在网上检索zabbix监控mongodb性能时，大部分出现的是shell脚本，且mongodb版本不一样的话，有的性能参数是没有的。该shell脚本有一个问题就是，如果我有多个监控项目的话，那么我每个监控项目都需要进行取值，这样无形中就给mongodb增加了压力，我这边方式是取值一次然后进行多个监控值推送。

一、Python脚本数据采集

#!/usr/bin/env python

import json
import sys
import socket
from pymongo import MongoClient


listparasm = [
["connections","available"],
["connections","current"],
["connections","totalCreated"],
["globalLock","activeClients","readers"],
["globalLock","activeClients","total"],
["globalLock","activeClients","writers"],
["globalLock","currentQueue","readers"],
["globalLock","currentQueue","total"],
["globalLock","currentQueue","writers"],
["mem","mappedWithJournal"],
["mem","mapped"],
["mem","resident"],
["mem","virtual"],
["metrics","document","deleted"],
["metrics","document","inserted"],
["metrics","document","returned"],
["metrics","document","updated"],
["network","bytesIn"],
["network","bytesOut"],
["network","numRequests"],
["opcounters","command"],
["opcounters","delete"],
["opcounters","getmore"],
["opcounters","insert"],
["opcounters","query"],
["opcounters","update"],
["opcountersRepl","command"],
["opcountersRepl","delete"],
["opcountersRepl","getmore"],
["opcountersRepl","insert"],
["opcountersRepl","query"],
["opcountersRepl","update"]
]


baseitem = "mongodb.status"
hostname = socket.gethostbyname(socket.getfqdn(socket.gethostname()))
file="mongostatus.txt"

# 清空文件先，避免中途取值有问题，定时任务发送上次的数据
f = open(file,'w')

try:
    mo = MongoClient('127.0.0.1', 27017, connectTimeoutMS=5000)
except Exception as e:
    print ('Can\'t connect to '+ '127.0.0.1')
    print ("ERROR:", e)
    sys.exit(1)
res = mo.admin.command('serverStatus')

for item in listparasm:
    if len(item) == 2:
        value = res[item[0]][item[1]]
    elif len(item) == 3:
        value = res[item[0]][item[1]][item[2]]
    else:
        continue
    param = ",".join(item)
    line = hostname + "  "+baseitem+"["+param+"]"+" " + str(value)
    f.write(line+"\n")

f.close()

上面的脚本中的列表项就是采集的性能监控指标项，取值后然后按规则放进一个临时文件，最后在服务器上设置一个定时任务每分钟使用zabbix_sender批量发送监控项目值到服务端 。

# check mongodb
* * * * *  python /etc/zabbix/scripts/checkmongo.py &  zabbix_sender -z 172.31.7.125 -s 172.31.44.135  -i /tmp/mongostatus.txt &>/dev/null

二、模板导入

模板就不贴上来了，直接给个地址下载把。redis 、mysql性能监控都在下面地址上
