Amazon ELB

The Amazon ELB integration allows you to monitor Amazon Elastic Load Balancing (ELB)—a tool that distributes application traffic to multiple targets.

Use the Amazon ELB integration to collect logs and metrics with detailed information about requests sent to the load balancer. Then visualize that data in Kibana, create alerts to notify you if something goes wrong, and reference those logs and metrics when troubleshooting an issue.

For example, you could use this data to analyze traffic patterns, view healthy and unhealthy hosts, and track connection and backend errors.

IMPORTANT: Extra AWS charges on AWS API requests will be generated by this integration. Please refer to the AWS integration for more details.

Data streams

The Amazon ELB integration collects two types of data: logs and metrics.

Logs help you keep a record of events happening in Amazon ELB. Logs collected by the Amazon ELB integration include the time a request was received, the client's IP address, latencies, request paths, server responses, and more. See more details in the Logs reference.

Metrics give you insight into the state of Amazon ELB. Metrics collected by the Amazon ELB integration include the host name, IP address, average latency, and more. See more details in the Metrics reference.

Requirements

You need Elasticsearch for storing and searching your data and Kibana for visualizing and managing it. You can use our hosted Elasticsearch Service on Elastic Cloud, which is recommended, or self-manage the Elastic Stack on your own hardware.

Before using any AWS integration you will need:

  • AWS Credentials to connect with your AWS account.
  • AWS Permissions to make sure the user you're using to connect has permission to share the relevant data.

For more details about these requirements, please take a look at the AWS integration documentation.

Setup

Use this integration if you only need to collect data from the Amazon ELB service.

If you want to collect data from two or more AWS services, consider using the AWS integration. When you configure the AWS integration, you can collect data from as many AWS services as you'd like.

For step-by-step instructions on how to set up an integration, see the Getting started guide.

To send classic ELB access logs to an S3 bucket, see enable access logs for classic load balancer.

For an application load balancer, see enable access log for application load balancer.

For a network load balancer, see enable access log for network load balancer.

Advanced options

CloudWatch

The CloudWatch logs input has several advanced options to fit specific use cases.

Latency

AWS CloudWatch Logs sometimes takes extra time to make the latest logs available to clients like the Agent.

The CloudWatch integration offers the latency setting to address this scenario. Latency translates the query's time range to consider the CloudWatch Logs latency. For example, a 5m latency means the integration will query CloudWatch for logs available 5 minutes ago.

Number of workers

If you are collecting log events from multiple log groups using log_group_name_prefix, you should review the value of the number_of_workers.

The number_of_workers setting defines the number of workers assigned to reading from log groups. Each log group matching the log_group_name_prefix requires a worker to keep log ingestion as close to real-time as possible. For example, if log_group_name_prefix matches five log groups, then number_of_workers should be set to 5. The default value is 1.

Logs reference

The elb dataset collects logs from AWS ELBs.

destination.domain The domain name of the destination system. This value may be a host name, a fully qualified domain name, or another host naming format. The value may derive from the original event or be added from enrichment. keyword
ecs.version ECS version this event conforms to. ecs.version is a required field and must exist in all events. When querying across multiple indices -- which may conform to slightly different ECS versions -- this field lets integrations adjust to the schema version of the events. keyword
error.message Error message. match_only_text
event.category This is one of four ECS Categorization Fields, and indicates the second level in the ECS category hierarchy. event.category represents the "big buckets" of ECS categories. For example, filtering on event.category:process yields all events relating to process activity. This field is closely related to event.type, which is used as a subcategory. This field is an array. This will allow proper categorization of some events that fall in multiple categories. keyword
event.dataset Event dataset constant_keyword
event.end event.end contains the date when the event ended or when the activity was last observed. date
event.kind This is one of four ECS Categorization Fields, and indicates the highest level in the ECS category hierarchy. event.kind gives high-level information about what type of information the event contains, without being specific to the contents of the event. For example, values of this field distinguish alert events from metric events. The value of this field can be used to inform how these kinds of events should be handled. They may warrant different retention, different access control, it may also help understand whether the data is coming in at a regular interval or not. keyword
event.module Event module constant_keyword
event.outcome This is one of four ECS Categorization Fields, and indicates the lowest level in the ECS category hierarchy. event.outcome simply denotes whether the event represents a success or a failure from the perspective of the entity that produced the event. Note that when a single transaction is described in multiple events, each event may populate different values of event.outcome, according to their perspective. Also note that in the case of a compound event (a single event that contains multiple logical events), this field should be populated with the value that best captures the overall success or failure from the perspective of the event producer. Further note that not all events will have an associated outcome. For example, this field is generally not populated for metric events, events with event.type:info, or any events for which an outcome does not make logical sense. keyword
event.start event.start contains the date when the event started or when the activity was first observed. date
host.architecture Operating system architecture. keyword
host.containerized If the host is a container. boolean
host.domain Name of the domain of which the host is a member. For example, on Windows this could be the host's Active Directory domain or NetBIOS domain name. For Linux this could be the domain of the host's LDAP provider. keyword
host.hostname Hostname of the host. It normally contains what the hostname command returns on the host machine. keyword
host.id Unique host id. As hostname is not always unique, use values that are meaningful in your environment. Example: The current usage of beat.name. keyword
host.ip Host ip addresses. ip
host.mac Host MAC addresses. The notation format from RFC 7042 is suggested: Each octet (that is, 8-bit byte) is represented by two [uppercase] hexadecimal digits giving the value of the octet as an unsigned integer. Successive octets are separated by a hyphen. keyword
host.name Name of the host. It can contain what hostname returns on Unix systems, the fully qualified domain name (FQDN), or a name specified by the user. The recommended value is the lowercase FQDN of the host. keyword
host.os.build OS build information. keyword
host.os.codename OS codename, if any. keyword
host.os.family OS family (such as redhat, debian, freebsd, windows). keyword
host.os.kernel Operating system kernel version as a raw string. keyword
host.os.name Operating system name, without the version. keyword
host.os.name.text Multi-field of host.os.name. match_only_text
host.os.platform Operating system platform (such centos, ubuntu, windows). keyword
host.os.version Operating system version as a raw string. keyword
host.type Type of host. For Cloud providers this can be the machine type like t2.medium. If vm, this could be the container, for example, or other information meaningful in your environment. keyword
http.request.body.bytes Size in bytes of the request body. long
http.request.method HTTP request method. The value should retain its casing from the original event. For example, GET, get, and GeT are all considered valid values for this field. keyword
http.request.referrer Referrer for this HTTP request. keyword
http.response.body.bytes Size in bytes of the response body. long
http.response.status_code HTTP response status code. long
http.version HTTP version. keyword
source.address Some event source addresses are defined ambiguously. The event will sometimes list an IP, a domain or a unix socket. You should always store the raw address in the .address field. Then it should be duplicated to .ip or .domain, depending on which one it is. keyword
source.as.number Unique number allocated to the autonomous system. The autonomous system number (ASN) uniquely identifies each network on the Internet. long
source.as.organization.name Organization name. keyword
source.as.organization.name.text Multi-field of source.as.organization.name. match_only_text
source.geo.city_name City name. keyword
source.geo.continent_name Name of the continent. keyword
source.geo.country_iso_code Country ISO code. keyword
source.geo.country_name Country name. keyword
source.geo.location Longitude and latitude. geo_point
source.geo.region_name Region name. keyword
source.ip IP address of the source (IPv4 or IPv6). ip
source.port Port of the source. long
tags List of keywords used to tag each event. keyword
trace.id Unique identifier of the trace. A trace groups multiple events like transactions that belong together. For example, a user request handled by multiple inter-connected services. keyword
url.domain Domain of the url, such as "www.elastic.co". In some cases a URL may refer to an IP and/or port directly, without a domain name. In this case, the IP address would go to the domain field. If the URL contains a literal IPv6 address enclosed by [ and ] (IETF RFC 2732), the [ and ] characters should also be captured in the domain field. keyword
url.original Unmodified original url as seen in the event source. Note that in network monitoring, the observed URL may be a full URL, whereas in access logs, the URL is often just represented as a path. This field is meant to represent the URL as it was observed, complete or not. wildcard
url.original.text Multi-field of url.original. match_only_text
url.path Path of the request, such as "/search". wildcard
url.port Port of the request, such as 443. long
url.query The query field describes the query string of the request, such as "q=elasticsearch". The ? is excluded from the query string. If a URL contains no ?, there is no query field. If there is a ? but no query, the query field exists with an empty string. The exists query can be used to differentiate between the two cases. keyword
url.scheme Scheme of the request, such as "https". Note: The : is not part of the scheme. keyword
user_agent.device.name Name of the device. keyword
user_agent.name Name of the user agent. keyword
user_agent.original Unparsed user_agent string. keyword
user_agent.original.text Multi-field of user_agent.original. match_only_text
user_agent.version Version of the user agent. keyword
