so why do i recieved error

NRPE: Command 'check_disk' not defined what i am missing


Thank you for all your Help

please let me know if there is something else you need form me

Can you post the full syntax you are running to get that result?

Your config looks fine, either one of your commands will work (check_hda1/check_disk). What is the result if you run check_hda1? Did you restart the xinetd / nrpe service after making the changes on the client side?

thanks for the replay i am still sorta new to nagios where can i get a full syntax

1. on nagios machine i install xinetd with the plugin and NRPE but i cant do the command "service nrpe status" on Debian i can do it on XINETD i do not know if this is an issue my target machine i can do "service NRPE status" either way i restart all service from nagios to NRPE to xinetd
2. on my client side i have NRPE install i can do a "service NRPE status" i restart XINETD and NRPE
3. my server is Debian and my client is OpenSuze

DISK CRITICAL - /dev/hda1 is not accessible: No such file or directory

spyder13337 wrote:DISK CRITICAL - /dev/hda1 is not accessible: No such file or directory

Was this from running the following command?
command[check_hda1]=/usr/local/nagios/libexec/check_disk -w 20% -c 10% -p /dev/hda1 <--- this be where i select the partion to momitor for a client side

On the client machine, what is the output of df -h?

sorry for the long delay it seem to be i was using the wrong nrpe.cfg i should be using /usr/local/nagios/etc/nrpe.cfg i had success on this
