Hi Techies,
I have recenty been reading Cisco Press' new book called "Peformance and
Fault Management" and they stated to measure utilization on a WAN interface
(full-duplex); it is recommended to use the following formula:
max ( delta(ifInOctets), delta(ifOutOctets) x 8 x 100)
-
ugh for you, especially if the traffic is bursty. In a
situation like that you might want to sample every 5 or 10 seconds just
for fun to watch the ebb and flow of traffic on a link.
