process-exporter是主要针对进程进行监控

部署

下载

wget https://github.com/ncabatoff/process-exporter/releases/download/v0.7.5/process-exporter-0.7.5.linux-amd64.tar.gz

tar xf process-exporter-0.7.5.linux-amd64.tar.gz -C /opt/process-exporter-0.7.5.linux-amd64

ln -s /opt/process-exporter-0.7.5.linux-amd64 /opt/process-exporter

准备监控模板

模板变量

•  包含原始可执行文件的基本名称，即第二个字段 /proc/<pid>/stat
• {{.ExeBase}} 包含可执行文件的basename
• {{.ExeFull}} 包含可执行文件的完全限定路径
• {{.Matches}} 映射包含应用命令行tlb所产生的所有匹配项

 [root@izx7dvghztbiorz process-exporter]# ps -ef | grep redis 
redis 771 1 0 Jun05 ? 00:45:49 /usr/bin/redis-server *:6379

{{.Comm}}	groupname="redis-server"	exe或者sh文件名称
{{.ExeBase}}	groupname="redis-server *:6379"	/
{{.ExeFull}}	groupname="/usr/bin/redis-server *:6379"	ps中的进程完成信息
{{.Username}}	groupname="redis"	使用进程所属的用户进行分组
{{.Matches}}	groupname="map[:redis]"	表示配置到关键字“redis”

 

 

监控全部进程

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

监控指定进程

process_names:
  - name: "{{.Matches}}"
    cmdline:
    - 'nginx'

  - name: "{{.Matches}}"
    cmdline:
    - 'zombie'
