Prometheus

Nexus Repository may export metrics in Prometheus format to monitor your instance. Once Prometheus is running, verify connectivity between Prometheus and Nexus Repository at http://your-prometheus-server/targets. Prometheus may be used as a datasource for another tool like Grafana or Elastic.

See Prometheus documentation

For versions before 3.81, the Prometheus metrics endpoint is:

/service/metrics/prometheus

Starting from version 3.81 and later, the endpoint has been updated to:

/service/rest/metrics/prometheus

Uses the nx-metrics-all privilege to access the endpoint.
