Amazon EC2 Auto Scaling monitoring

For information about differences between classic services and other services, see Migrate from AWS classic (formerly "built-in") services to cloud services.

Dynatrace ingests metrics for multiple preselected namespaces, including Amazon EC2 Auto Scaling. You can view metrics for each service instance, split metrics into multiple dimensions, and create custom charts that you can pin to your dashboards.

Prerequisites

To enable monitoring for this service, you need

  • ActiveGate version 1.197+
  • For Dynatrace SaaS deployments, you need an Environment ActiveGate or a Multi-environment ActiveGate.

    For role-based access in SaaS deployment, you need an Environment ActiveGate installed on an Amazon EC2 host.

To update the AWS IAM policy, use the JSON below, containing the monitoring policy (permissions) for all supporting services.

This service monitors Amazon EC2 Auto Scaling. For this service you can see only instances with metrics.

Remember that if you have Amazon EC2 Auto Scaling service configured, you can’t have Amazon EC2 Auto Scaling (built-in) service turned on. To monitor extended metrics, you need to select Amazon EC2 Auto Scaling, otherwise Amazon EC2 Auto Scaling (built-in) will provide only a basic count of EC2 instances in the scaling group.

By default, Auto Scaling Group metrics aren't reported. To have them reported, you need to enable them in the AWS Auto Scaling Group console.

Enable monitoring

To learn how to enable service monitoring, see Enable service monitoring.

View service metrics

You can view the service metrics in your Dynatrace environment either on the custom device overview page or on your Dashboards page.

View metrics on the custom device overview page

To access the custom device overview page

  1. Go to Technologies & Processes or Technologies & Processes Classic (latest Dynatrace).
  2. Filter by service name and select the relevant custom device group.
  3. Once you select the custom device group, you're on the custom device group overview page.
  4. The custom device group overview page lists all instances (custom devices) belonging to the group. Select an instance to view the custom device overview page.

View metrics on your dashboard

After you add the service to monitoring, a preset dashboard containing all recommended metrics is automatically listed on your Dashboards page. To look for specific dashboards, filter by Preset and then by Name.

AWS presets

For existing monitored services, you might need to resave your credentials for the preset dashboard to appear on the Dashboards page. To resave your credentials, go to Settings > Cloud and virtualization > AWS, select the desired AWS instance, and then select Save.

You can't make changes on a preset dashboard directly, but you can clone and edit it. To clone a dashboard, open the browse menu (…) and select Clone.

To remove a dashboard from the dashboards page, you can hide it. To hide a dashboard, open the browse menu (…) and select Hide.

Hiding a dashboard doesn't affect other users.

Clone hide AWS
