zabbix监控docker容器状态【推荐】
这篇文章主要介绍了zabbix监控docker容器状态的相关资料,非常不错，具有一定的参考借鉴价值，需要的朋友可以参考下
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
1 2 | UserParameter=docker.discovery,/usr/local/zabbix/script/docker.pyUserParameter=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
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 | #!/usr/bin/pythonimport sysimport osimport jsondef 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 resultif __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....
1 | {"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。
模板如下
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70

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。
