ISE: System Summary Dashboard - how to display multiple nodes at once

[Jemmotar]

Since 3.x upgrade I can see on the main home dashboard the widget "System Summary" displays only 1 node.
Is there any native way to display multiple nodes at once? Any report?
Is there any way how to get the data out for external tools like Grafana / Splunk? I was googling API for system statistic, but I was not able to find any. Any help and opionion is welcomed.
I would be interested whats behind Cisco's decision to allow the techs display only one node summary instead summary across the whole deployment as it was on older versions.

You might have a look at the System 360 feature enhancement in ISE 3.2 and the related ISE Webinars discussing these features.
