The External Secrets Operator exposes its Prometheus metrics in the /metrics path. To enable it, set the serviceMonitor.enabled Helm flag to true. In addition you can also set webhook.serviceMonitor.enabled=true and certController.serviceMonitor.enabled=true to create ServiceMonitor resources for the other components.

If you are using a different monitoring tool that also needs a /metrics endpoint, you can set the metrics.service.enabled Helm flag to true. In addition you can also set webhook.metrics.service.enabled and certController.metrics.service.enabled to scrape the other components.

The Operator has the metrics inherited from Kubebuilder plus some custom metrics with the externalsecret prefix.
