[Nagios-users] NRPE: Command 'check_disk' not defined

[Jonathan M. <jm...@wh...>]

I've been staring at this for a long time, likely pilot error, but maybe 
someone has suggestions or sees something I don't...thanks.

Nagios server version 2.8, (OS debian)
Nagios plugin version 1.4.7 (Red Hat Enterprise Linux WS release 4)
NRPE version 2.7.1

other plugins work (check_swap, check_load)

On nagios server:

/usr/local/nagios/etc/checkcommands.cfg

<-snip->

# check_disk
define command{
	command_name    check_disk
         command_line    $USER1$/check_nrpe -H $HOSTADDRESS$ -c check_disk
         }

<-snip->

On the machine I'm trying to monitor, the one running nrpe 2.7.1 with 
the Nagios plugin version 1.4.7 (Red Hat Enterprise Linux WS release 4), 
in /usr/local/nagios/libexec/etc/nrpe.cfg:

[root@paleo etc]# ls -la
total 28
drwxr-xr-x  2 nagios nagios 4096 May 30 17:03 .
drwxr-xr-x  6 nagios nagios 4096 May 30 17:13 ..
-rwxr-xr-x  1 nagios nagios 7536 May 30 17:03 nrpe.cfg

<-snip->

command[check_disk]=/usr/local/nagios/libexec/check_disk -w 20 -c 10 -p 
/dev/sda5

<-snip->

when I test it from the server "nagios" it works fine:

root@nagios:/usr/local/nagios/libexec# ./check_nrpe -H paleo -c check_disk
DISK OK - free space: / 201921 MB (93% inode=99%);| 
/=14918MB;228424;228434;0;22 8444

on the system running nrpe "paleo":

[root@paleo etc]# /usr/local/nagios/libexec/check_disk -w 20 -c 10 -p 
/dev/sda5
DISK OK - free space: / 201921 MB (93% inode=99%);| 
/=14918MB;228424;228434;0;228444

If NRPE, Command 'check_disk' not defined as the web interface reports, 
then where should it be defined? I thought I needed to define the 
command in the checkcommands.cfg on the server, then define the command 
on the client that is running nrpe daemon.

thanks for any ideas,

Jonathan Murray
