I checked the management pack i have it seems correct although i didnt see anything for R2 so i see windows server 2008 operating system monitoring but nothing for R2 is this correct?
I also double checked my management pack and it's the latest version.
I've checked the event logs for both the SCOM management server and the cluster and can see no errors.
Only thing i havent done is the config of the management pack which i'm unsure to do, i havent chnaged any settings for the management pack such as overides etc and so the default settings should pick it up but it doesnt.
