Introduction

If you deploy SonarQube Server on Kubernetes, Prometheus metrics can be collected.

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

• The metrics exposed on the SonarQube Server 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.

See the List of Prometheus metrics for more information.

The figure below shows in a simplified way the exposition of the Prometheus metrics. Note that:

• The normal metrics are exposed at the /api/monitoring/metrics endpoint of the Web API.

• The JMX metrics are exposed at two ports, one for the metrics related to the Compute Engine (CE) process and one for the metrics related to the Web server process of SonarQube Server.

You can collect the metrics in different ways:

• For SonarQube Server’s native integration with Prometheus, you have to connect Prometheus with an observability platform, for example with Grafana. See Setting up with Prometheus server.

• For Datadog, you can use the Datadog observability platform. See Setting up with Datadog.
