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-8import subprocessimport os,time,sys,reimport smtplibfrom email.mime.text import MIMETextfrom email.mime.multipart import MIMEMultipartserver=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=0for 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_hostmsg = 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())
