Monitoring

General

The monitoring endpoints do not go through authorization checks. Also they are not restricted to localhost.

web application

/metrics/prometheus serves metrics in the Prometheus format. If the web application is running on https://foo.bar/source/ then the URL for the metrics will be https://foo.bar/source/metrics/prometheus

Insert this snippet into /etc/prometheus/prometheus.yml:

  - job_name: opengrok

    metrics_path: '/source/metrics/prometheus'
    static_configs:
      # replace localhost with actual server name
      - targets: ['localhost:8080']

and reload the Prometheus configuration. The web application metrics will become available.

Notable metrics start with jvm and authorization.
