Information

This plugin is a fork of dmeiners88 / sonarqube-prometheus-exporter, as I have seen that the repository has been stopped for a long time, I will evolve in this repository the plugin.

Features

• Configure which metrics to export

Requirements

• SonarQube 8.x

Installation

1. Download latest snapshot release
2. Drop sonar-prometheus-exporter-1.0.0-SNAPSHOT.jar into $SONARQUBE_HOME/extensions/plugins.
3. Restart the SonarQube server.

Usage

1. Configure which metrics you want to export under Administration → Configuration → General Settings → Prometheus Exporter
2. Add a scrape config to your Prometheus instance similar to this:

scrape_configs:
  - job_name: 'sonarqube'
    metrics_path: '/api/prometheus/metrics'
    static_configs:
      - targets: ['localhost:9000']

3. Alternatively, point your HTTP client to http://localhost:9000/api/prometheus/metrics

Local plugin testing

In order to test the plugin locally, a file has been created for docker-compose which starts the following docker programs:

• Sonarqube 8.9-community
• Prometheus 2.30.1
• Grafana 8.1.5

Previous requirements

The previous steps to be able to test the plugin are the following:

• Install docker and docker-compose, if they are not.
• Generate the jar file, using the following command: mvn clean package
• Make sure the volume mounted inside the docker-compose points to the correct jar filename (the one generated in the previous step).
• Launch the following command: sudo sysctl -w vm.max_map_count = 262144, this command is necessary to start the internal Elasticsearch of Sonarqube.

Test execution

To run the test, you must enter the docker folder and execute the following command: docker-compose up -d or docker compose up -d, depending on the docker-compose installation performed.

To stop the test, you must enter the docker folder and execute the following command: docker-compose down or docker compose down, depending on the docker-compose installation performed.

Access to the applications is as follows:

• Sonarqube: http://localhost:9000/projects
• Information exported by the plugin for prometheus: http://localhost:9000/api/prometheus/metrics
• Prometheus: http://localhost:9090/graph
• Grafana: http://localhost:3000/

In order to view data from Sonarqube, you can add the current project, using the command mvn sonar: sonar -Dsonar.host.url = http: // localhost: 9000 -Dsonar.login = <sonarqube user token>, it is recommended launch it at least 2 times, in this way all the data can be displayed.
