Erm, what is it that you want?
You want to report on the uptime of your WAN link as in the percentage of time the interface was up?
If thats what you want you can see graphs in Orion or just use a report but I am assuming you are talking about something different?
Please elaborate a bit on what exactly you want to achieve.
I want to be able to run a report and see for example for the month of March, the WAN circuit was up 95% of the time.
I'm not looking for a graph, I'm looking for a percent uptime metric.
