Help on check_disk using the -p option.

[Mukarram Syed]

Brian,
Is it possible to have multiple check_command for a
single service_description?
For example:

define service{
     service_description     Disks
     check_command        check_nrpe!check_disk1
     check_command        check_nrpe!check_disk2
    }

This is only an example, I have tried this but it only
takes the check_command for the last disk in the
check_command listing (in this case it is disk2).

I have tried other options like:
define service{
     service_description     Disks
     check_command        check_nrpe!check_disk1 \
                          check_nrpe!check_disk2
    }

But this does not work.

What you suggested is currently working, but I would
prefer to have all the disks in one
service_description.
Any suggestions would be helpful.
thanks for your help indeed.
-Mukarram.
