Amazon ECS CloudWatch Container Insights

CloudWatch Container Insights collects, aggregates, and summarizes metrics and logs from your containerized applications and microservices. The metrics include utilization for resources such as CPU, memory, disk, and network. Network metrics are only available for tasks that use the bridge network mode. The metrics are available in CloudWatch automatic dashboards. For a full list of Amazon ECS Container Insights metrics, see Amazon ECS Container Insights Metrics in the Amazon CloudWatch User Guide.

Operational data is collected as performance log events. These are entries that use a structured JSON schema that enables high-cardinality data to be ingested and stored at scale. From this data, CloudWatch creates higher-level aggregated metrics at the cluster and service level as CloudWatch metrics. For more information, see Container Insights Structured Logs for Amazon ECS in the Amazon CloudWatch User Guide.

Important

CloudWatch Container Insights are provided at an additional cost. For information about the default monitoring metrics that are provided at no additional cost, see Amazon ECS CloudWatch Metrics.

Working With Container Insights-Enabled Clusters

Container Insights can be enabled for all new clusters created by opting in to the containerInsights account setting, on individual clusters by enabling it using the cluster settings during cluster creation, or on existing clusters by using the UpdateClusterSettings API.

Opting in to the containerInsights account setting can be done with both the Amazon ECS console and the AWS CLI. You must be running version 1.16.200 or later of the AWS CLI to use this feature. For more information on creating Amazon ECS clusters, see Creating a Cluster.

Important

For clusters containing tasks or services using the EC2 launch type, your container instances must be running version 1.29.0 or later of the Amazon ECS agent. For more information, see Amazon ECS Container Agent Versions.

To opt in all IAM users or roles on your account to Container Insights-enabled clusters using the console

  1. As the root user of the account, open the Amazon ECS console at https://console.aws.amazon.com/ecs/.

  2. In the navigation bar at the top of the screen, select the Region for which to opt in to Container Insights-enabled clusters.

  3. From the dashboard, choose Account Settings.

  4. For IAM user or role, ensure your root user or container instance IAM role is selected.

  5. For Container Insights, select the check box. Choose Save once finished.

    Important

    IAM users and IAM roles need the ecs:PutAccountSetting permission to perform this action.

  6. On the confirmation screen, choose Confirm to save the selection.

To opt in all IAM users or roles on your account to Container Insights-enabled clusters using the command line

Any user on an account can use one of the following commands to modify the default account setting for all IAM users or roles on your account. These changes apply to the entire AWS account unless an IAM user or role explicitly overrides these settings for themselves.

  • put-account-setting-default (AWS CLI) 

    aws ecs put-account-setting-default --name containerInsights --value enabled --region us-east-1

  • Write-ECSAccountSettingDefault (AWS Tools for Windows PowerShell) 

    Write-ECSAccountSettingDefault -Name containerInsights -Value enabled -Region us-east-1 -Force

To opt in an IAM user or container instance IAM role to Container Insights-enabled clusters as the root user using the command line

The root user on an account can use one of the following commands and specify the ARN of the principal IAM user or container instance IAM role in the request to modify the account settings.

  • put-account-setting (AWS CLI)

    The following example is for modifying the account setting of a specific IAM user: 

    aws ecs put-account-setting --name containerInsights --value enabled --principal-arn arn:aws:iam::aws_account_id:user/userName --region us-east-1

  • Write-ECSAccountSetting (AWS Tools for Windows PowerShell)

    The following example is for modifying the account setting of a specific IAM user: 

    Write-ECSAccountSetting -Name containerInsights -Value enabled -PrincipalArn arn:aws:iam::aws_account_id:user/userName -Region us-east-1 -Force

To update the settings for an existing cluster using the command line

Use one of the following commands to update the setting for a cluster.

  • update-cluster-settings (AWS CLI) 

    aws ecs update-cluster-settings --cluster cluster_name_or_arn --settings name=containerInsights,value=enabled|disabled --region us-east-1
