// You can use Amazon CloudWatch Logs to monitor, store, and access your log
// files from Amazon Elastic Compute Cloud (Amazon EC2) instances, Amazon CloudTrail,
// or other sources. You can then retrieve the associated log data from CloudWatch
// Logs using the Amazon CloudWatch console, the CloudWatch Logs commands in
// the AWS CLI, the CloudWatch Logs API, or the CloudWatch Logs SDK.
//
// You can use CloudWatch Logs to:
//
//    * Monitor Logs from Amazon EC2 Instances in Real-time: You can use CloudWatch
//    Logs to monitor applications and systems using log data. For example,
//    CloudWatch Logs can track the number of errors that occur in your application
//    logs and send you a notification whenever the rate of errors exceeds a
//    threshold you specify. CloudWatch Logs uses your log data for monitoring;
//    so, no code changes are required. For example, you can monitor application
//    logs for specific literal terms (such as "NullReferenceException") or
//    count the number of occurrences of a literal term at a particular position
//    in log data (such as "404" status codes in an Apache access log). When
//    the term you are searching for is found, CloudWatch Logs reports the data
//    to a Amazon CloudWatch metric that you specify.
//
//    * Monitor Amazon CloudTrail Logged Events: You can create alarms in Amazon
//    CloudWatch and receive notifications of particular API activity as captured
//    by CloudTrail and use the notification to perform troubleshooting.
//
//    * Archive Log Data: You can use CloudWatch Logs to store your log data
//    in highly durable storage. You can change the log retention setting so
//    that any log events older than this setting are automatically deleted.
//    The CloudWatch Logs agent makes it easy to quickly send both rotated and
//    non-rotated log data off of a host and into the log service. You can then
//    access the raw log data when you need it.
//The service client's operations are safe to be used concurrently.
// It is not safe to mutate any of the client's properties though.
