Nagios notify by Google Chat (with HTTP proxy, and google apps domains)

[localzuk]

As our mail system is google apps, and therefore includes the Google Talk system, I decided to have a play with getting this working with Nagios notifications. After reading the information here about using it with Jabber, I made some changes to get it to work within a typical school network. Namely, one with a proxy server and one with a custom domain.

 

The result is below.

 

Nagios command definitions remain the same as the above link:

 

[color=#000000]# 'host-notify-by-jabber' command definition[/color]
define command{        
command_name    host-notify-by-jabber        
command_line    /usr/local/bin/notify_via_jabber $CONTACTPAGER$ "Host '$HOSTALIAS$' is $HOSTSTATE$ - Info: $HOSTOUTPUT$"        
}

# 'notify-by-jabber' command definition
define command{        
command_name    notify-by-jabber        
command_line    /usr/local/bin/notify_via_jabber $CONTACTPAGER$ "$NOTIFICATIONTYPE$ $HOSTNAME$ $SERVICEDESC$ $SERVICESTATE$ $SERVICEOUTPUT$ $LONGDATETIME$"        
}

 

The below is the modified script. This needs putting into a file wherever you normally store your plugins for nagios (and the above editing to reflect this). This file needs execute permissions applying to it for the nagios user.

To use it with your contacts in nagios, set the 'pager' value for any contacts to their google apps username (without the domain name). Also, you'll need to assign the 2 commands listed above to those users.
