Nagios 邮件报警脚本

一.python邮件发送脚本 1.linux服务器发送邮件，许多人会直接用mail命令发送，虽然可以发送成功，但是许多都会被互联网邮箱当初垃圾邮件处理

2.mutt和msmtp相关于linux下的邮件客户端，和windows上的outlook,foxmail之类有点类似 3.安装mutt和msmtp虽然可以，但是通过python脚本也可以代替，如下 Ubuntu@ubuntu:/etc/nagios3/scripts$ cat sendmail #!/usr/bin/python import smtplib import string import sys import getopt

def usage():   print """sendmail is a send mail Plugins   Usage:

  sendmail [-h|--help][-t|--to][-s|--subject][-m|--message]

  Options:         --help|-h)                 print sendmail help.         --to|-t)                 Sets sendmail to email.         --subject|-s)                 Sets the mail subject.         --message|-m)                 Sets the mail body   Example:           only one to email  user         ./sendmail -t 'eric@nginxs.com' -s 'hello eric' -m 'hello eric,this is sendmail test!           many to email  user         ./sendmail -t 'eric@nginxs.com,yangzi@nginxs.com,zhangsan@nginxs.com' -s 'hello eric' -m 'hello eric,this is sendmail test!"""   sys.exit(3)

try:   options,args = getopt.getopt(sys.argv[1:],"ht:s:m:","--help --to= --subject= --message=") except getopt.GetoptError:   usage() for name,value in options:   if name in ("-h","--help"):       usage()   if name in ("-t","--to"): # accept message user       TO = value       TO = TO.split(",")   if name in ("-s","--title"):       SUBJECT = value   if name in ("-m","--message"):       MESSAGE = value       MESSAGE = MESSAGE.split('\\n')       MESSAGE = '\n'.join(MESSAGE)

#smtp HOST HOST = "smtp.126.com"      （这个是126的smtp服务域名）        #smtp port PORT = "25"                （126邮箱smtp端口号）            #FROM mail user USER = 'Czar_test'      （你注册126邮箱的用户名）                  #FROM mail password PASSWD = 'test123'      （你注册126邮箱的密码）            #FROM EMAIL FROM = "Czar_test@126.com"  （你的126邮箱地址）

try:   BODY = string.join((     "From: %s" % FROM,     "To: %s" % TO,     "Subject: %s" % SUBJECT,     "",     MESSAGE),"\r\n")

  smtp = smtplib.SMTP()   smtp.connect(HOST,PORT)   smtp.login(USER,PASSWD)   smtp.sendmail(FROM,TO,BODY)   smtp.quit() except:   print "UNKNOWN ERROR"   print "please look help"   print "./sendmail -h"

然后测试发送邮件 ubuntu@ubuntu:/etc/nagios3/scripts$ /etc/nagios3/scripts/sendmail -t "yongkang_tian@126.com" -s "Nagios Test" -m "Hello Wrold"

二.nagios命令文件里面添加代码 ubuntu@ubuntu:/etc/nagios3$ vim commands.cfg define command{       command_name    notify-host-by-email       command_line    /etc/nagios3/scripts/sendmail  -t $CONTACTEMAIL$ -s "** $NOTIFICATIONTYPE$ Host Alert: $HOSTNAME$ is $HOSTSTATE$ **" -m "%b" -m "***** Nagios *****\n\nNotification Type: $NOTIFICATIONTYPE$\nHost: $HOSTNAME$\nState: $HOSTSTATE$\nAddress: $HOSTADDRESS$\nInfo: $HOSTOUTPUT$\n\nDate/Time: $LONGDATETIME$\n"       }

define command{       command_name    notify-service-by-email       command_line    /etc/nagios3/scripts/sendmail -t $CONTACTEMAIL$ -s "** $NOTIFICATIONTYPE$ Service Alert: $HOSTALIAS$/$SERVICEDESC$ is $SERVICESTATE$ **" -m "%b" -m "***** Nagios *****\n\nNotification Type: $NOTIFICATIONTYPE$\n\nService: $SERVICEDESC$\nHost: $HOSTALIAS$\nAddress: $HOSTADDRESS$\nState: $SERVICESTATE$\n\nDate/Time: $LONGDATETIME$\n\nAdditional Info:\n\n$SERVICEOUTPUT$\n"       }
