python插件做nagios發報警郵件

Ps: 完美的解決了python傳入參數帶有回車換行符，不換行問題。修改本文時間：2010年12月21號，腳本有變動·nagios commands.cfg無需修改·用了此版本·就解決了不用去讀文本方式。

安裝好nagios後，一直利用nagios服務器上的sendmail服務器去發郵件，修改配置文件可以僞造別的郵件地址發郵件，但是一直會被郵局視爲垃圾郵件，我把email地址加在了QQ上，好處是一來郵件QQ右下角會彈提示。工作時間會第一時間知道服務器出狀況（手機短信暫時不提），但是如果是垃圾郵件，QQ不會提醒的，當然可以在QQ郵箱把其添加爲信任郵局，可以避免。我就不那麼浪費時間了。自己寫一個發郵件的插件來替換掉本機的sendmail服務，可以爲服務器節省資源，大家也知道啓動sendmail服務稍稍費點時間，如果主機名沒有設置好的話sendmail服務會啓動很久才能起來的哦。廢話不多說了，發源代碼。

nagios $> cat /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 '[email protected]' -s 'hello eric' -m 'hello eric,this is sendmail test!
           many to email  user
          ./sendmail -t '[email protected],[email protected],[email protected]' -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"               #改爲你的郵局SMTP 主機地址
#smtp port
PORT = "25"                               #改爲你的郵局的SMTP 端口
#FROM mail user
USER = 'eric'                              # 改爲你的郵箱用戶名
#FROM mail password
PASSWD = '123456'                    # 改爲你的郵箱密碼
#FROM EMAIL
FROM = "[email protected]"    # 改爲你的郵箱 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：
只給一個用戶發：

nagios $> ./sendmail -t '[email protected]' -s 'hello eric' -m 'hello eric,this is sendmail test!

給多個用戶發：

./sendmail -t '[email protected],[email protected],[email protected]' -s 'hello eric' -m 'hello eric,this is sendmail test!

如果利用在nagios 上修改 commands.cfg
# 還爲測試·馬上就測試。怕的是換行符有問題·

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$SERVICEOUTPUT$"
        }
