使用python 检查存活主机
这里的设备对存活状态不是很敏感，就使用了脚本来检测存活状态，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：
