[comp.os.vms] Measuring the load on Ethernet

XBR1Y028@DDATHD21.BITNET.UUCP (04/15/87)

Recently we have entered the 'new world' of Ethernet by installing an
fiber optics cable with 2 VAX 11/780's, a VAX 8500 and 6 Terminal-servers
on it.
Now we like to know, are there any tools (software within VMS or layered
products) available that allow you to monitor the load (congestion) on
the ethernet. I know that there are hardware monitors available to do that
- but don't have any of those.
Any suggestions, hints or tips are welcome !

In this months PAGESWAPPER  Lee K. Gleason documented a patch to the
Monitor Utility that  allow some here to hiden classes of Monitor to
work. One of the classes will allow the monitoring of Ethernet from VMS.

Warning: Since it is undocumented DEC will not support this "feature" of
VMS.

Good Luck.

The Patch for Monitor to show Ethernet Statistics is, according to the
article in Pageswapper(April 1987, Vol.8 #9, page VAX-14) for VMS 4.4,
But I have applied it to a VMS 4.5 system and it worked just fine.  

Anyother Version of VMS and you are on your own.
