使用jenkins exporter 監控jenkins 構建任務

jenkins 提供了rest api，我們可以基於rest api 暴露prometheus metrics，社區已經有了好多
開源的實現了，使用起來也比較方便，以下集成幾個進行簡單的測試

環境准備

• docker-compose 文件

 

version: "3"

services: 

    jenkins: 

      image: jenkins/jenkins:lts-slim

      ports:

      - "8080:8080"

    jenkins-exporter2:

      image: tboerger/jenkins-exporter

      command: -jenkins.address=http://jenkins:8080 -jenkins.password=dalong -jenkins.username=admin

      ports:

      - "9103:9103"

    jenkins-exporter3:

      image: tolleiv/jenkins_exporter

      command: -j=http://jenkins:8080 --password=dalong --user=admin

      ports:

      - "9119:9118"

    jenkins-exporter:

      image: dalongrong/jenkins_exporter

      env_file:

      - .env

      ports:

      - "9118:9118"

    grafana:

      image: grafana/grafana 

      ports:

      - "3000:3000"

    prometheus:

      image: prom/prometheus

      volumes:

      - "./prometheus.yml:/etc/prometheus/prometheus.yml"

      ports:

      - "9090:9090" 

• promethesu 配置

scrape_configs:

  - job_name: jenkins

    metrics_path: /metrics

    scrape_interval: 10s

    scrape_timeout: 10s

    static_configs:

      - targets: ['jenkins-exporter:9118']

  - job_name: jenkins2

    metrics_path: /metrics

    scrape_interval: 10s

    scrape_timeout: 10s

    static_configs:

      - targets: ['jenkins-exporter2:9103']

  - job_name: jenkins3

    metrics_path: /metrics

    scrape_interval: 10s

    scrape_timeout: 10s

    static_configs:

      - targets: ['jenkins-exporter3:9118']

• 簡單說明
  包含了三個exporter tboerger/jenkins-exporter ,tolleiv/jenkins_exporter,akawork/Jenkins-exporter
  使用方法很簡單，同時也集成了一個基於docker 的jenkins，方便測試

啟動&&測試

• 啟動

docker-compose up -d

• 效果

 

 

• jenkins 任務

 

• grafana 配置
  導入github 項目的json 文件https://github.com/rongfengliang/jenkins-exporter-prometheus/blob/master/jenkins-exporter_rev1.json
  效果

 

 

說明

以上是一個簡單的集成三個exporter 進行測試，還是很方便的，可以快速的查看任務的構建的狀態
