See Amazon ECS lifecycle events within Container Insights

You can view Amazon ECS lifecycle events within the Container Insights console. This helps you correlate your container metrics, logs, and events in a single view to give you a more complete operational visibility.

The events include container instance state change events, task state change events, and service action events. They are automatically sent by Amazon ECS to Amazon EventBridge and are also collected in CloudWatch in event log format. For more information about these events, see Amazon ECS events.

Standard Container Insights pricing applies for Amazon ECS Lifecycle events. For more information, see Amazon CloudWatch Pricing.

To configure the table of lifecycle events and create rules for a cluster, you must have the events:PutRule, events:PutTargets, and logs:CreateLogGroup permissions. You must also make sure that there is a resource policy that enables EventBridge to create the log stream and send logs to CloudWatch Logs. If this resource policy doesn't exist, you can enter the following command to create it:

aws --region region logs put-resource-policy --policy-name 'EventBridgeCloudWatchLogs' --policy-document '{ "Statement": [ { "Action": [ "logs:CreateLogStream", "logs:PutLogEvents" ], "Effect": "Allow", "Principal": { "Service": ["", ""] }, "Resource": "arn:aws:logs:region:account-id:log-group:/aws/events/ecs/containerinsights/*:*", "Sid": "TrustEventBridgeToStoreECSLifecycleLogEvents" } ], "Version": "2012-10-17" }'

You can use the following command to check whether you already have this policy, and to confirm that attaching it worked correctly.

aws logs describe-resource-policies --region region --output json

To view the table of lifecycle events, you must have the events:DescribeRule, events:ListTargetsByRule, and logs:DescribeLogGroups permissions.

To view Amazon ECS lifecycle events in the CloudWatch Container Insights console
