SunScreen welfmt Utility

The SunScreen welfmt utility reads a SunScreen binary log file and generates an ASCII log file in WebTrends Enhanced Log Format (WELF). This allows the WebTrends Firewall Suite (WFS) to analyze SunScreen log files and produce detailed reports on topics such as bandwidth usage, protocol distribution, email and Web activity, FTP transfers, and Telnet sessions.

WFS is a third-party product from WebTrends that provides a greater variety of visual log analysis tools. If it is already loaded on your system, ensure you are using Version 3.0 or later. For further details, see the WebTrends Web site. See also the ssadm-welfmt(1m)man page.

The following procedure, performed on a system with WFS installed, describes how to use the SunScreen welfmt utility to enable WFS to analyze your SunScreen log files. It also describes how to produce the WELF log file from a SunScreen binary log file.

The welfmt utility is included on the SunScreen 3.2 CD-ROM.

1. Use the SunScreen configuration editor to retrieve the SunScreen log file from your Screen and save it:

   # ssadm log get > binary-logfile

2. Run the welfmt utility with the output of step 1 as input and save the ASCII output:

   # ssadm welfmt -f your-Screen-name -i binary-logfile > output-file

3. Import the welfmt output file to the system with the WFS product installed.
