kubesphere -prometheus 自动监控jvm

在你的service中添加这个注解，他就能自动识别

annotations:
    prometheus.io/jvm: 'true'
    prometheus.io/port: '19999'

大概的prometheus规则就是匹配所有的集群 service中 annotations包含着两条规则，然后他截取 port作为端口

你jmx端口是什么，那个port就配置成什么

prometheus.yaml

- job_name: jmx
  scrape_interval: 5s
  kubernetes_sd_configs:
  - role: endpoints
  relabel_configs:
  - source_labels: [__meta_kubernetes_service_annotation_prometheus_io_jvm]
    action: keep
    regex: true
  - source_labels: [__address__, __meta_kubernetes_service_annotation_prometheus_io_port]
    action: replace
    target_label: __address__
    regex: ([^:]+)(?::\d+)?;(\d+)
    replacement: $1:$2
  - source_labels: [__meta_kubernetes_service_name]
    action: replace
    regex: (.+)
    target_label: application
    replacement: $1
  - source_labels: [__meta_kubernetes_namespace]
    action: replace
    regex: (.+)
    target_label: namespace
  - source_labels: [__meta_kubernetes_pod_name]
    action: replace
    regex: (.+)
    target_label: pod
    replacement: $1
  - action: labelmap
    regex: __meta_kubernetes_service_label_(.+)
