I think the info provided by MenuMeters (It's "Confirmed to run OK on El Capitan 10.11, Sierra 10.12, High Sierra 10.13 and Mojave 10.14.") in real time, although not quite as extensive, may be more helpful than the historical info provided by your "Analytics" EtreCheck pane, and that that provided by your "Storage" pane can be had in considerably greater detail from (your) DaisyDisk and (my) GrandPerspective.

It seems to me that, like TechTool Pro, Disk Warrior, and others of their ilk, EtreCheck is fighting to maintain an appearance of relevance in the face of disappearing need.

All of which is NOT to say that other of EC's output isn't unique and useful.
