How do I check the resource usage for my Amazon ECS tasks and container instances?

Resolution

To view the resource usage of your Amazon ECS tasks and container instances, complete the following steps:

1. Open the Amazon CloudWatch console.
2. In the navigation pane, under Logs, choose Logs insights.
3. Select your log group.
   Note: Log groups for Amazon ECS use the /aws/ecs/containerinsights/cluster-name/performance naming convention.
4. In the date range filter, select your time frame.
5. For Query, enter the following query:

   fields @timestamp, @log, @logStream, @message
   | filter ispresent(TaskId) and TaskId like /task-id/ and Type = "Container" and ContainerName = "container-name"
   | display TaskId, ContainerName, CpuUtilized, MemoryUtilized

   Note: Replace task-id with your task ID and container-name with your container instance name.

Now, you can view the CPU and memory utilization for your Amazon ECS tasks and container instances. To save this data view, create a custom metric filter.
