python插件做nagios发报警邮件

Ps: 完美的解决了python传入参数带有回车换行符,不换行问题。修改本文时间:2010年12月21号,脚本有变动·nagios commands.cfg无需修改·用了此版本·就解决了不用去读文本方式。

安装好nagios后,一直利用nagios服务器上的sendmail服务器去发邮件,修改配置文件可以伪造别的邮件地址发邮件,但是一直会被邮局视为垃圾邮件,我把email地址加在了QQ上,好处是一来邮件QQ右下角会弹提示。工作时间会第一时间知道服务器出状况(手机短信暂时不提),但是如果是垃圾邮件,QQ不会提醒的,当然可以在QQ邮箱把其添加为信任邮局,可以避免。我就不那么浪费时间了。自己写一个发邮件的插件来替换掉本机的sendmail服务,可以为服务器节省资源,大家也知道启动sendmail服务稍稍费点时间,如果主机名没有设置好的话sendmail服务会启动很久才能起来的哦。废话不多说了,发源代码。

import smtplib
import string

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')        #以‘\n’字符切割字符串,分割后的字符串python就不会在加\
       MESSAGE = '\n'.join(MESSAGE)          #在每个字符串后加 '\n' 字符,这样python 就会认为字符'\n'是换行符

#smtp HOST
HOST = "smtp.126.com"               #改为你的邮局SMTP 主机地址
#smtp port
PORT = "25"                               #改为你的邮局的SMTP 端口
#FROM mail user
USER = 'eric'                              # 改为你的邮箱用户名
#FROM mail password
PASSWD = '123456'                    # 改为你的邮箱密码
#FROM EMAIL
FROM = "yangzi2008@126.com"    # 改为你的邮箱 email

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"

使用方法:
只给一个用户发:

nagios $> ./sendmail -t 'eric@nginxs.com' -s 'hello eric' -m 'hello eric,this is sendmail test!

给多个用户发:

./sendmail -t 'eric@nginxs.com,yangzi@nginxs.com,zhangsan@nginxs.com' -s 'hello eric' -m 'hello eric,this is sendmail test!

如果利用在nagios 上修改 commands.cfg
# 还为测试·马上就测试。怕的是换行符有问题·

nagios $> vim /usr/local/nagios/etc/objects/commands.cfg
define command{
        command_name    notify-host-by-email
        command_line    $USER1$/sendmail -t $CONTACTEMAIL$ -s "** $NOTIFICATIONTYPE$ Host Alert: $HOSTNAME$ is $HOSTSTATE$ **"  -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    $USER1$/sendmail -t  $CONTACTEMAIL$ -s "** $NOTIFICATIONTYPE$ Service Alert: $HOSTALIAS$/$SERVICEDESC$ is $SERVICESTATE$ **"  -m  "***** Nagios *****\n\nNotification Type: $NOTIFICATIONTYPE$\n\nService: $SERVICEDESC$\nHost: $HOSTALIAS$\nAddress: $HOSTADDRESS$\nState: $SERVICESTATE$\n\nDate/Time: $LONGDATETIME$\n\nAdditional Info:\n\n$SERVICEOUTPUT$"
        }

有图有真相:
