// 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.
