Chef Automate Dashboard - Information gathering

Hello forum,

I am quite puzzled at the moment by the Chef Automate Dashboard.
It shows uploaded Cookbooks with version info, Databag items created/deleted etc.
However our Automate is NOT yet connected to any Chef Infra Servers. At the moment it is solely used to display audit compliance runs.

I am wondering, where does Automate get its information for the dashboard from? Checked the config and cannot find anything relevant to that question.
Can someone point me into the right direction?

Thanks!

edit: To clarify, I mean the "Event Feed" Dashboard.
