[Icecast] Log file format + Awstats

[Mike Place]

I'm trying to process Icecast2 log files with Awstats and I'm running 
into a problem which I believe may be related to an extra entry in the 
Icecast2 logfiles.

If one compares an Apache CLF log entry such as the following: 

199.125.245.200 - - [08/May/2006:12:26:00 -0600] "GET / HTTP/1.0" 200 53 
"-" "-"

to an Icecast2 log entry:

166.70.52.200 - - [08/May/2006:08:10:07 -0600] "GET /stream HTTP/1.1" 
200 13623243 "-" "RMA/1.0 (compatible; RealMedia)" 3392

one finds an additional number tacked on to the end of the Icecast log 
entry. 

Can anybody tell me what that number represents? (In the example above, 
it's 3392.)

Also, if anybody has pointers on Awstats+Icecast2, I'd love to hear 
them.

TIA,
