Jenkins Exporter

An exporter for Jenkins Build metrics written in Golang. The program is intended to run as daemon. It fetches periodically metrics for Jenkins builds and Stages via the Jenkins API and publishes them via an HTTP endpoint in Prometheus format.

It provides the following Prometheus metrics:

  • Histograms:
    • jenkins_exporter_job_duration_seconds_bucket,
      jenkins_exporter_job_duration_seconds_sum,
      jenkins_exporter_job_duration_seconds_count
      • Labels:
        • result
        • jenkins_job: the name of the Jenkins Job
        • branch: for multibranch Jenkins Jobs, the branch name
      • type: type of recorded duration, one of:
        • blocked_time
        • buildable_time
        • building_duration
        • executing_time
        • waiting_time
    • jenkins_exporter_stage_duration_seconds_bucket,
      jenkins_exporter_stage_duration_seconds_sum,
      jenkins_exporter_stage_duration_seconds_count,
      • Labels:
        • result: result of the stage
        • stage: stage name
        • type:
          • duration
        • branch: for multibranch Jenkins Jobs, the branch name
  • Counter:
    • jenkins_exporter_errors
      Counts the number of errors the jenkins-exporter encountered when fetching information from the Jenkins API.
      • Labels:
        • type:
          • jenkins_api
          • jenkins_wfapi

By default job metrics are recorded for every finished Jenkins build. The Jenkins jobs for that builds are recorded can be limited with the --jenkins-job-whitelist command-line parameter. The duration types that are recorded can also be configured via a command-line parameter.

The exporter can also record durations of individual pipeline stages. This requires that the Pipeline Stage View Plugin is installed on the Jenkins server. Recording per stage metrics can be enabled via the -enable-build-stage-metrics command-line parameter. The -build-stage-allowlist parameter allows to specify for which jobs and stages, per-stage metrics are recorded.

All parameter can also be specified via environment variables. See ./jenkins-exporter -help for more information.
