check_portage version 0.1

Requirements

• Nagios 2.5
• Ruby 1.8.5

Possibly it will also work with other versions of these components, but this are the versions with which I tested.

How to setup

• Copy check_portage to /usr/nagios/libexec/ and make it owned by the nagios user. Also make it executable.
• Than you need to put the nagios user into the portage group, so it can run emerge.
• Next, you need to define a new command:

  define command {
    command_name    check_portage
    command_line    $USER1$/check_portage
  }
  

• To use the command you need to add a service definition for your host. This definition checks portage one time a day:

  define service{
    use                             generic-service
    host_name                       glotze
    service_description             Portage
    is_volatile                     0
    check_period                    24x7
    max_check_attempts              4
    normal_check_interval           1440
    retry_check_interval            1
    contact_groups                  admins
    notification_options            w,u,c,r
    notification_interval           1440
    notification_period             24x7
    check_command                   check_portage
  }
