Hi,
	Has anyone out there recently evaluated simple commercial ethernet
monitors?  We are looking for an inexpensive PC based package that will run 
with a 3c503 Ethernet card.  
The package must have:
	Traffic -	Utilization, Peak, Collision count
	Ability to store data and retrieve for later analysis
	MSDOS, EGA graphics capability
	Real time display

We would like :
	C program interface for additional analysis programs that are written
		in house
	Ability to store data in spreadsheet format
	Audible alarm when utilization is exceeded
	Count how many "users" access a given ethernet, if not IP, address
	Display count of recieved packets by protocol

For those who are interested, we need this as a temporary monitor of a
hub for our campus wide network.  We have to use a baseband cable to
"bridge" together two 5MB broadband systems.  This cable is a central
point of failure and we need to monitor it continously.  We will be
getting a more sophisticated network monitoring system in the future,
but we need the monitoring now.
Thanks
Larry
