Monitoring disk usage

[Juki]

Hi Guy,

I tried all the changes as per your suggestion, however, I still come up
with the same errors as before, that is;

"NRPE: Command 'check_ora' not defined"
"NRPE: Command 'check_server1' not defined"
"NRPE: Command 'check_var' not defined"


Where else in the configuration files on the monitoring server are commands
defined?


Regards,
Juki
