Nagios email alert notification differentiation

[rellegib]

Hi,

I've setup another Nagios server and now and I want to be able differentiate between them in the email alerts I see. The email alerts I see now are nagios[nagios@domain.com]. I would like them to read something like nagios1[nagios@domain.com] and nagios2[nagios@domain.com] so I can quickly look at my email and determine which server the alerts came from.

Where would I modify this and how do I do it please?

Thanks for any help you can offer.

In the nagios object file, commands.cfg, you will find 2 notify commands - these are the commands that nagios uses to send email:

Code: Select all

define command {
       command_name                             notify-host-by-email
       command_line                             /usr/bin/printf "%b" "***** Nagios *****\n\nNotification Type: $NOTIFICATIONTYPE$\nHost: $HOSTNAME$\nState: $HOSTSTATE$\nAddress: $HOSTADDRESS$\nInfo: $HOSTOUTPUT$\n\nDate/Time: $LONGDATETIME$\n" | /bin/mail -s "** $NOTIFICATIONTYPE$ Host Alert: $HOSTNAME$ is $HOSTSTATE$ **" $CONTACTEMAIL$
}

define command {
       command_name                             notify-service-by-email
       command_line                             /usr/bin/printf "%b" "***** Nagios *****\n\nNotification Type: $NOTIFICATIONTYPE$\n\nService: $SERVICEDESC$\nHost: $HOSTALIAS$\nAddress: $HOSTADDRESS$\nState: $SERVICESTATE$\n\nDate/Time: $LONGDATETIME$\n\nAdditional Info:\n\n$SERVICEOUTPUT$" | /bin/mail -s "** $NOTIFICATIONTYPE$ Service Alert: $HOSTALIAS$/$SERVICEDESC$ is $SERVICESTATE$ **" $CONTACTEMAIL$
}

You can alter the email by adjusting the body and message of each command. For example:

Code: Select all

define command {
       command_name                             notify-host-by-email
       command_line                             /usr/bin/printf "%b" "***** Nagios Server 1 *****\n\nNotification Type: $NOTIFICATIONTYPE$\nHost: $HOSTNAME$\nState: $HOSTSTATE$\nAddress: $HOSTADDRESS$\nInfo: $HOSTOUTPUT$\n\nDate/Time: $LONGDATETIME$\n" | /bin/mail -s "** Nagios Server 1 ** ** $NOTIFICATIONTYPE$ Host Alert: $HOSTNAME$ is $HOSTSTATE$ **" $CONTACTEMAIL$
}

define command {
       command_name                             notify-service-by-email
       command_line                             /usr/bin/printf "%b" "***** Nagios Server 1 *****\n\nNotification Type: $NOTIFICATIONTYPE$\n\nService: $SERVICEDESC$\nHost: $HOSTALIAS$\nAddress: $HOSTADDRESS$\nState: $SERVICESTATE$\n\nDate/Time: $LONGDATETIME$\n\nAdditional Info:\n\n$SERVICEOUTPUT$" | /bin/mail -s "** Nagios Server 1 ** ** $NOTIFICATIONTYPE$ Service Alert: $HOSTALIAS$/$SERVICEDESC$ is $SERVICESTATE$ **" $CONTACTEMAIL$
}

Your commands may be a little bit different than those above, but you should be able to understand the necessary changes.

Check out your commands.cfg file. You should be able to define a custom command to send out emails, like so:

Code: Select all

/usr/bin/printf "%b" "***** Nagios1 *****\n\nNotification Type: $NOTIFICATIONTYPE$\nHost: $HOSTNAME$\nState: $HOSTSTATE$\nAddress: $HOSTADDRESS$\nInfo: $HOSTOUTPUT$\n\nDate/Time: $LONGDATETIME$\n" | /bin/mailx -s "** Nagios1 - $NOTIFICATIONTYPE$ Host Alert: $HOSTNAME$ is $HOSTSTATE$ **" $CONTACTEMAIL$

You can just change "Nagios1" to "Nagios2" or whatever else, and your subject will be:

** Nagios1 - $NOTIFICATIONTYPE$ Host Alert: $HOSTNAME$ is $HOSTSTATE$ **

of course with the macros being filled with their relevant values.
