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 datetimeimport osf = 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 datetimeimport osf = 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 si = 0while 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:passi = i + 1

三、内存利用率，不低于200

#!/usr/bin/python# -*- coding: utf-8 -*-import datetimeimport osf = 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！
