這篇文章主要為大家展示了“zabbix如何監(jiān)控docker容器狀態(tài)”，內容簡而易懂，條理清晰，希望能夠幫助大家解決疑惑，下面讓小編帶領大家一起研究并學習一下“zabbix如何監(jiān)控docker容器狀態(tài)”這篇文章吧。
首選，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 腳本，采用自動發(fā)現規(guī)則來發(fā)現容器，然后指定容器獲取狀態(tài)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()這里說一下自動發(fā)現規(guī)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(fā)現規(guī)則呢 也就是這樣
只監(jiān)控的這幾個狀態(tài)，以及還有一個觸發(fā)器就是ping 來檢測當前這個容器狀態(tài)是否運行，如果不是就報警。

</zabbix_export>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。
