Here’s a question from the newsgroups, the answer for which may be of interest to Operations Manager 2007 administrators.

Question: I need to report on Disk Time, and can’t see this counter even under Performance reports. I see Disk Reads/Writes, but not Disk Time on one series. Even Disk Performance Analysis doesn’t contain it.

Answer: While this data could included in the Performance Report in the Opsmgr Generic report library, the data is not present in the data warehouse by default for a couple of reasons

Physical Disks are not discovered by default as of the current version of the Windows 2003 Performance Library. Start by enabling the Discover Windows Physical Disks object discovery. Once you do this, you will find disk per second read, write and transfers performance counters are tracked through monitors.

You’ll also see that a couple of these counters are not enabled by default (in particular, the disk per second read and disk per second write), and will need to be enabled via overrides. (You’ll notice that Enabled by Default is NO in the screen shot below).

Hopefully this clears up a potential point of confusion for some of you who have experienced this issue.
