Help with "DISK UNKNOWN - free space: " error

[Deborah Martin]

Check in /var/log/messages (or wherever you are logging to) on the server that should be running check_hda1 to ensure that the nagios node is able to communicate via nrpe.

Also check you can run /usr/local/nagios/libexec/check_disk -w 20% -c 10% -p /dev/root on the nrpe node.

Is it owned by the nagios user,  does it belong to the nagios group (or whatever you’ve defined for this in nrpe.cfg)

Regards,
Deborah

Hello, I've a server with nrpe and the following commands in
/usr/local/nagios/etc/nrpe.cfg :

command[check_users]=/usr/local/nagios/libexec/check_users -w 5 -c 10
command[check_load]=/usr/local/nagios/libexec/check_load -w 15,10,5 -c
30,25,20
command[check_hda1]=/usr/local/nagios/libexec/check_disk -w 20% -c 10%
-p /dev/root
command[check_zombie_procs]=/usr/local/nagios/libexec/check_procs -w 5
-c 10 -s Z
command[check_total_procs]=/usr/local/nagios/libexec/check_procs -w 150
-c 200
command[check_mem]=/usr/local/nagios/libexec/check_mem.sh 85 95

if I exec in a console /usr/local/nagios/libexec/check_disk -w 20% -c
10% -p /dev/root i obtain the following:

DISK OK - free space: /var/named/chroot/var/run/dbus 24513 MB (52%
inode=88%);| /var/named/chroot/var/run/dbus=21787MB;39005;43881;0;48757

In the nagios server i've the following config file:

define host{
        use                     generic-host            ; Name of host
template to us
        host_name               server_name
        alias                   alas_server_name
        address                 ip_address
        icon_image base/linux40.jpg
        statusmap_image base/linux40.gd2
        }

# Check hda1
define service{
        use generic-service
        host_name server_name
        service_description Disk
        check_command check_nrpe!check_hda1
        }

But nagios report an "DISK UNKNOWN - free space: " on web interface and
the same if I do /usr/lib/nagios/plugins/check_nrpe -H ip_address -c
check_hda1

Somebody can help me?

Check the permissions on the remote server, eg can the NRPE User run the command locally.
