Accessing CloudWatch metrics

You can view Amazon EFS metrics for CloudWatch in several ways:

  • In the Amazon EFS console

  • In the CloudWatch console

  • Using the CloudWatch CLI

  • Using the CloudWatch API

The following procedures show you how to access the metrics using these various tools.

To view CloudWatch metrics and alarms in the Amazon EFS console

  2. Choose File systems.

  3. Choose the file system that you want to view CloudWatch metrics for.

  4. Choose Monitoring to display the File system metrics page.

    The File system metrics page displays a default set of CloudWatch metrics for the file system. Any CloudWatch alarms that you have configured also display with these metrics. For file systems that use Max I/O performance mode, the default set of metrics includes Burst Credit balance in place of Percent IO limit. You can override the default settings using the Metrics settings dialog box, accessed by opening the settings.


    The Throughput utilization (%) metric is not a CloudWatch metric; it is derived using CloudWatch metric math.
