前言：前段時間在部署zabbix，有個需求就是需要監控容器的狀態 也就是cpu 內存 io的占用，于是就自己寫了一個腳本，以及模板，在這里分享一下 嘿嘿 : )
廢話我也就不多說，直接開始
首選，zabbix_agentd 配置 vim /usr/local/zabbix/etc/zabbix_agentd.conf
|
1
2
|
UserParameter=docker.[*],/usr/local/zabbix/script/docker.py $1 $2 |
下面是docker.py 腳本，采用自動發現規則來發現容器，然后指定容器獲取狀態信息

#!/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() |
這里說一下自動發現規則的坑。。。我被坑了好久才找出來.....一是必須返回json格式內容，二是 info['{#CONTAINERNAME}' ] 這個key一定要這么寫{#CONTAINERNAME}......
返回結果如下，一定要是這樣的層級關系....

{"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"}]} |
另外那個函數的很簡單了，就是調用docker 命令在獲取數據的。
自動發現規則呢 也就是這樣
只監控的這幾個狀態，以及還有一個觸發器就是ping 來檢測當前這個容器狀態是否運行，如果不是就報警。
模板如下

修改Zabbix_agentd 配置，docker.py腳本放在指定路徑下，不要忘了給權限，導入模板，能獲取數據就沒問題。獲取不了的，可以zabbix_get 來調試 找到問題出在哪去解決。
