IIS & App pool monitoring in check_mk

I have updated the file and in the checkmk.yaml file i have updated this

C:\Program Files (x86)\checkmk\check_iis\check_iis.exe --check-apppools --perfcounter-apppools

and i created an MRPE check with this path C:\Program Files (x86)\checkmk\check_iis\check_iis.exe --check-apppools --perfcounter-apppools

but i don’t see any app pool getting monitored i am on version 1.6.0p24 and agent version is 1.6.0p18.
