PingGateway

Metrics at the Prometheus Scrape Endpoint

PingGateway exposes a monitoring endpoint where Prometheus can scrape metrics in a standard Prometheus format. Learn more from the Prometheus website.

When PingGateway is set up as described in the Quick install, the Prometheus Scrape Endpoint is available at the following endpoints:

  • http://ig.example.com:8080/openig/metrics/prometheus/0.0.4

  • http://ig.example.com:8080/openig/metrics/prometheus (deprecated)

Learn to query the Prometheus Scrape Endpoint in Monitor the Prometheus Scrape Endpoint.

Some ig_jvm_* metrics depend on the JVM version and configuration. In particular, GC-related metrics depend on the garbage collector that the server uses. The GC metric names are unstable and can change even in a minor JVM release.
