Machine
How hard your PC is working, and every Claude Code session running on it.
Windows only for now
On a Mac the page says machine health isn't available yet.

Claude sessions
Every running Claude Code session, where it runs (ratchet, Windows Terminal, VS Code and others), its memory and CPU. Close ends a session. You can pick it up again later with resume.
When ratchet starts, it ends Claude processes left behind by agents it started whose window has gone. There's nothing to press.
If your PC restarted unexpectedly, a banner says when, with Show on chart.
