+ *     * For `CUMULATIVE` metrics, the start time and end time must specify a
+ *       non-zero interval, with subsequent points specifying the same
+ *       start time and increasing end times, until an event resets the
+ *       cumulative value to zero and sets a new start time for the following
+ *       points. The new start time must be at least a millisecond after the
+ *       end time of the previous interval.
+ *     * The start time of a new interval must be at least a millisecond after
+ *     the
+ *       end time of the previous interval because intervals are closed. If the
+ *       start time of a new interval is the same as the end time of the
+ *       previous interval, then data written at the new start time could
+ *       overwrite data written at the previous end time.

+/**
+ * Service Description: The AlertPolicyService API is used to manage (list, create, delete,
+ * edit) alert policies in Cloud Monitoring. An alerting policy is
+ * a description of the conditions under which some aspect of your
+ * system is considered to be "unhealthy" and the ways to notify
+ * people or services about this state. In addition to using this API, alert
+ * policies can also be managed through
+ * [Cloud Monitoring](https://cloud.google.com/monitoring/docs/),
+ * which can be reached by clicking the "Monitoring" tab in
+ * [Cloud console](https://console.cloud.google.com/).
+ *
+ * This class provides the ability to make remote calls to the backing service through method
+ * calls that map to API methods.
+ *
+ * Many parameters require resource names to be formatted in a particular way. To

+/**
+ * Service Description: The Group API lets you inspect and manage your
+ * [groups](#google.monitoring.v3.Group).
+ *
+ * A group is a named filter that is used to identify
+ * a collection of monitored resources. Groups are typically used to
+ * mirror the physical and/or logical topology of the environment.
+ * Because group membership is computed dynamically, monitored
+ * resources that are started in the future are automatically placed
+ * in matching groups. By using a group to name monitored resources in,
+ * for example, an alert policy, the target of that alert policy is
+ * updated automatically as monitored resources are added and removed
+ * from the infrastructure.
+ *
+ * This class provides the ability to make remote calls to the backing service through method
+ * calls that map to API methods.
+ *
+ * Many parameters require resource names to be formatted in a particular way. To
+ * assist with these names, this class includes a format method for each type of
+ * name, and additionally a parseName method to extract the individual identifiers
+ * contained within formatted names that are returned by the API.

+/**
+ * Service Description: The UptimeCheckService API is used to manage (list, create, delete, edit)
+ * Uptime check configurations in the Cloud Monitoring product. An Uptime
+ * check is a piece of configuration that determines which resources and
+ * services to monitor for availability. These configurations can also be
+ * configured interactively by navigating to the [Cloud console]
+ * (https://console.cloud.google.com), selecting the appropriate project,
+ * clicking on "Monitoring" on the left-hand side to navigate to Cloud
+ * Monitoring, and then clicking on "Uptime".
+ *
+ * This class provides the ability to make remote calls to the backing service through method
+ * calls that map to API methods.
+ *
+ * Many parameters require resource names to be formatted in a particular way. To
+ * assist with these names, this class includes a format method for each type of
+ * name, and additionally a parseName method to extract the individual identifiers
+ * contained within formatted names that are returned by the API.
+ *

+/**
+ * Service Description: The AlertPolicyService API is used to manage (list, create, delete,
+ * edit) alert policies in Cloud Monitoring. An alerting policy is
+ * a description of the conditions under which some aspect of your
+ * system is considered to be "unhealthy" and the ways to notify
+ * people or services about this state. In addition to using this API, alert
+ * policies can also be managed through
+ * [Cloud Monitoring](https://cloud.google.com/monitoring/docs/),
+ * which can be reached by clicking the "Monitoring" tab in
+ * [Cloud console](https://console.cloud.google.com/).
+ *
+ * This class provides the ability to make remote calls to the backing service through method
+ * calls that map to API methods. Sample code to get started:
+ *
+ * ```
+ * $alertPolicyServiceClient = new AlertPolicyServiceClient();
+ * try {
+ *     $name = 'name';
+ *     $alertPolicy = new AlertPolicy();
+ *     $response = $alertPolicyServiceClient->createAlertPolicy($name, $alertPolicy);
+ * } finally {
+ *     $alertPolicyServiceClient->close();
+ * }
+ * ```
+ *
+ * Many parameters require resource names to be formatted in a particular way. To
+ * assist with these names, this class includes a format method for each type of
+ * name, and additionally a parseName method to extract the individual identifiers
+ * contained within formatted names that are returned by the API.
+ *
+ * @deprecated Please use the new service client {@see \Google\Cloud\Monitoring\V3\Client\AlertPolicyServiceClient}.

+/**
+ * Service Description: The Group API lets you inspect and manage your
+ * [groups](#google.monitoring.v3.Group).
+ *
+ * A group is a named filter that is used to identify
+ * a collection of monitored resources. Groups are typically used to
+ * mirror the physical and/or logical topology of the environment.
+ * Because group membership is computed dynamically, monitored
+ * resources that are started in the future are automatically placed
+ * in matching groups. By using a group to name monitored resources in,
+ * for example, an alert policy, the target of that alert policy is
+ * updated automatically as monitored resources are added and removed
+ * from the infrastructure.
+ *
+ * This class provides the ability to make remote calls to the backing service through method
+ * calls that map to API methods. Sample code to get started:
+ *
+ * ```
+ * $groupServiceClient = new GroupServiceClient();
+ * try {
+ *     $name = 'name';
+ *     $group = new Group();
+ *     $response = $groupServiceClient->createGroup($name, $group);
+ * } finally {
+ *     $groupServiceClient->close();
+ * }
+ * ```
+ *
+ * Many parameters require resource names to be formatted in a particular way. To
+ * assist with these names, this class includes a format method for each type of
+ * name, and additionally a parseName method to extract the individual identifiers
+ * contained within formatted names that are returned by the API.
+ *
+ * @deprecated Please use the new service client {@see \Google\Cloud\Monitoring\V3\Client\GroupServiceClient}.

+ *
+ * Many parameters require resource names to be formatted in a particular way. To
+ * assist with these names, this class includes a format method for each type of
+ * name, and additionally a parseName method to extract the individual identifiers
+ * contained within formatted names that are returned by the API.

+/**
+ * Service Description: The Notification Channel API provides access to configuration that
+ * controls how messages related to incidents are sent.
+ *
+ * This class provides the ability to make remote calls to the backing service through method
+ * calls that map to API methods. Sample code to get started:
+ *
+ * ```
+ * $notificationChannelServiceClient = new NotificationChannelServiceClient();
+ * try {
+ *     $name = 'name';
+ *     $notificationChannel = new NotificationChannel();
+ *     $response = $notificationChannelServiceClient->createNotificationChannel($name, $notificationChannel);
+ * } finally {
+ *     $notificationChannelServiceClient->close();
+ * }
+ * ```
+ *
+ * Many parameters require resource names to be formatted in a particular way. To
+ * assist with these names, this class includes a format method for each type of
+ * name, and additionally a parseName method to extract the individual identifiers
+ * contained within formatted names that are returned by the API.
+ *
+ * @deprecated Please use the new service client {@see \Google\Cloud\Monitoring\V3\Client\NotificationChannelServiceClient}.

+/**
+ * Service Description: The Cloud Monitoring Service-Oriented Monitoring API has endpoints for
+ * managing and querying aspects of a Metrics Scope's services. These include
+ * the `Service`'s monitored resources, its Service-Level Objectives, and a
+ * taxonomy of categorized Health Metrics.
+ *
+ * This class provides the ability to make remote calls to the backing service through method
+ * calls that map to API methods. Sample code to get started:
+ *
+ * ```
+ * $serviceMonitoringServiceClient = new ServiceMonitoringServiceClient();
+ * try {
+ *     $parent = 'parent';
+ *     $service = new Service();
+ *     $response = $serviceMonitoringServiceClient->createService($parent, $service);
+ * } finally {
+ *     $serviceMonitoringServiceClient->close();
+ * }
+ * ```
+ *
+ * Many parameters require resource names to be formatted in a particular way. To
+ * assist with these names, this class includes a format method for each type of
+ * name, and additionally a parseName method to extract the individual identifiers
+ * contained within formatted names that are returned by the API.
+ *
+ * @deprecated Please use the new service client {@see \Google\Cloud\Monitoring\V3\Client\ServiceMonitoringServiceClient}.

+     *
+     *           To filter on a particular service-identifier type, the `identifier_case`
+     *           refers to which option in the `identifier` field is populated. For example,

+     *           For example, to filter by the `meshUid` field of the `MeshIstio`
+     *           service-identifier type, you must filter on `mesh_istio.mesh_uid =
+     *           "123"` to match all services with mesh UID "123". Service-identifier types

+/**
+ * Service Description: The SnoozeService API is used to temporarily prevent an alert policy from
+ * generating alerts. A Snooze is a description of the criteria under which one
+ * or more alert policies should not fire alerts for the specified duration.
+ *
+ * This class provides the ability to make remote calls to the backing service through method
+ * calls that map to API methods. Sample code to get started:
+ *
+ * ```
+ * $snoozeServiceClient = new SnoozeServiceClient();
+ * try {
+ *     $formattedParent = $snoozeServiceClient->workspaceName('[PROJECT]');
+ *     $snooze = new Snooze();
+ *     $response = $snoozeServiceClient->createSnooze($formattedParent, $snooze);
+ * } finally {
+ *     $snoozeServiceClient->close();
+ * }
+ * ```
+ *
+ * Many parameters require resource names to be formatted in a particular way. To
+ * assist with these names, this class includes a format method for each type of
+ * name, and additionally a parseName method to extract the individual identifiers
+ * contained within formatted names that are returned by the API.
+ *
+ * @deprecated Please use the new service client {@see \Google\Cloud\Monitoring\V3\Client\SnoozeServiceClient}.

+/**
+ * Service Description: The UptimeCheckService API is used to manage (list, create, delete, edit)
+ * Uptime check configurations in the Cloud Monitoring product. An Uptime
+ * check is a piece of configuration that determines which resources and
+ * services to monitor for availability. These configurations can also be
+ * configured interactively by navigating to the [Cloud console]
+ * (https://console.cloud.google.com), selecting the appropriate project,
+ * clicking on "Monitoring" on the left-hand side to navigate to Cloud
+ * Monitoring, and then clicking on "Uptime".
+ *
+ * This class provides the ability to make remote calls to the backing service through method
+ * calls that map to API methods. Sample code to get started:
+ *
+ * ```
+ * $uptimeCheckServiceClient = new UptimeCheckServiceClient();
+ * try {
+ *     $parent = 'parent';
+ *     $uptimeCheckConfig = new UptimeCheckConfig();
+ *     $response = $uptimeCheckServiceClient->createUptimeCheckConfig($parent, $uptimeCheckConfig);
+ * } finally {
+ *     $uptimeCheckServiceClient->close();
+ * }
+ * ```
+ *
+ * Many parameters require resource names to be formatted in a particular way. To
+ * assist with these names, this class includes a format method for each type of
+ * name, and additionally a parseName method to extract the individual identifiers
+ * contained within formatted names that are returned by the API.
+ *
+ * @deprecated Please use the new service client {@see \Google\Cloud\Monitoring\V3\Client\UptimeCheckServiceClient}.

-/**
- * Describes how to combine multiple time series to provide a different view of
- * the data.  Aggregation of time series is done in two steps. First, each time
- * series in the set is _aligned_ to the same time interval boundaries, then the
- * set of time series is optionally _reduced_ in number.
- * Alignment consists of applying the `per_series_aligner` operation
- * to each time series after its data has been divided into regular
- * `alignment_period` time intervals. This process takes _all_ of the data
- * points in an alignment period, applies a mathematical transformation such as
- * averaging, minimum, maximum, delta, etc., and converts them into a single
- * data point per period.
- * Reduction is when the aligned and transformed time series can optionally be
- * combined, reducing the number of time series through similar mathematical
- * transformations. Reduction involves applying a `cross_series_reducer` to
- * all the time series, optionally sorting the time series into subsets with
- * `group_by_fields`, and applying the reducer to each subset.
- * The raw time series data can contain a huge amount of information from
- * multiple sources. Alignment and reduction transforms this mass of data into
- * a more manageable and representative collection of data, for example "the
- * 95% latency across the average of all tasks in a cluster". This
- * representative data can be more easily graphed and comprehended, and the
- * individual time series data is still available for later drilldown. For more
- * details, see [Filtering and
- * aggregation](https://cloud.google.com/monitoring/api/v3/aggregation).

- * The description of a dynamic collection of monitored resources. Each group

- * monitored resources, and each monitored resource can be a member of any
- * number of groups.
- * Groups can be nested in parent-child hierarchies. The `parentName` field
- * identifies an optional parent for each group.  If a group has a parent, then
- * the only monitored resources available to be matched by the group's filter
- * are the resources contained in the parent group.  In other words, a group
- * contains the monitored resources that match its filter and the filters of all
- * the group's ancestors.  A group without a parent can contain any monitored
- * resource.
- * For example, consider an infrastructure running a set of instances with two
- * user-defined tags: `"environment"` and `"role"`. A parent group has a filter,
- * `environment="production"`.  A child of that parent group has a filter,
- * `role="transcoder"`.  The parent group contains all instances in the
- * production environment, regardless of their roles.  The child group contains
- * instances that have the transcoder role *and* are in the production
- * environment.
- * The monitored resources contained in a group can change at any moment,

- * Describes a time interval:

- *     must be specified, must be earlier than the end time, and should be
- *     no older than the data retention period for the metric.
- *   * Writes: A closed time interval. It extends from the start time to the end
- *   time,
- *     and includes both: `[startTime, endTime]`. Valid time intervals
- *     depend on the
- *     [`MetricKind`](https://cloud.google.com/monitoring/api/ref_v3/rest/v3/projects.metricDescriptors#MetricKind)
- *     of the metric value. The end time must not be earlier than the start
- *     time, and the end time must not be more than 25 hours in the past or more
- *     than five minutes in the future.
- *     * For `GAUGE` metrics, the `startTime` value is technically optional; if
- *       no value is specified, the start time defaults to the value of the
- *       end time, and the interval represents a single point in time. If both
- *       start and end times are specified, they must be identical. Such an
- *       interval is valid only for `GAUGE` metrics, which are point-in-time
- *       measurements. The end time of a new interval must be at least a
- *       millisecond after the end time of the previous interval.
- *     * For `DELTA` metrics, the start time and end time must specify a
- *       non-zero interval, with subsequent points specifying contiguous and
- *       non-overlapping intervals. For `DELTA` metrics, the start time of
- *       the next interval must be at least a millisecond after the end time
- *       of the previous interval.
- *     * For `CUMULATIVE` metrics, the start time and end time must specify a
- *       non-zero interval, with subsequent points specifying the same
- *       start time and increasing end times, until an event resets the
- *       cumulative value to zero and sets a new start time for the following
- *       points. The new start time must be at least a millisecond after the
- *       end time of the previous interval.
- *     * The start time of a new interval must be at least a millisecond after
- *     the
- *       end time of the previous interval because intervals are closed. If the
- *       start time of a new interval is the same as the end time of the
- *       previous interval, then data written at the new start time could

-/**
- * Service Description: The AlertPolicyService API is used to manage (list, create, delete,
- * edit) alert policies in Cloud Monitoring. An alerting policy is
- * a description of the conditions under which some aspect of your
- * system is considered to be "unhealthy" and the ways to notify
- * people or services about this state. In addition to using this API, alert
- * policies can also be managed through
- * [Cloud Monitoring](https://cloud.google.com/monitoring/docs/),
- * which can be reached by clicking the "Monitoring" tab in
- * [Cloud console](https://console.cloud.google.com/).
- *
- * This class provides the ability to make remote calls to the backing service through method
- * calls that map to API methods.
- *
- * Many parameters require resource names to be formatted in a particular way. To
- * assist with these names, this class includes a format method for each type of
- * name, and additionally a parseName method to extract the individual identifiers
- * contained within formatted names that are returned by the API.
- *

-/**
- * Service Description: The Group API lets you inspect and manage your
- * [groups](#google.monitoring.v3.Group).
- *
- * A group is a named filter that is used to identify
- * a collection of monitored resources. Groups are typically used to
- * mirror the physical and/or logical topology of the environment.
- * Because group membership is computed dynamically, monitored
- * resources that are started in the future are automatically placed
- * in matching groups. By using a group to name monitored resources in,
- * for example, an alert policy, the target of that alert policy is
- * updated automatically as monitored resources are added and removed
- * from the infrastructure.
- *
- * This class provides the ability to make remote calls to the backing service through method
- * calls that map to API methods.
- *
- * Many parameters require resource names to be formatted in a particular way. To
- * assist with these names, this class includes a format method for each type of
- * name, and additionally a parseName method to extract the individual identifiers
- * contained within formatted names that are returned by the API.

-     *     @type string|array $clientConfig
-     *           Client method configuration, including retry settings. This option can be either
-     *           a path to a JSON file, or a PHP array containing the decoded JSON data. By
-     *           default this settings points to the default client config file, which is

-     *     @type string|TransportInterface $transport
-     *           The transport used for executing network requests. May be either the string
-     *           `rest` or `grpc`. Defaults to `grpc` if gRPC support is detected on the system.
-     *           *Advanced usage*: Additionally, it is possible to pass in an already

-/**
- * Service Description: The AlertPolicyService API is used to manage (list, create, delete,
- * edit) alert policies in Cloud Monitoring. An alerting policy is
- * a description of the conditions under which some aspect of your
- * system is considered to be "unhealthy" and the ways to notify
- * people or services about this state. In addition to using this API, alert
- * policies can also be managed through
- * [Cloud Monitoring](https://cloud.google.com/monitoring/docs/),
- * which can be reached by clicking the "Monitoring" tab in
- * [Cloud console](https://console.cloud.google.com/).
- *
- * This class provides the ability to make remote calls to the backing service through method
- * calls that map to API methods. Sample code to get started:
- *
- * ```
- * $alertPolicyServiceClient = new AlertPolicyServiceClient();
- * try {
- *     $name = 'name';
- *     $alertPolicy = new AlertPolicy();
- *     $response = $alertPolicyServiceClient->createAlertPolicy($name, $alertPolicy);
- * } finally {
- *     $alertPolicyServiceClient->close();
- * }
- * ```
- *
- * Many parameters require resource names to be formatted in a particular way. To
- * assist with these names, this class includes a format method for each type of
- * name, and additionally a parseName method to extract the individual identifiers
- * contained within formatted names that are returned by the API.
- *
- * @deprecated Please use the new service client {@see \Google\Cloud\Monitoring\V3\Client\AlertPolicyServiceClient}.

-/**
- * Service Description: The Group API lets you inspect and manage your
- * [groups](#google.monitoring.v3.Group).
- *
- * A group is a named filter that is used to identify
- * a collection of monitored resources. Groups are typically used to
- * mirror the physical and/or logical topology of the environment.
- * Because group membership is computed dynamically, monitored
- * resources that are started in the future are automatically placed
- * in matching groups. By using a group to name monitored resources in,
- * for example, an alert policy, the target of that alert policy is
- * updated automatically as monitored resources are added and removed
- * from the infrastructure.
- *
- * This class provides the ability to make remote calls to the backing service through method
- * calls that map to API methods. Sample code to get started:
- *
- * ```
- * $groupServiceClient = new GroupServiceClient();
- * try {
- *     $name = 'name';
- *     $group = new Group();
- *     $response = $groupServiceClient->createGroup($name, $group);
- * } finally {
- *     $groupServiceClient->close();
- * }
- * ```
- *
- * Many parameters require resource names to be formatted in a particular way. To
- * assist with these names, this class includes a format method for each type of
- * name, and additionally a parseName method to extract the individual identifiers
- * contained within formatted names that are returned by the API.
- *
- * @deprecated Please use the new service client {@see \Google\Cloud\Monitoring\V3\Client\GroupServiceClient}.

-/**
- * Service Description: Manages metric descriptors, monitored resource descriptors, and
- * time series data.
- *
- * This class provides the ability to make remote calls to the backing service through method
- * calls that map to API methods. Sample code to get started:
- *
- * ```
- * $metricServiceClient = new MetricServiceClient();
- * try {
- *     $name = 'name';
- *     $metricDescriptor = new MetricDescriptor();
- *     $response = $metricServiceClient->createMetricDescriptor($name, $metricDescriptor);
- * } finally {
- *     $metricServiceClient->close();
- * }
- * ```
- *
- * Many parameters require resource names to be formatted in a particular way. To
- * assist with these names, this class includes a format method for each type of
- * name, and additionally a parseName method to extract the individual identifiers
- * contained within formatted names that are returned by the API.
- *
- * @deprecated Please use the new service client {@see \Google\Cloud\Monitoring\V3\Client\MetricServiceClient}.

-/**
- * Service Description: The Notification Channel API provides access to configuration that
- * controls how messages related to incidents are sent.
- *
- * This class provides the ability to make remote calls to the backing service through method
- * calls that map to API methods. Sample code to get started:
- *
- * ```
- * $notificationChannelServiceClient = new NotificationChannelServiceClient();
- * try {
- *     $name = 'name';
- *     $notificationChannel = new NotificationChannel();
- *     $response = $notificationChannelServiceClient->createNotificationChannel($name, $notificationChannel);
- * } finally {
- *     $notificationChannelServiceClient->close();
- * }
- * ```
- *
- * Many parameters require resource names to be formatted in a particular way. To
- * assist with these names, this class includes a format method for each type of
- * name, and additionally a parseName method to extract the individual identifiers
- * contained within formatted names that are returned by the API.
- *
- * @deprecated Please use the new service client {@see \Google\Cloud\Monitoring\V3\Client\NotificationChannelServiceClient}.

-/**
- * Service Description: The Cloud Monitoring Service-Oriented Monitoring API has endpoints for
- * managing and querying aspects of a Metrics Scope's services. These include
- * the `Service`'s monitored resources, its Service-Level Objectives, and a
- * taxonomy of categorized Health Metrics.
- *
- * This class provides the ability to make remote calls to the backing service through method
- * calls that map to API methods. Sample code to get started:
- *
- * ```
- * $serviceMonitoringServiceClient = new ServiceMonitoringServiceClient();
- * try {
- *     $parent = 'parent';
- *     $service = new Service();
- *     $response = $serviceMonitoringServiceClient->createService($parent, $service);
- * } finally {
- *     $serviceMonitoringServiceClient->close();
- * }
- * ```
- *
- * Many parameters require resource names to be formatted in a particular way. To
- * assist with these names, this class includes a format method for each type of
- * name, and additionally a parseName method to extract the individual identifiers
- * contained within formatted names that are returned by the API.
- *
- * @deprecated Please use the new service client {@see \Google\Cloud\Monitoring\V3\Client\ServiceMonitoringServiceClient}.

-/**
- * Service Description: The SnoozeService API is used to temporarily prevent an alert policy from
- * generating alerts. A Snooze is a description of the criteria under which one
- * or more alert policies should not fire alerts for the specified duration.
- *
- * This class provides the ability to make remote calls to the backing service through method
- * calls that map to API methods. Sample code to get started:
- *
- * ```
- * $snoozeServiceClient = new SnoozeServiceClient();
- * try {
- *     $formattedParent = $snoozeServiceClient->workspaceName('[PROJECT]');
- *     $snooze = new Snooze();
- *     $response = $snoozeServiceClient->createSnooze($formattedParent, $snooze);
- * } finally {
- *     $snoozeServiceClient->close();
- * }
- * ```
- *
- * Many parameters require resource names to be formatted in a particular way. To
- * assist with these names, this class includes a format method for each type of
- * name, and additionally a parseName method to extract the individual identifiers
- * contained within formatted names that are returned by the API.
- *
- * @deprecated Please use the new service client {@see \Google\Cloud\Monitoring\V3\Client\SnoozeServiceClient}.

-/**
- * Service Description: The UptimeCheckService API is used to manage (list, create, delete, edit)
- * Uptime check configurations in the Cloud Monitoring product. An Uptime
- * check is a piece of configuration that determines which resources and
- * services to monitor for availability. These configurations can also be
- * configured interactively by navigating to the [Cloud console]
- * (https://console.cloud.google.com), selecting the appropriate project,
- * clicking on "Monitoring" on the left-hand side to navigate to Cloud
- * Monitoring, and then clicking on "Uptime".
- *
- * This class provides the ability to make remote calls to the backing service through method
- * calls that map to API methods. Sample code to get started:
- *
- * ```
- * $uptimeCheckServiceClient = new UptimeCheckServiceClient();
- * try {
- *     $parent = 'parent';
- *     $uptimeCheckConfig = new UptimeCheckConfig();
- *     $response = $uptimeCheckServiceClient->createUptimeCheckConfig($parent, $uptimeCheckConfig);
- * } finally {
- *     $uptimeCheckServiceClient->close();
- * }
- * ```
- *
- * Many parameters require resource names to be formatted in a particular way. To
- * assist with these names, this class includes a format method for each type of
- * name, and additionally a parseName method to extract the individual identifiers
- * contained within formatted names that are returned by the API.
- *
- * @deprecated Please use the new service client {@see \Google\Cloud\Monitoring\V3\Client\UptimeCheckServiceClient}.
