Error on Disk health in windows Servers

I have been trying to implement an end-to-end monitoring on all my windows servers using icinga. For some reason I am getting this error on the disk health check command. I tried going through the scripts and I figured out that the Enums are not properly being imported, but even after solving that, the error goes away, but the response is critical. It says 1 does not match the threshold value 0. Can anyone help?
