Question:

Can 'Top Layer AppSwitch' log files be analyzed?

Reply:

The 'Top Layer AppSwitch' device has the ability to generate log files in the format called WELF (WebTrends Enhanced Log Format).  The log file must be in this format for Firewall Suite or Security Reporting Center to properly run analysis. A sample of the WELF format is provided below:

id=firewall time="2003-07-01 06:30:09" fw=192.168.1.1 pri=6 proto=http src=192.168.1.1 dst=10.1.1.1 dstname=domain.com arg=/brand/images/logo_pimg.gif op=GET result=304 rcvd=1036
id=firewall time="2003-07-01 06:30:09" fw=192.168.1.1 pri=6 proto=http src=192.168.1.1 dst=10.1.1.1 dstname=domain.com arg=/transparent.gif op=GET result 0 sent=546
