pflow needs software to collect data; you might want to look at nfsen/nfdump,
pmacct or flow-tools - all are in ports. (Note that pflow is compatible
with Netflow).

There are a few options available. One is to write the rule set with
labels to collect statistics, making sure the labels are one per IP
address.  The other main option is to use pflow(4), with 'set
state-defaults pflow' or 'keep state (pflow)' for individual rules in
your rule set, set up a collector somewhere and extract the data you
need per IP address.  If you go for pflow, the pflow man page will get
you started.  I'd recommend taking a look at Michael W. Lucas' recent
book for the Netflow analysis part, while the upcoming second edition
of the Book of PF contains a bit of material about both approaches too
(the first edition has only the labels part).

Bandwidth consume by IP address

2010-10-01 Thread Hermes Ojeda Ruiz
Hi,

I'm working with a OpenBSD firewall on embedded hardware, and the client
want to know the bandwidth consume by IP address.

I don't know if this is possible using PF, another tool or making scripts to
get the information.

I'm worried about the performance, because, some weeks ago I make a question
in the list "How distribute bandwidth by IP's", and I solved it, using a lot
of cbq's by ip address (~150 ip address) like was recommended on the
replies, of course, using an script to generate it. That's work, perfect,
but generate some delays on the packets, and if I log everything it can make
the connection useless. The firewall is running in a Soekris net5501.

Sorry, if this is a fool question, and my bad english.
