Monitoring OpsWorks

You can monitor your AWS OpsWorks stacks in a number of ways:

  • Using Amazon CloudWatch
  • Using Amazon CloudWatch Logs
  • Using Amazon CloudWatch Events
  • Using Amazon CloudTrail

There is also a custom monitoring page created in OpsWorks that summarizes the data and makes it easy to understand these metrics. If you are running Windows instances, the monitoring page will not display the metrics for those Windows instances. The metrics are displayed for the entire stack, but you can also concentrate on a particular layer or a particular instance.
