Firstly this is a great tool for a quick snapshot of how a SQL Server is doing.
I would like to know how this tool is getting is values for Seek Time - Disk Wait Times for Read and Write.
I have setup Performance Monitor to capture values on Avg Disk Sec/Read and Avg Disk Sec/Write for both Logical Disk and Physical Disk but the values are very different.
I have setup a trace and see what this tool fires at the SQL Server but there is nothing in there for these counters.
Disk Seek Time for Reads and Writes are not specific counters but calculated by summing specific wait stats and dividing by Physical Reads and Writes.
Thanks for the reply. The problem with that method of calculation is that the values graphed don't match the values recorded by the perf mon counters for avg disk sec/read and /write.
