zabbix监控docker容器状态【推荐】

(编辑:jimmy 日期: 2024/11/28 浏览:3 次 )

前言:前段时间在部署zabbix,有个需求就是需要监控容器的状态 也就是cpu 内存 io的占用,于是就自己写了一个脚本,以及模板,在这里分享一下 嘿嘿 : )

废话我也就不多说,直接开始

首选,zabbix_agentd 配置  vim /usr/local/zabbix/etc/zabbix_agentd.conf

UserParameter=docker.discovery,/usr/local/zabbix/script/docker.py
UserParameter=docker.[*],/usr/local/zabbix/script/docker.py $1 $2

下面是docker.py 脚本,采用自动发现规则来发现容器,然后指定容器获取状态信息

#!/usr/bin/python
import sys
import os
import json
def discover():
 d = {}
 d['data'] = []
 with os.popen("docker ps -a --format {{.Names}}") as pipe:
  for line in pipe:
   info = {}
   info['{#CONTAINERNAME}'] = line.replace("\n","")
   d['data'].append(info)
 print json.dumps(d)
def status(name,action):
 if action == "ping":
  cmd = 'docker inspect --format="{{.State.Running}}" %s' %name
  result = os.popen(cmd).read().replace("\n","")
  if result == "true":
   print 1
  else:
   print 0
 else:
  cmd = 'docker stats %s --no-stream --format "{{.%s}}"' % (name,action)
  result = os.popen(cmd).read().replace("\n","")
  if "%" in result:
   print float(result.replace("%",""))
  else:
   print result
if __name__ == '__main__':
  try:
    name, action = sys.argv[1], sys.argv[2]
    status(name,action)
  except IndexError:
    discover()

这里说一下自动发现规则的坑。。。我被坑了好久才找出来.....一是必须返回json格式内容,二是 info['{#CONTAINERNAME}' ]  这个key一定要这么写{#CONTAINERNAME}......

返回结果如下,一定要是这样的层级关系....

{"data": [{"{#CONTAINERNAME}": "node-3"}, {"{#CONTAINERNAME}": "node-2"}, {"{#CONTAINERNAME}": "node-1"}, {"{#CONTAINERNAME}": "web"}, {"{#CONTAINERNAME}": "cadvisor"}, {"{#CONTAINERNAME}": "updatol"}, {"{#CONTAINERNAME}": "research"}, {"{#CONTAINERNAME}": "services"}, {"{#CONTAINERNAME}": "data"}, {"{#CONTAINERNAME}": "rabbitmq"}, {"{#CONTAINERNAME}": "redis"}, {"{#CONTAINERNAME}": "mysql"}, {"{#CONTAINERNAME}": "ssdb"}]}

另外那个函数的很简单了,就是调用docker 命令在获取数据的。

自动发现规则呢 也就是这样

只监控的这几个状态,以及还有一个触发器就是ping 来检测当前这个容器状态是否运行,如果不是就报警。

修改Zabbix_agentd 配置,docker.py脚本放在指定路径下,不要忘了给权限,导入模板,能获取数据就没问题。获取不了的,可以zabbix_get 来调试 找到问题出在哪去解决。
