Hi I'm trying to figure out what's the unit for disk performance graphs. I have checked the threshold for average disk queue length and it's 50. But when i check the performance graph for disk queue length, the values are between 0.01 and 0.14. This makes me really confused about what the figure actually represent in the performance graphs. Is it in seconds or in miliseconds? And what about the performance graphs for \Logical Disk(*)\Avg. Disk sec/Read or \Logical Disk(*)\Avg. Disk sec/Write? The values for these graphs are normally between 0 and 0.2 but I do see a spike of as large as 2000. Is this 2000 represent 2000 seconds or 2000 miliseconds? Thanks Winnie
