Hi Mattew.
You have to use this formula if your interface is half duplex:
(ifInOctets + ifOutOctet)/(ifSpeed)*8*100. ifSpeed is bit whereas ifInoctet is
in octet, this is why you have to multiply by 8. This formula give you a result
as a percent.
If your interface is full duplex, you will have to monitor both in percent and
out percent, is it to say:
ifInOctets / ifSpeed *8 *100 and
ifOutOctet / ifSpeed *8 *100
and to set a threshold on both (for a value of 75).
I hope this would be helpfull.

Hello all!
I have a question. When setting up a monitor in Netview, my customer
wants to know when network utilization reaches 75%.
Let me know if I am correct. I was going to set it up to alert me when
the IfInOctet/IfOutOctet count reaches 7500000 for a 10Mb interface or
75000000 for a 100Mb interface. Even though I have the % button
selected, it still seems to need the actual count. Ami I just off my
rocker or is that actually the case? Is there a formula I should be
using instead?
Thanks in advance!
Matthew Clayton
