用python监控服务器的cpu,磁盘空间,内存,超过邮件报警_Python

　　监控Linux服务器嘛，脚本逻辑基本上是用os.popen模块，然后把获取到的结果通过split切分成一个list，再拿目标list值和我阈值对比，超过就邮件报警；

　　邮件是通过Linux的mailx发出去的，可自行搜索安装该模块，关键字：“Linux使用mailx发邮件”，脚本如下：　

一、cpu ideal值，不小于20%

				?

									#!/usr/bin/python

									# -*- coding: utf-8 -*-

									import datetime

									import os

									f = os.popen('vmstat').readlines()

									cpu_ideall = str(f).split()[-3]

									if int(cpuideall) > 20:

									    mail_content = "echo 'ip:IP地址(vmstat)' | mailx -s '[Warning!]CPU ideal below 20%, please check!' 收件邮箱"

									    os.popen(mail_content)

									else:

									    pass

二、磁盘空间，不大于95%

				?

									#!/usr/bin/python

									# -*- coding: utf-8 -*-

									import datetime

									import os

									f = os.popen('df -lh').readlines()

									s = []

									s.append(str(f).split()[11].split('%')[0])

									s.append(str(f).split()[-8].split('%')[0])

									s.append(str(f).split()[-2].split('%')[0])

									print s

									i = 0

									while i < len(s):

									    if int(s[i]) > 95:

									    mail_content = "echo 'ip:ip地址(df -lh)' | mailx -s '[Warning!]Disk above 95%, please check!' 收件邮件"

									        os.popen(mail_content)

									    else:

									    pass

									    i = i + 1

三、内存利用率，不低于200

				?

									#!/usr/bin/python

									# -*- coding: utf-8 -*-

									import datetime

									import os

									f = os.popen('free -m').readlines()

									memm = str(f).split()[10]

									if int(memm) < 200:

									    mail_content = "echo 'ip:ip地址(free -m)' | mailx -s '[Warning!]MEM below 200, please check!' 收件邮箱"

									    os.popen(mail_content)

									else:

									    pass
