/**
*
* You can use Amazon CloudWatch Logs to monitor, store, and access your log files from EC2 instances, CloudTrail, and
* other sources. You can then retrieve the associated log data from CloudWatch Logs using the CloudWatch console.
* Alternatively, you can use CloudWatch Logs commands in the Amazon Web Services 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.
* Then, it can 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"). You can also 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 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 earlier than this setting are automatically deleted. The CloudWatch
* Logs agent helps 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.
