监控需求

接到个任务，需要监控mongodb，我们用的mongo是分片加副本集，网上监控的模板与资料太少，于是自己写了个python脚本监控。 满分10分，自己对mongo的熟悉有2分吧/(ㄒoㄒ)/~~，参照自己的理解监控了一些参数，贴出第一批监控的数据

监控脚本

pip install pymongo

#!/usr/bin/python
#coding=utf-8
#author OrangeLoveMilan
from pymongo import MongoClient
import json
import mylog
import sys
def login():
    '''
    登陆mongo，并执行查询命令

    :return:
    '''
    try:

        client = MongoClient('ip', port)
        db = client.admin
        db.authenticate("user", "pwd")
        command = db.command('serverStatus')
        return command
    except Exception,e:
        mylog.logging.error(e)
    sys.exit()

def delMongoStatus():
    '''
    处理数据，转换成便于读写dic格式
    :return:
    '''
    mongoStatus = login()
    del mongoStatus["localTime"]
    Status = json.loads(json.dumps(mongoStatus))
    return Status

def monitor():
    '''
    监控的参数
    :return:
    '''
    monitorStatus = delMongoStatus()
    ##启动时间
    uptime =  int(monitorStatus['uptime'] / 3600 / 24)

    ##物理内存和虚拟内存
    mem = monitorStatus['mem']
    phyMem = mem['resident']
    virMem = mem['virtual']

    ##连接数
    connections = monitorStatus['connections']
    currentCon = connections['current']
    availableCon = connections['available']
    totalCreatedCon = connections['totalCreated']

    ##操作数目
    opcounters = monitorStatus['opcounters']
    getmore = opcounters['getmore']
    insert = opcounters['insert']
    update = opcounters['update']
    command = opcounters['command']
    query = opcounters['query']
    delete = opcounters['delete']

    monitorDic = {'uptime':uptime,'phyMem':phyMem,'virMem':virMem,'currentCon':currentCon,'availableCon':availableCon,'totalCreatedCon':totalCreatedCon,'getmore':getmore,'insert':insert,'update':update,'command':command,'query':query,'delete':delete}
    return monitorDic


try:
    zabbix = monitor()
    for key in zabbix:
        if key == sys.argv[1]:
            print zabbix[key]


except Exception,e:
    mylog.logging.error(e)
    sys.exit()

总结

这次是监控的mongos的状态参数，分片的状态和副本级的状态下次完善时添加进去。监控的图就不贴了，脚本写的很简单，主要运用了python很基础的字典来处理数据，给新手一个参考，一起成长
