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

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

-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.
