check disks by remote

[Miguel Faria]

Hi Ian/rest of the crew,

Thanks a lot for your help. Your clues got me thinking, and I found a great
solution:

- First, you need to create and public key from the main server to another
(see instructions http://www.arches.uga.edu/~pkeck/ssh/ in case you don't
know how); 
- next you need to use the plugins check_by_ssh and check_disk and add the
following on the checkcommands.cfg:

./check_by_ssh -t 15 -l user -i ~/.ssh/id_dsa -H host -C '/check_disk -w 10%
-c 5% -p /dev/sdax'

I added on the definition and services. Restarted Nagios. It works great!!

I had asked the same question awhile back. Sean pointed me to 
"check_snmp_disk.pl". Do a search on the list for "Check diskspace on 
remote machines" to read the previous post.

It works great for myself with 'nix machines. You just have to setup 
SNMP on the hosts. Also you'll need to define a command in Nagios such as:

define command{
         command_name    snmp_disk
         command_line    $USER1$/check_snmp_disk.pl -H $HOSTADDRESS$ -C 
public -w $ARG1$ -c $ARG2$
         }

That's about all there is to it.
