Yeah, diagnostics are quite a weak spot. Apple is nice and tidy when stuff just works™, but when it doesn't, it can be hell.

(See, for example, all the Continuity stuff. Great when Universal Clipboard just copies where you need it to, and your Watch just unlocks your Mac unasked. But when those randomly stop working? Good luck figuring it out. Typically involves clearing caches, logging out of iCloud and back in, praying to Cthulhu, and maybe a raindance or two.)
