Oh that sucks. Interface availability is more important than interface utilization (see Robb Webb's CAW presentation "8 Metrics That Matter"). What people don't understand is that you don't need to look at utilization unless it's impacting a user. 100% utilization is not bad! You're getting 100% of what you're paying for! That's great! Also interface utilization is a misnomer, since an interface transmits bit serially; which means that interfaces are never 64% utilized! They're either transmitting a bit or not. Interface utilization is a construct used to help us understand what percentage of a certain period that an interface was 100% utilized (transmitting a bit).
On my interface context, i need the following views on the first page (with the corresponding units):
Discards inbound (in packets per second)
Discards outbound (in bits per second)
Errors inbound (in bits per second)
Interface availability (in %)
CBQoS/CoS views
On the second page i need (all in % and in bps):
Interface utilization in/out
Stacked protocol trend in/out
Stacked tos in/out
top conversations
top hosts
On the third page i need:
interface details, group membership, polling rate, etc.
