I am runing FreeBSD 8 stable with PF as firewall, I am looking for any tool for parsing PF log's.

Does this help (from the first listing in google search for PF logs).

The log file written by pflogd is in binary format and cannot be read using a text editor. Tcpdump must be used to view the log.

To view the log file:

# tcpdump -n -e -ttt -r /var/log/pflog

other useful info here

I hope this helps.

I am looking for some thing built with perl or C, some thing give statics, show time, and highlight issues(for scanning for example), with structured format like tables. – SIFE May 29 '11 at 15:36

How about Splunk? It processes any machine data and gives ability to do all sorts of acrobatics with it.
