Nagios email alert script

I. python mail sending script
1. Many users send emails on the linux server directly using the mail command. Although the emails can be sent successfully, many emails will be processed by the Internet mailbox.

2. mutt and msmtp are related to the mail client in linux. They are similar to outlook and foxmail on windows.
3. Although mutt and msmtp can be installed, they can be replaced by python scripts, as shown below:
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

Sys. exit (3)

Try:
Options, args = getopt. getopt (sys. argv [1:], "ht: s: m:", "-- help -- to = -- subject = -- message = ")
Counter t getopt. GetoptError:

For name, value in options:
If name in ("-h", "-- help "):

TO = value
TO = TO. split (",")
If name in ("-s", "-- title "):

MESSAGE = '\ n'. join (MESSAGE)

# Smtp HOST
HOST = "smtp.126.com" (this is the smtp service domain name of 126)
# Smtp port
PORT = "25" (126 mail smtp PORT number)
# FROM mail user
USER = 'czar _ test' (you registered the USER Name of the 126 mailbox)
# FROM mail password
PASSWD = 'test123' (the password for your registered 126 mailbox)
# FROM EMAIL
FROM = "Czar_test@126.com" (your 126 email address)

Try:
BODY = string. join ((
"From: % s" % FROM,
"To: % s" %,
"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 t:
Print "unknown error"
Print "please look help"
Print "./sendmail-h"

Then test the email sending
Ubuntu @ ubuntu:/etc/nagios3/scripts $/etc/nagios3/scripts/sendmail-t "yongkang_tian@126.com"-s "Nagios Test"-m "Hello Wrold"

2. Add code in the nagios Command File
Ubuntu @ ubuntu:/etc/nagios3 $ vim commands. cfg
Define command {
Command_name sort y-host-by-email
Command_line/etc/nagios3/scripts/sendmail-t $ CONTACTEMAIL $-s "** $ icationicationtype $ Host Alert: $ HOSTNAME $ is $ HOSTSTATE $ ** "-m" % B "-m" ****** Nagios ***** \ n \ nNotification Type: $ icationicationtype $ \ nHost: $ HOSTNAME $ \ nState: $ HOSTSTATE $ \ nAddress: $ HOSTADDRESS $ \ nInfo: $ HOSTOUTPUT $ \ n \ nDate/Time: $ LONGDATETIME $ \ n"
}

Define command {
Command_name sort y-service-by-email
Command_line/etc/nagios3/scripts/sendmail-t $ CONTACTEMAIL $-s "** $ icationicationtype $ Service Alert: $ HOSTALIAS $/$ SERVICEDESC $ is $ SERVICESTATE $ ** "-m" % B "-m" ****** Nagios ***** \ n \ nNotification Type: $ icationicationtype $ \ n \ nService: $ SERVICEDESC $ \ nHost: $ HOSTALIAS $ \ nAddress: $ HOSTADDRESS $ \ nState: $ SERVICESTATE $ \ n \ nDate/Time: $ LONGDATETIME $ \ n \ nAdditional Info: \ n $ SERVICEOUTPUT $ \ n"
