ActiveGate self-monitoring metrics

Dynatrace offers a special self-monitoring category of metrics to provide observability into the operation and health of Dynatrace components and features. These metrics are available in every Dynatrace Managed and SaaS environment and can be identified by the dsfm: metric prefix.

For more information, see Self-monitoring metrics.

Following is the list of self-monitoring metrics that can be used to get insights into the operation of an ActiveGate.
