[Nagiosplug-help] odd nrpe and check_disk issue

[Rudy Montemayor]

Tom,
 
I not sure if you have gotten any feedback on your problem/question, but
try doing "/usr/local/nagios/libexec/check_disk --help"; this will maybe
show you where you may be going wrong. Also what does your
"check_command" in the service definition look like for checking /var on
hosta in your services.cfg file and then verify that command name in
your checkcommands.cfg file.
 
If I'm reading your email correctly it appears that you have hard coded
the "80 90 /var" into the nrpe.cfg file in hosta, usually these are
arguments that are passed to it so that the same command can be used for
other filesystems (/opt, /usr, etc.). 
 
Usage: check_disk -w limit -c limit [-p path]
 
The "limit" can be either in kilobytes or in percentage (%). So if you
want Warning at 80% full and Critical at 90% full the command would look
like:
 
check_disk -w 20% -c 10% -p /var
 
I hope some of this helps.
 
Rudy

Subject: [Nagiosplug-help] odd nrpe and check_disk issue


Hello,
 
I have a really odd one here.  I can't get the status of a check_disk
from a remote host. The commands seem to work with I run them manually
but Nagios can't seem to make out that response from the remote host.
 
Facts:
1.	I can manually run check_disk on my client box(hosta) to get an
answer 
[root at hosta]# /usr/local/nagios/libexec/check_disk 80 90 /var
DISK OK - [6142028 kB (73%) free on /dev/sdb1]
2.	manually run check_nrpe on my Nagios server(hostb) as Nagios
user and successfully retrieve a responsys from hosta 
[nagios at hostb]# /usr/local/nagios/libexec/check_nrpe hosta -c
check_disk1
DISK OK [4490880 kB (53%) free on /dev/sdb1]
3.	both my check_nrpe and nrpe are: 
Version: 1.5
Last Modified: 06-03-2002
License: GPL
4.	command in my nrpe.cfg:
command[check_disk1]=/usr/local/nagios/libexec/check_disk 80 90 /var 
 
Issue:
1.	Nagios Service Details page shows "Unable to read output" 
2.	I want Nagios to be able to check disk space on the remote hosts

 
 
What I have done so far to try to resolve this without success:
1.	I have tried changing the syntax of the check_disk command to 
command[check_disk1]=/usr/local/nagios/libexec/check_disk -w 20 -c 10 -p
/var
2.	check permission of user on server and remote host running
check_nrpe and nrpe 
 
 
Has anymore experience with this?  
 
Thanks in advance for your help.
Tom
