Right now there doesn't seem to be a very good way to alert on I/O utilization on Windows servers.  It seems like the only collected metrics related to I/O for my windows server is Disk Idle/Busy Percentage.  Unfortunately this metric does not support creating thresholds that can alert by looking at the value over multiple polling periods.  I can only create alerts that look at the Disk Busy Percentage for the last poll which is not really useful as it is much too noisy. Can this be added?
