add a new service with name “D:\ Drive Space” and pass the D drive to the -l parameter of check_nt command as shown below. So, the check_command should be check_nt!USEDDISKSPACE! -l {drive-letter-to-be-monitored} -w 80 -c 90
define service{
use generic-service
host_name remote-windows-host
service_description D:\ Drive Space
check_command check_nt!USEDDISKSPACE!-l d -w 80 -c 90
}
Repeat the same service, to monitor other drives by changing the value of -l accordingly.
