Exports SonarQube metrics to Prometheus.

It scrapes the SonarQube server at a configurable interval and extracts measures for all metrics on all projects on all branches.

Download the JAR file from the latest release, install a JVM, and run this:

java -XX:+UseSerialGC -Xms16M -Xmx128M -jar sonarqube-to-prometheus-*.jar

To quit, press Ctrl+C.

By default, it exposes the metrics on :8080/metrics. You have to configure at least sonarqube.token in the config, see below.

• 0: Everything is fine
• 1: Unexpected error
• 2: Config couldn't be loaded

Configuration is loaded from config.toml from the current working directory.

Most options have sane defaults, but you must set sonarqube.token!

[server]
hostname = "0.0.0.0" # Address to bind to
port = 8080 # Port to bind to
min_threads = 1 # Minimum http threads
max_threads = 8 # Maximum http threads
[sonarqube]
url = "https://localhost:9000/" # URL to SonarQube
token = "xxxxx" # SonarQube authentication token (My Account / Security) 
scrape_interval = "PT1H" # How often should SonarQube be scraped? PT1M is 1 minute, PT1H is 1 hour, etc. See https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/time/Duration.html#parse(java.lang.CharSequence)
[prometheus]
metrics_path = "/metrics" # URL to publish prometheus metrics
[projects]
include = [] # Project ids to include
exclude = [] # Project ids to exclude
[metrics]
include = [] # Metrics to include
exclude = [] # Metrics to exclude
[branches]
include = [] # Branches to include
exclude = [] # Branches to exclude

If the include list is non-empty, the project id / metric has to be in the list to be included.

Otherwise the exclude list is checked for the project id / metric.

Example:

[projects]
include = ["your.project:id"]
exclude = []

Only the project your.project:id will be scraped from SonarQube, all others are ignored.

Another example:

[projects]
include = []
exclude = ["your.project:id"]

All projects will be scraped, except the project your.project:id.

The metric type LEVEL is mapped as follows:

• OK -> 0.0
• WARN -> 1.0
• ERROR -> 2.0

Log in into your SonarQube instance and click your user icon in the top right corner. Select "My Account", switch to the "Security" tab and generate a new token.
