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.</p> </li> <li> <p> <b>Monitor AWS CloudTrail logged events</b>: You can create alarms in CloudWatch and receive notifications of particular API activity as captured by CloudTrail.

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.</p> </li> </ul>"
