Save incoming queries to DB or text file?

Hi,
I am doing some research on p2p and would like to save incoming
queries to a DB or text file.

I am using gtk-gnutella and this already has an option to "monitor"
incoming searches via the GUI (user selectable), but this is only to
the screen.

My question is this:
- Should I look to modify the code at this point and get the output
from the screen written to a file? 
*OR*
- Should I try to get the message once it has been successfully
deflated from the TCP stream? This will get me the whole QUERY msg. 

Unfortunately I am not a very good programmer and I am more interested
in the statistical analysis!
Thanks
