Output fields list and descriptions

[adrabkin]

Is there a document somewhere that explains and/or describes the output fields, either live or output files?

For example, what does "Entries" correlate to?
is Files total, just a total number of files that were accessed during the test?
what about "Files latency" vs IO Latency, what is the correlation between the two?

A document with the field descriptions would be very helpful :)
