As well as the Sniffer and the LANalyser another network monitor to consider
is the SpiderMonitor. This differs from the other monitors on the market
because it uses an intelligent network board with its own processor
rather than a dumb board. The board has its own multitasking executive which
allows it to gather station statistics at the same time as monitoring network
load. The load can be displayed graphically over a specified time period.
The monitor can also capture and decode packets and traffic generate while
this network monitoring is going on.

Having an intelligent board means that the statistics are gathered
continuously even when the PC which the board is plugged into is running
another DOS program. Multitasking also means that the monitor is not dedicated
to measuring things like the network load in exclusion to capturing data
about other aspects of the network. It is far more useful to be able to look
at network load and a table of station traffic than just network load.

The machine has been designed to be good at collecting statistical information
about the network as well as capturing and decoding packets. Decoding seems
to be the area which other network monitor manufacturers like Data General
have concentrated on.

They tend to be weaker on collecting tables of statistics about traffic sent by
machines on the LAN.

Hope you find this useful

Your statement that the SpiderMonitor uses an intelligent board w.
microprocessor whereas "the others" (LANalyzer and Sniffer) use
"dumb boards" is totally false. All three products use boards that
have something at least as powerful as an 80186, 10 Mhz, and 512KB of
RAM. The top-of-the-line LANalyzer has even more horsepower on-board.

Please try and be more careful about making statements about the products
of competitors in a public forum. Here you will get caught. Unfortunately
spreading wrong competitive information directly rarely is! Welcome to
the U.S.A. Spider!

Thanks for correcting me.

It is true that the LANalyser uses an 80186 or 286 on board. As for the
Sniffer I have no indication on the spec sheets I have which processor
it uses. It was my mistake classifying these boards as dumb.

The message I was trying to get over was the benefits of multitasking on the
board rather than any comparison of hardware. I apologise for any confusion
caused.
