監(jiān)控需求

接到個任務(wù)，需要監(jiān)控mongodb，我們用的mongo是分片加副本集，網(wǎng)上監(jiān)控的模板與資料太少，于是自己寫了個python腳本監(jiān)控。 滿分10分，自己對mongo的熟悉有2分吧/(ㄒoㄒ)/~~，參照自己的理解監(jiān)控了一些參數(shù)，貼出第一批監(jiān)控的數(shù)據(jù)

監(jiān)控腳本

pip install pymongo

#!/usr/bin/python
#coding=utf-8
#author OrangeLoveMilan
from pymongo import MongoClient
import json
import mylog
import sys
def login():
    '''
    登陸mongo，并執(zhí)行查詢命令

    :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():
    '''
    處理數(shù)據(jù)，轉(zhuǎn)換成便于讀寫dic格式
    :return:
    '''
    mongoStatus = login()
    del mongoStatus["localTime"]
    Status = json.loads(json.dumps(mongoStatus))
    return Status

def monitor():
    '''
    監(jiān)控的參數(shù)
    :return:
    '''
    monitorStatus = delMongoStatus()
    ##啟動時間
    uptime =  int(monitorStatus['uptime'] / 3600 / 24)

    ##物理內(nèi)存和虛擬內(nèi)存
    mem = monitorStatus['mem']
    phyMem = mem['resident']
    virMem = mem['virtual']

    ##連接數(shù)
    connections = monitorStatus['connections']
    currentCon = connections['current']
    availableCon = connections['available']
    totalCreatedCon = connections['totalCreated']

    ##操作數(shù)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()

總結(jié)

這次是監(jiān)控的mongos的狀態(tài)參數(shù)，分片的狀態(tài)和副本級的狀態(tài)下次完善時添加進(jìn)去。監(jiān)控的圖就不貼了，腳本寫的很簡單，主要運(yùn)用了python很基礎(chǔ)的字典來處理數(shù)據(jù)，給新手一個參考，一起成長
