BLUF: Is there a "datadog-for-home"?

I've a ton of stuff running at home ranging from a 5-node PI cluster with various containers running on them including things like self-written python scripts doing "super important" stuff, node-red running everything about my energy setup, pfsense, TrueNAS etc.

Logging is painful and I've just lost about 4 hours trying to find a fault which stopped car charging. Lots of rabbit holes were entered as I currently don't have an end-to-end logging solution.

​

What does everyone else use?
