Amazon Elastic Compute Cloud (EC2) instance

The following example shows a component configuration in JSON format for an Amazon EC2 instance.

Important

When an Amazon EC2 instance enters a stopped state, it is removed from monitoring. When it returns to a running state, it is added to the list of Unmonitored components on the Application details page of the CloudWatch Application Insights console. If automatic monitoring of new resources is enabled for the application, the instance is added to the list of Monitored components. However, the logs and metrics are set to the default for the workload. The previous log and metrics configuration is not saved.
