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:
