zabbix自發現即時監控docker容器及容器中各個服務的狀態線上業務展示

標籤：operator   delay   ado   print   open   sys.argv   dock   user   $2   

本文從開始到監控docker容器狀態分為三部分
1.查看自己的環境變數以及自己的服務路徑
（1）jdk環境： jdk1.8

（2）zabbix版本：zabbix3.4.5
（3）zabbix指令碼存放路徑：/data/zabbix/scripts/
( 4 ) .conf檔案存放路徑：/data/zabbix/etc/zabbix_agentd.conf.d/

2.配置指令碼、key、模板
首選，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 指令碼，採用自動探索規則來發現容器，然後指定容器擷取狀態資訊：

#!/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()

這裡說一下自動探索規則的坑。。。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一定要這麼寫{#CONTAINERNAME}
返回結果如下，一定要是這樣的層級關係

{"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 命令在擷取資料的。

然後匯入模板：

3.web端操作
匯入模板後
可能有的人在這匯入模板後會出現這個問題：
zabbixGlobal regular expression " CONTAINER NAME" does not exist.

出現這個問題，證明：問題不大。
去這個地方把這個去掉

如果你要瞭解這個時什麼意思：請參考官網：zabbixRegex寫法，大體意思如下：

去管理 、一般，裡邊點開正則

自己先去瞭解這個怎麼用，去添加就好了
接下來我們看一下模板中都監控了什麼

觸發器有一個

都沒問題之後我們看一下最新資料

我們看到了各個容器狀態已經添加上去了，
到此結束，你可以向你領導交差了。
