We've been using nagios and munin for years, this stack is rock solid. We added recently ELK. This feels overkill, heavyweight and fragile.

This is for a homelab. I think overkill is the point.

You can configure some nagios addons for performance metrics collecting, but is better to have a single/efficient/granular enough metrics collector. And time series monitoring helps a bit being proactive on bad trends or to give good context for past events.
