  You can use Amazon CloudWatch Logs to monitor, store, and access your log files
  from EC2 instances, AWS CloudTrail, and other sources.

  You can then retrieve the associated log data from CloudWatch Logs using the
  CloudWatch console, CloudWatch Logs commands in the AWS CLI, CloudWatch Logs
  API, or CloudWatch Logs SDK.

  You can use CloudWatch Logs to:

    * **Monitor logs from 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
  that 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 CloudWatch metric that you
  specify.

    * **Monitor AWS CloudTrail logged events**: You can create alarms in
  CloudWatch and receive notifications of particular API activity as captured by
  CloudTrail. You can 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.
