-for setting up the sample Grafana dashboard in the [docs](https://docs.dependencytrack.org/getting-started/monitoring/#grafana-dashboard).
+Prometheus will automatically discover the API server's metrics. Grafana is configured to provision Prometheus

+on startup.
+
+To view the dashboard, visit http://localhost:3000 in your browser. The initial Grafana credentials are:
+
+* Username: `admin`
+* Password: `admin`
