It would be great if you could have gauges on maps.
Clicking on a an interface object it should give you a drop down menu. (Options are good) Ideally you would have some of the following options:
1. View Interface Gauge (The gauge presented would give you the option to choose if you wanted it as% or bps etc)
On a side note you could offer the option to the user to automatically provide certain dynamic details under a comment entry.. such as speed uptime.. current %/bps utilization etc..
2. View Interface Details
3. View Device Details
