这里的设备需要每天监测两次存活状态,就使用了脚本来做,之前用shell做了一个,实现的功能是使用Ping命令检测服务器存活,不在线会将不在线的服务器及IP通过邮件发送提醒,现在在学习python,改了一个python版本。需要检测的主机我存储在/scrip/host中,格式为:

HOST  IP


好了,废话少说,上脚本:

#coding=utf-8

import subprocess

import os,time,sys,re

import smtplib

from email.mime.text import MIMEText

from email.mime.multipart import MIMEMultipart

server=smtplib.SMTP('smtp.126.com')

start_Time=time.strftime('%Y-%m-%d %H:%M:%S',time.localtime(time.time()))

mj=open('/scrip/host','r')

mi=open('/scrip/text','w')

mihost=mj.readlines()

mj.close()

online=[]

i=0

for i in range(len(mihost)):

   host=mihost[i][0:14].strip()

   ip=mihost[i][14:].strip()

   p = subprocess.Popen(["ping -c 1 -i 0.2 -W 3 "+ ip],

                           stdin = subprocess.PIPE,

                           stdout = subprocess.PIPE,

                           stderr = subprocess.PIPE,

                           shell = True)

   out = p.stdout.read()

   regex = re.compile("time=\d*", re.IGNORECASE | re.MULTILINE)

   if len(regex.findall(out)) > 0:

         online.append(host)

   else:

       fail_host =host + ' \t'+ ip

       mi.write(fail_host)

       mi.write('\n')

mi.close()

fail=open('/scrip/text','r')

number=fail.readlines()

fail_host=''.join(number)

context = 'Scan Time:' + '\t '*2 +' ' *3 + start_Time +'\n'+ 'Not Online Devices:' +'\t'+ repr(len(number)) +'\n'+ '\n' +'HOST' + ' '*12 + 'I P'  + '\n' + fail_host

msg = MIMEMultipart('alternative')

msg['Subject'] = 'Not Online Device'

part = MIMEText(context, 'plain', 'utf-8')

msg.attach(part)

server=smtplib.SMTP('smtp.126.com')

server.login("邮箱用户名","邮箱密码")

maillist=['接收邮箱',]

server.sendmail("发送邮箱地址",maillist,msg.as_string())


运行的结果:
