Is there a way to create a view that has a graph of the CPU of all devices within the network? In the past I've used custom HTML to pull just the graph that I needed, but I can't seem to find that now.
I am not 100% sure your use case here, but the charts are limited to 10 values per chart, which is still way to much to be usable
Look at the Perfstack feature, which will allow you to create a PerfStack project with all the CPU charts you wish to display, which you can then embed on a page. Alliteratively, you can use the standard charts or tables ensuring you create suitable filters to control what data is displayed in each.
