Check_disk withpartition check

Nagios
1

hello
i have problem checking var partion with check_disk plugin
what i did is
in my nrpe.cfg i defined this command
command[check_diskvar]=/usr/local/nagios/libexec/check_disk -w 20 -c 10 -m /var

when i run this command from remote host i get proper output as follows
root@host [/usr/local/nagios/libexec]# ./check_disk -w 20 -c 10 -m /var
DISK OK - free space: /var 2440 MB (41%);| /var=3467MB;5886;5896;0;5906

now when i give this command in myservices.cfg as follows

#check_disk service definition
define service {
host_name remotehost address
service_description /VAR
check_command check_nrpe!check_diskvar
use generic-service
}

i get err as follows
NRPE: Command ‘check_diskvar’ not defined
what should be done.
where m i going wrong :frowning:

Have you restarted the nrpe daemon on the remote host? You have to do this each time you make changes to the nrpe.cfg

Hi
yes i tried restarting the daemon but no luch still getting the same err NRPE: Command ‘check_diskvar’ not defined
i think i am missiong out smethng.
how do i have to define the cmmd wht i have done is it right?
Thanks

how is check_nrpe defined in your check_commands.cfg?

5

#check nrpe command definition
define command{
command_name check_nrpe
command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1
}

Also when i give this cmmd from my remote host it gives me correct output

root@host [/usr/local/nagios/libexec]# ./check_disk -w 20 -c 10 -m /var
DISK OK - free space: /var 2461 MB (42%);| /var=3446MB;5886;5896;0;5906

That all looks fine. On the remote host do ps-ef |grep nrpe. Kill the nrpe dameon(s). Then restart it. Then retry the check.

Oh
yes sure
on remote host i did changes in nrpe.cfg.
Checked the syntax of check_diskvar.
when evrythng seemed ok killed nrpe and restarted the deamon.

the syantx of check_diskvar should be
command[check_diskvar]=/usr/local/nagios/libexec/check_disk -w 20 -c 10 -m /var

Thats it
Thanks
