前面講了安裝jenkins exporter方式監控jenkins，但是grafana支援較少。

接下來，我們用Jenkins plugin的方式監控，這個方法部署簡單，然後grafana支援比較完整。

首先，需要安裝Jenkins，參照上一個文件完成。

1.安裝Jenkins Plugin

開啟外掛管理介面

搜尋Prometheus外掛

安裝完成重啟生效

2.檢查外掛配置

檢查配置

儲存配置

設定完成後重啟Jenkins服務，並且訪問jenkins的url檢視指標情況

訪問 http://192.168.0.107:8080/prometheus/

3. Prometheus監控Jenkins

Prometheus配置檔案/etc/prometheus/prometheus.yml，新增如下內容:scrape_configs:    - job_name: "jenkins"      metrics_path: "/prometheus/"      scheme: http      static_configs:      - targets: ['192.168.0.107:8080']這裡如果用的是tls， 用下面的配置scrape_configs:  - job_name: 'jenkins'    scheme: https # change to http if don't you have https    metrics_path: '/prometheus/'    static_configs:      - targets: ['192.168.0.107:443'] # Jenkins host and port you serve    tls_config:      insecure_skip_verify: true重啟Prometheussystemctl restart prometheus

檢查Prometheus Target

Prometheus Target

4.Grafana模板

這裡我使用模板 https://grafana.com/grafana/dashboards/9964

匯入模板

Jenkins監控

至此，完成Prometheus對Jenkins的監控。

推薦此方法。
