Currently Orion's Network Availability chart when added to the summary page depicts ALL nodes network availability. It would be GREAT if it could be modified to be by modified so that you can monitor a group of devices or vendors, etc so that you get a clear picture of availability.
For instance, if I wanted to have the Network Availability chart on the summary page depict just infrastructure devices it would do this. Likewise if I wanted to see how the servers are doing it could do this as well.
I know you can limit a view based upon selected devices but if you have a view that needs to see the status of all devices for all things except for the Network Availability chart.
