What do you use to #monitor your #selfhosted server(s)?

I'm looking for something that can give me #metrics (historical graphs of cpu usage, etc.) and #alerting (email or matrix message when certain conditions are met). It's supposed to ease the load for me so preferably something simple over something complex.

Many thanks for your boosts.

Thanks everyone for your suggestions. I actually already use #monit and I like the simplicity but it only takes care of the alerting side of things.

#munit seems to be perfect for filling the metrics gap without bringing in the complexity of #grafana and co so I'll give that a shot and see how it goes.

Thanks again for the quick and helpful responses.
