本文从开始到监控docker容器状态分为三部分 1.查看自己的环境变量以及自己的服务路径 （1）jdk环境： jdk1.8 （2）zabbix版本：zabbix3.4.5 （3）zabbix脚本存放路径：/data/zabbix/scripts/ ( 4 ) .conf文件存放路径：/data/zabbix/etc/zabbix_agentd.conf.d/

2.配置脚本、key、模板 首选，zabbix_agentd 配置 vim/data/zabbix/etc/zabbix_agentd.conf.d/docker.conf

UserParameter=docker.discovery,/data/zabbix/scripts/docker.py UserParameter=docker.[*],/data/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。

然后导入模板：模板如下：

模板下载链接：https://pan.baidu.com/share/init?surl=18Z9QIkSuLQ3sSPqSlbY2A 密码：3544 3.web端操作导入模板后可能有的人在这导入模板后会出现这个问题： zabbixGlobal regular expression " CONTAINER NAME" does not exist. 出现这个问题，证明：问题不大。去这个地方把这个去掉
