[net.lan] Ethernet monitoring

menges@unc.UUCP (John Menges) (07/09/85)

I'm wanting to gather some statistics on the utilization of our
ethernets, and would like to know if anyone out there is aware of a
reasonable way of doing this.  I'm thinking of something like a box
that will sit on the ethernet and gather statistics on network traffic,
reporting its accumulated statistics on request via a serial line.
I'm aware that this information is available on a per-host basis
via netstat, but would like to find a method that's a bit less unwieldy.
Please respond directly to menges@unc, and I will post a summary.

Where can we order a copy of the MIT package to monitor the Ethernet?
Or, better yet, does someone have one that will run on a Sun, microVax,
or real Vax?

       Excelan has a nice box that does this, the Excelan Nutcracker,
but it is overpriced at $49K.  The MIT software for the IBM PC has some nice
logging and statistics facilities, and at $12 for the object and $75 for
the source, plus $650 to 3COM for the Ethernet controller, it's a bargain.

Spider Systems produce an Ethernet monitor which sells for 4618 pounds.
It knows about the format of IP, XNS and ISO packets and can be used
to trace packets that match a particular pattern. A nice feature is the
ability to use local host names instead of Ethernet addresses. It can
also collect statistics, draw usage graphs, generate traffic, and test
the connectivity of the network.

We saw a demonstration the other day and liked it a lot, not least
because it tracked down a long-standing mysterious bug very quickly!
In fact we liked it so much we're going to buy one.

As a relatively new product, it is only available in the UK at present.
