I've got a server that I'm using the new Performance Counter ability on to watch the disk queue length. APM is correctly polling the value, but it doesn't seem to keep historicals so that I can graph them and look at the queue length through the day.
Does anyone have an idea how to make that happen? I have probably missed a step somewhere, but so far I've had no luck. Here's a shot of the the value I'd like to have historicals on:

Thanks,
