python指令碼用來nagios發送郵件

python指令碼用來nagios發送郵件

 之前公司nagios發送郵件的指令碼是用expect來寫的，但是一直有一個弊端就是nagios郵件內文不能換行，只能在一行顯示，每次警示看起來都很費勁。一直想換了它，這次用python的指令碼就解決的這個換行的問題。

 廢話少說，上指令碼：

 

  
#!/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,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"                #改為你的郵局SMTP 主機地址 
  
#smtp port 
  
PORT = "25"                          #改為你的郵局的SMTP 連接埠 
  
#FROM mail user 
  
USER = 'eric'                        # 改為你的信箱使用者名 
  
#FROM mail password 
  
PASSWD = '123456'                    # 改為你的郵箱密碼 
  
#FROM EMAIL 
  
FROM = "test@163.com"                # 改為你的郵箱 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：

只給一個使用者發：

nagios $> ./sendmail -t 'test@163.com' -s 'hello' -m 'hello,this is sendmail test!

給多個使用者發：

./sendmail -t ' test@163.com,test02@163.com' -s 'hello' -m 'hello,this is sendmail test!

應用到nagios上，用來警示：

[root@master ~]# vim /etc/nagios/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$SERVICEOUTPUT$"

       }

[root@master ~]# /etc/init.d/nagios reload

這樣就可以了。
