Custom notification commands...old question with new twist...

[Lawrence, Lynne]

Steve,

I am not sure that this is what you want, but I have taken advantage of the
fact that comment lines in the .cfg files are ignored to save additional
info in my config files.  For instance, I have a config file for a clustered
service where check_cluster is used to check the cluster.  Rather than
having a separate file for the cluster service defs, I mark the cluster
services with '##', and pick them up when the check command is run.  You
could do something similar by tagging comments, though it might be tedious.

  ## host1 serial_no nnn-nn-nnnn
  ## host1 location Main floor, cabinet 183
  define host {
      use              generic_host
      host_name        host1
      alias            host1
      address          ip_goes_here
  }

Here is the config I am using, as an example.  File cust01_jabber.cfg:

 
#===========================================================================
===
  # This file contains configuration for monitoring the CUST01 jabber
servers.
  # They operate as an active/passive cluster where the jabber service
should
  # be available on one or other of the servers at all times.
 
#===========================================================================
===

 
#---------------------------------------------------------------------------
---
  # Hosts defs
 
#---------------------------------------------------------------------------
---

  # the actual hosts
  define host {
      use              generic_host
      host_name        cust01-prod-jabber01
      alias            cust01-prod-jabber01
      address          ip_goes_here
  }
  define host {
      use              generic_host
      host_name        cust01-prod-jabber02
      alias            cust01-prod-jabber02
      address          ip_goes_here
  }

  # A pseudo host representing the cluster
  define host {
      use              generic_host_nocheck
      host_name        cust01-prod-jabber
      alias            cust01-prod-jabber
      address          None
  }

 
#---------------------------------------------------------------------------
---
  # Services
 
#---------------------------------------------------------------------------
---

  # No notifications if a single cust01 jabber service is not available -
  # check_cluster used to alarm if both are down.
  #
  define service {
      use                     generic-service
      host_name               cust01-prod-jabber01,cust01-prod-jabber02
      service_description     jabber
      check_command           check_jabber
      notification_options    n
  }
  define service {
      use                     generic-service
      host_name               cust01-prod-jabber
      service_description     jabber_cluster
      check_command
check_cluster_service!2!2!etc/cust01_jabber.cfg
  }

 
#---------------------------------------------------------------------------
---
  # check_cluster_service input starts with a '##'
 
#---------------------------------------------------------------------------
---

  ## cust01-prod-jabber01;jabber
  ## cust01-prod-jabber02;jabber

My cluster check command looks like this:

  #
  # Use this to check a service cluster.  The file named by $ARG3$ should
contain
  # lines beginning with '##'.  Each of these lines should contain a
  # <host>;<service> following the '##', with optional spaces in between
  #
  define command {
      command_name    check_cluster_service
      command_line    cat /usr/local/nagios/$ARG3$ | grep '^##' | sed 's/##
*//' | $USER1$/check_cluster --service /usr/local/nagios/var/status.log
$ARG1$ $ARG2$
  }
