Amazon ElastiCache monitoring

Dynatrace ingests metrics for multiple preselected namespaces, including Amazon ElastiCache. 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 1.181+, as follows:

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

    • For Dynatrace Managed deployments, you can use any kind of ActiveGate.

      For role-based access (whether in a SaaS or Managed deployment), you need an Environment ActiveGate installed on an Amazon EC2 host.

  • Dynatrace version 1.182+

  • An updated AWS monitoring policy to include the additional AWS services.
    To update the AWS IAM policy, use the JSON below, containing the monitoring policy (permissions) for all supporting services.

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

You can also view metrics in the Dynatrace web UI on dashboards. There is no preset dashboard available for this service, but you can create your own dashboard.

To check the availability of preset dashboards for each AWS service, see the list below.
