Check-users is work but check_disk is not work

Hi There,

I’m a newbie to nagios monitoring. Just configured the monitoring server and monitoring client. While I’m checking from server to client the check_user command is working but check_disk is not working. It says the error below.


**check_disk command is not defined any where. **


Do I need to configure the check_disk command in nrpe.cfg?

Kindly help me.

Thanks in advance
