Any freebsd/PfSense realtime bandwidth monitoring tool?

Question

i need to know if there is any Tool (specifically for FreeBSD) , through which i can get the Realtime network traffic usage of any Host/IP , and which should also run on Multiple interfaces as well? i have tried ntop, but its of no use. tried iftop, but it does not supports merging of multiple interfaces. any other tool to accomplish this task?

Regards,

Solution 1

Maybe systat -ifstat 1 will work for you.

Solution 2

When you say ntop is no use -is that because you had problems using ntop, or that it didn't give you sufficient info?

You could install the pfflowd package which is a netflow emitter - I only played around with it a little and found some netflow collectors didn't seem to like it as it didn't totally conform to standards.

This thread http://forum.pfsense.org/index.php?topic=11185.0 mentions people being happy with Manage Engine's Netflow Analyzer Pro although the thread also mentions the free version only supports one interface. (and you need to run this on a box external to your pfsense)

Also if you are at the console or can ssh in, pftop gives real time info, and according to this thread http://forum.pfsense.org/index.php/topic,11289.0.html the bandwidthd package can also give per ip info.

This will only give the aggregate bandwidth used by each network device (interface) - it doesn't give a host breakdown.

If you really need per-IP/per-subnet breakdowns a netflow emitter is really what you need. (You don't need the pfflowd package, though it's pretty friendly compared to the alternative, ng_netflow from the built-in netgraph tools. You will need a netflow collector like flow-tools and a netflow "cruncher" like jkflow to analyze the data...)

Is it possible to to make systat show data as CSV (comma separated values) for scripting, Jrm?

Not that I'm aware of. I don't see anything in systat(1).
