check_cluster config

[stephen wing]

Hi Thomas
	Thanks for the reply.
In the check_service_cluster setup that you have described, what is the
variable Shared_disk$ set to because the way that I am doing this is that I
have setup a service for both server1 and server2 to search for the
following filesystem :-
/hcndata
To do this I have the nrpe daemon running on both servers and a service
running against both these servers as follows :-

define service {
host_name                      hcntest
service_description            /hcndata Free Space
check_command                  check_nrpe!check_hcndata
use                            generic-service
max_check_attempts             3
normal_check_interval          5
retry_check_interval           1
check_period                   24x7
notification_interval          60
notification_period            24x7
notification_options           w,c,r
contact_groups                 admins
}

The check_hcndata command is defined in the nrpe.cfg file on each server
which uses the check_disk command to measure the filesystem fullness.
Hope you can understand the setup that I have.

Regards
Stephen

I simply can't understand your command line.

1. Make sure you're using a recent enough Nagios-plugins version that
ships check_cluster as a core plug-in (everything in /contrib is
unsupported).

2. the command line looks like this:
  check_cluster (-s | -h) -d val1[,val2,...,valn] [-l label]
  [-w threshold] [-c threshold]

So basically you will have to pass the following arguments (assuming
$USER1$ is the path to the plugins directory):

  $USER1$/check_cluster -s -d $ARG1$,$ARG2$ -l "$ARG3$" -c 1

Then in your service check (change the "_" to spaces if you like, they
are there for line-wrapping issues):

check_service_cluster!$SERVICESTATEID:server1:Shared_disk$!$SERVICESTATEID:s
erver2:Shared_disk$!Shared_disks
