部署process-exporter

GitHub - ncabatoff/process-exporter: Prometheus exporter that mines /proc to report on selected processes

配置文件

监控所有进程

process_names:
  - name: "{{.Comm}}"
    cmdline:
    - '.+'

docker部署

docker run -d --name process-exporter --network host  --privileged -v /proc:/host/proc -v `pwd`/config:/config ncabatoff/process-exporter:0.7.10 --procfs /host/proc -config.path /config/process-exporter.yaml

给process-exporter配置servicemonitor

按需替换Endpoints中的ip

apiVersion: v1
kind: Service
metadata:
  name: xxx-process
  namespace: xxx-system
spec:
  clusterIP: None
  ports:
  - name: xxx-process
    port: 9256
    protocol: TCP
    targetPort: 9256
  sessionAffinity: None
  type: ClusterIP
status:
  loadBalancer: {}

apiVersion: v1
kind: Endpoints
