Thanks, this is a good reference point. > It might not be a sufficient box for monitoring 2000+ machines, but for > what I've got it works very well. The segment I'm monitoring is not We have a [EMAIL PROTECTED] GHz, 2GiB RAM... I know that our RAM is not sufficient to monitor 2000 hosts (we are working on it ;) ). However I have to say that NTop frequently crashes within minutes since its start, with a lot of RAM still available. Sometimes it manages to survive for several hours, swapping a lot... > isolated, but the ntop box is sharing a hub with the firewall, so I'm > seeing not just the Internet traffic but also the broadcast traffic for the > segment as well. I haven't tuned the OS either. It Just Runs. We set up our router to mirror the "interesting" traffic on a dedicated port which is directy connected to our NTop box. We can adjust the packet rate coming out from our router (i.e. sample 1 packet every 10 or 100 and so on). We noticed that limiting the traffic this way does not help stability. > Oh, yes - I did install ntop from ports (3.0_1).

We are testing NTop 3.0/FreeBSD 5.3 on another machine (the hardware is similar to yours) to see if we get a different behaviour. I'll make you know...
