prometheus 監控 kubernetes tomcat

kubernetes tomcat說明１：kubernetes環境搭建好了，沒有就看這個
說明２：基於grafana-kubernetes-app監控tomcat我的另一文章
說明３：對於docker容器開啟tomcat監控看完一、配置環境看完就可以了
說明２：基於grafana-kubernetes-app監控tomcat我的另一文章
說明３：對於docker容器開啟tomcat監控看完一、配置環境看完就可以了
１、添加prometheus.yaml配置(在末尾就可以了)
- job_name: ‘tomcat-pods‘ kubernetes_sd_configs: - role: pod relabel_configs: - source_labels: [__meta_kubernetes_namespace] regex: tomcat action: keep - source_labels: [__meta_kubernetes_pod_container_port_number] regex: 1234 action: keep - source_labels: [__meta_kubernetes_pod_name] action: replace target_label: kubernetes_pod_name
２、tomcat模板
cat ll-tomcat.json
