Do you mean /var/log/pflog ?  Which is the default location where a
record of logged packets ends up if you run pflogd(8).

That's actually a pcap (packet capture) file, and you can read it
using tcpdump:

  # tcpdump -r /var/log/pflog

Each packet is recorded with a high resolution timestamp that tcpdump
will display for you -- like this naughty chap suffering the consequences
of trying to brute-force my ssh daemon just before 1:00pm today:
