Integrate with Datadog
You can configure Atlas to send metric data about your project to your Datadog dashboards.
Note
If you configure your Atlas project 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.
Prerequisites
Datadog integration is available only 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.
Procedure
Performance Metrics Available to Datadog
Datadog tracks the following metric data for your Atlas cluster. The metric names in parentheses are the names used in the Datadog UI. Datadog measures each metric once per minute.
Note
The clustername tag identifies the Atlas cluster associated
with the metric.
