Hi,
I just saw a presentation on monitoring SQL server and the person giving it had a spreadsheet showing all his stats recorded with PerfMon. One thing I noticed was that he had taken the Avg. Disk Queue Length of the Data and log Drives(fair enough). I noticed however that he had a column listing the total Avg. Disk Queue Length of the Data and Log drives. I was wondering is this total something that needs to be considered when monitoring? I would always have looked at the Avg. Disk Queue Length for each drive separately.
Cheers
Paul
