All,
I'm looking for an at-a-glance way to show Top-N WAN circuit utilization that shows how long over the previous day the interface was above a certain utilization threshold. Any guidance would be appreciated. Thanks.
You could try creating a Custom Multiple Object Chart(See attached image). You would list all of your WAN interfaces and there is an option "Number of top series displayed" where you would put the number for top xx and select time period "Yesterday". This will list all of your top xx WAN interfaces on a chart and will graph their percent utilization. I would choose sample interval to every minute as granular as possible. This doesn't take into account the utilization threshold part of your question, but may be a good start.
