It depends on the type of server and agent.
Here are some guides

thanks for the link. Do you know how I could tweak the command to alert when there is <10gb instead of a percentage of space available.
./check_nrpe -H 10.25.11.3 -c check_drivesize -a drive=C: 'warning=free<20%' 'critical=free<10%' show-all 'perf-config=*(unit:G)' detail-syntax='{${drive_or_name} ${free_pct}% free / ${size} total}' top-syntax='${status}: ${problem_list}'
Also, what is the ip for that is provided in the command?

Code: Select all
./check_nrpe -H 10.25.11.3 -c check_drivesize -a drive=C: 'warning=free<10g' 'critical=free<10g' show-all 'perf-config=*(unit:G)' detail-syntax='{${drive_or_name} ${free_pct}% free / ${size} total}' top-syntax='${status}: ${problem_list}'

The IP is the IP of your windows host

Thank you so much for your help man. What if I want to select a host group in ql for the check to run against and not just a specific ip because im I want to run it against all windows hosts in my env. Do I just take out the -h along with the ip?

You can create the command like this
Code: Select all
$USER1$/check_nrpe -H $HOSTADDRESS$ -c check_drivesize -a drive=C: 'warning=free<10g' 'critical=free<10g' show-all 'perf-config=*(unit:G)' detail-syntax='{${drive_or_name} ${free_pct}% free / ${size} total}' top-syntax='${status}: ${problem_list}'
$HOSTADDRESS$ will be replaced with the address field of each of the hosts in the host group when Nagios runs the command
