PfGraph is a tool to integrate PF monitoring metrics into Graphite.
PFgraph retrieve metrics from an IOCTL on /dev/pf (the equivalent of
pfctl -vv -s info) and send them to the server, well formated with the
pickle protocol.
To run it once, just launch pfgraph.py <server> [port].
You should consider creating a cron to run it every minutes.
