Hi all,

I have a question related to calculating the percentage ring utilization in
the /usr/OV/conf/mibexpr.conf file.

To calculate the abovementioned value for a Token ring hub with RMON
support, I make use of the mib value: .1.3.6.1.2.1.16.1.3.1.4, which is
translated:
mgmt.mib-2.rmon.statistics.tokenRingPstatsTable.tokenRingPstatsentry.tokenR
ingPstatsDataOctets
This value is then multiplied by 100, an the result divided by
.1.3.6.1.2.1.2.2.1.5 (IfSpeed).
The result should then be the percentage ring utilization.

Question number one:      Is this the best and most accurate method of
calculating Ring utilization?
Question number two:     If I browse the mib, the tokenRingPstatsDataOctets
value keeps rising. In other words, it is not a Delta Value.
               Does anybody know how these values get converted to give a
delta value each time the graph is updated?

Thanks
