it works

If I can spare you some time, in order to make this plugin work with NCPA, you have to get a version of rstcli.exe that is compatible with your version of Intel RST, you can test this by running rstcli.exe in a command prompt.
Once you get this done, try running this command on nagios :
./check_ncpa.py -H hostIpAddress -P 5693 -t yourToken -M ‘plugins/check_intel_rst.exe’ -a ‘path=pathInWichYouStoredTheExecutablerstcli.exe’

If it shows some results then you can edit your service file.
