Resource metrics widget?

Hi,

Docker blew up my disk space today, so I'm in the market for a widget that shows percentages for the core DevOps metrics:

• CPU usage
• RAM usage
• Disk usage

Looking for a widget with solid macOS integration. That means, none of this menulet crap. It should actually appear under Clock -> Edit Widgets.

We have umpteen million unactionable Dow Jones widgets but evidently not a single system health widget.
