I was wondering if there is any documentation in regards to the weight or value of what these measurements are. In other words, what am I looking at?

E.g.
AvgCPU 1,563 - Threshold or Usage?
Reads 21,918 - Is this actual calls?
Duration 4,510,204 - Is this milliseconds?
…and so on.

It would be great to have definitive guide to all of the columns.

Thanks!

This data is from a trace, so whatever these mean in traces is what they mean in CT.

For CPU, it's number of milliseconds spent using the CPU. For CT, it's summed it up.
For Reads, it's number of logical disk reads. For CT, it's summed it up.
For Duration, it's microseconds. For CT, it's summed it up.

AvgCPU is therefore the average of the CPU column.

Here's the documentation for traces: http://msdn.microsoft.com/en-us/library/aa173882(v=sql.80).aspx
