Introduction to the SonarQube monitoring on Kubernetes

If you deploy SonarQube on Kubernetes, the following Prometheus metrics can be collected:

  • The metrics exposed on the SonarQube Web API’s monitoring endpoint. Results are returned in OpenMetrics text format.
  • The JMX metrics exposed by the Prometheus JMX exporter in a format understandable by Prometheus. The exposition of these metrics is disabled by default.

You can collect the metrics in different ways, such as:
