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"
      }
