How to use check_disk on remote

i want to check disk in my remote pc. someone told me to use check_nrpe but the problem is i don’t know how to use check_nrpe? where i can find it?
how can i run it?

can anyone give a sample command how to run it or to check usage via remote?

Take note that all of our server dont use snmp. SNMP is closed!!!

Get nrpe, and read the installation instructions that come with it. It gives sample cfgs, etc.
