Integrate with a Monitoring Service

You can use a third-party application to view and analyze performance metrics that Atlas collects about your cluster.

At this time, you can either build a monitoring integration using the Atlas API or integrate Atlas with Datadog.

You can build a monitoring integration using the Atlas API monitoring and logs endpoints.

You can configure Atlas to send metric data about your project to your Datadog dashboards.

Info With Circle IconCreated with Sketch.Note

If your Atlas project is configured to send alerts and events to Datadog, you do not need to follow this procedure. Atlas sends project metrics to Datadog through the same integration used to send alerts and events.

Datadog integration is only available on M10+ clusters.

To integrate Atlas with Datadog, you must have a Datadog account and a Datadog API key. Datadog grants you an API key when you first create a Datadog account.

If you do not have an existing Datadog account, you can sign up at https://app.datadoghq.com/signup.

To configure Atlas integration with Datadog:

1
  1. If it is not already displayed, select the organization that contains your desired project from the Organizations menu in the navigation bar.
  2. If it is not already displayed, select your desired project from the Projects menu in the navigation bar.
  3. Next to the Projects menu, expand the Options menu, then click Integrations.
2
  1. Click Configure for the Datadog integration card.
  2. Enter your Datadog API key in the input box.
  3. Select your API Region (United States or Europe)
  4. Click Save.

Datadog tracks the following metric data for your Atlas cluster. The metric names in parentheses are the names used in the Datadog UI . Each metric is measured once per minute.
