  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

以上就是用python监控服务器的cpu,磁盘空间,内存,超过邮件报警的详细内容,更多关于python监控服务器的资料请关注其它相关文章!
