nTop is a traffic monitor - not a device monitor. It does a great job of looking at traffic flows between hosts, but no, you can't get interface utilization from a specific interface from a specific device.
If your devices don't support SNMP and / or port mirroring there's not much you can do. Depending on your exact environment and what you're trying to accomplish, nTop or anything won't be much good either. A probe/monitor needs to see the traffic somehow - sniffing, netflow, RMON tables via SNMP, etc. MRTG will get interface stats and runs on *nix (Perl) and web GUI, but again, your devices must support SNMP.

Hrm... Ntop actually looks closer to what i need than the rest. I have some limitations (not all hardware supports anything other than "just working") that force me to be 100% passive, which is why i liked ntop. Also, i am running under linux (prtg is windows). Is it impossible to configure ntop to look at interfaces for statistics rather than hosts?

I would use PRTG and setup SNMP on the switches. You can monitor the bandwidth on each interface of the switch regardless of the MAC address. http://www.paessler.com/prtg From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Noam Dev Sent: Thursday, July 26, 2007 1:56 PM To: [email protected] Subject: Re: [Ntop] MAC Address based summaries? The counters that I'm looking to see are mainly to monitor switches and the like. I'm dealing with some hardware that modifies MAC addresses (and set their own) but keep the original IP addresses. So, in order to see how much bandwidth each section sends/receives, i need to only look at MACs... (This is a question that i want to answer : how much bandwidth goes thorugh each link) On 7/26/07, Gary Gatten <[EMAIL PROTECTED]> wrote: Describe "monitor"? Unless you're in a really old or unique environment, TCP/IP is your layer 3 / 4 protocol so it's highly relevant. Give me an example of what data you want or what problem you're trying to resolve and I'll see if I can help.

Hello I would like to deploy ntop in a certain environment in which i want to monitor mainly switches and hubs. This means that for my purposes, IP addresses are of no importance, while mac addresses are the one i want to monitor. I have not been able to configure ntop to ignore IP traffic when summarizing hosts, and to use just physical addresses. Is it possible to configure ntop to do this or am i looking at the wrong solution for my needs? If the latter, any ideas for a more appropriate solution?
