Load Testing Log File Columns

Hello,

I was hoping someone could help me identify the columns that are in the load test log file. I have the following record printing out:

Mon May 20 11:59:11 EDT 2013,25,245,0,0,0.0,0,0,0.0,0,0,0,0,Interval

The columns that I can identify are as follows:
Date Time Stamp
Thread Count
Elapsed Time
Min
Max
Avg
Last
Count
TPS
Bytes
BPS
Errors
?
?

The last column of Interval or Finished is probably execution state or something like that.

I can not seem to find any details as to what the inidividual columns are. Help would be appreciated.

Thanks!
