Bandwidth monitor for entire network?

[Skelly]

I'm wondering if there exists a program that will show the bandwidth being used by all devices on my network in real time.

Try looking through the router configuration screen, there will be an area or tab called something like "connection status" or "network information".

Not the case. I'm using a Cisco M10 btw

If you can pull the data off your router using SNMP that's one relatively easy way of doing what you want. You can do all sorts of stuff once you have the data, I just graph it on the Linux box using RRDTOOL with 5 minute averages.

SNMP could be used for your "realtime" report too, example output of a simple script I just wrote up that queries my router once per second. Of course you could do something more interesting with the data like draw a fancy graph or render some kind of speed meter. In this case it just uses the snmpget command, and does a few calculations each second. All this of course requires a bit of programming and SNMP on your router

Thanks, Zatie, this looks like the solution. From what I've found, I'll have to install custom firmware such as DD-WRT or Tomato in order to get SNMP. The only problem I'm finding is that most of the data aggregators are linux only, and I'd like to run it on my main Windows machine.

Run it in a VM?
