python插件做nagios发报警邮件[转]

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。

vim /usr/local/nagios/libexec/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()

       TO = value
       TO = TO.split(",")

       MESSAGE = value
       MESSAGE = MESSAGE.split('\\n')
       MESSAGE = '\n'.join(MESSAGE)

#smtp HOST
HOST = "smtp.126.com"               #改为你的邮局SMTP 主机地址
#smtp port

   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!
