I came across the MenuMeters App in the fall of 2021. I installed it on my Mac (2018 Mac Mini, macOS Big Sur 11.6) in mid-November. I have been running it ever since. One of the things I like about MenuMeters is that it is Free Open Source Software (FOSS).

The Preference Panels for MenuMeters offers several configuration options to customize the App.
As with many modern programs, MenuMeters will automatically check for updates. MenuMeters is a port of the App developed by Alex Harper at http://ragingmenace.com.
