The python script is used to send emails to nagios

Previously, the company's nagios email sending script was written using reverse CT, but there has always been a drawback that the nagios email text cannot be wrapped and can only be displayed on one line. It seems very difficult to send an alert each time. I always wanted to change it. This line feed problem was solved by using the python script this time.

To put it bluntly, use the script:

 
 

  
  
#! /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!
  
  
Failed 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 ="])
  
  
Counter t getopt. GetoptError:
  
  
Usage ()
  
  
For name, value in options:
  
  
If name in ("-h", "-- help "):
  
  
Usage ()
  
  
If name in ("-t", "-- "):
  
  
# 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" # change it to your post office smtp host address
  
  
# Smtp port
  
  
PORT = "25" # change to the smtp port of your post office
  
  
# FROM mail user
  
  
USER = 'Eric '# change to your email USER name
  
  
# FROM mail password
  
  
PASSWD = '000000' # change your email password
  
  
# FROM EMAIL
  
  
FROM = "test@163.com" # change to your 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"
 
 

Usage:

Send only to one user:

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

Send to multiple users:

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

Applied to nagios for alarm:

[Root @ master ~] # Vim/etc/nagios/objects/commands. cfg

Define command {

Command_name sort y-host-by-email

Command_line $ USER1 $/sendmail-t $ CONTACTEMAIL $-s "** $ icationicationtype $ Host Alert: $ HOSTNAME $ is $ HOSTSTATE $ ** "-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 $ USER1 $/sendmail-t $ CONTACTEMAIL $-s "** $ icationicationtype $ Service Alert: $ HOSTALIAS $/$ SERVICEDESC $ is $ SERVICESTATE $ ** "-m" ****** Nagios ***** \ n \ nNotification Type: $ icationicationtype $ \ n \ nService: $ SERVICEDESC $ \ nHost: $ HOSTALIAS $ \ nAddress: $ HOSTADDRESS $ \ nState: $ SERVICESTATE $ \ n \ nDate/Time: $ LONGDATETIME $ \ n \ nAdditional Info: \ n $ SERVICEOUTPUT $"

}

[Root @ master ~] #/Etc/init. d/nagios reload

In this way, you can.
