iis6 - logman - ETL file layout and add Request ID

As output of logman command is created ETL file.

What is the meaning of each column there?
Can I add Request Id there?

Commands that I run:
logman start W3wpTrace -p "IIS: WWW Server" -ets -o c:\W3wpTrace_server.etl
logman stop W3wpTrace -ets
tracerpt  c:\W3wpTrace_server.etl -o c:\W3wpTrace_server.csv /y
