# fwloki

fwloki is a simple daemon to watch a log file (typically /var/log/messages)
for iptables logs, parse them and write them back out to [loki][] in a few
short microseconds. Optionally, you can also add some GeoIP metadata to the
logs at the expense of a bit more extra processing time.

Once in loki, you're free to do what you like with the logs, stick them in a
table in Grafana? Sure. Show the data in a world map to see who's targeting
your network? Of course. Inspect and drop traffic from repeat offenders? If
that's what you're into.

The world's your clam, really.
