Because FreeBSD does not have an SNMP interface to the firewall statistics
(which is what I was quoting), I have written a very simple interface
to them which samples them at 15 minute intervals and stores them,
along with the time of day, into an accumulating file.
This isn't directly suitable for input to MRTG nor to Prometheus etc,
but possibly could be adapted to feed Cacti, as that package apparently
uses rrdtool as its basis. It would also be possible to feed these
directly to Gnuplot to generate simple time series graphs.
I can make the raw file available on the web server, or I can generate
some graphs (.png format) and make them available instead. Gnuplot also
says it can create a "mouseable" web format graph, whatever that is.
Which do people think they might find more interesting?
