CPU, memory, battery, network, disk, GPU, temperature and fans in your menu bar. You pick which ones show, and a click opens the detail behind it. Compact Health folds the whole machine into one item that stays quiet until something's off. MIT, macOS 15+.
Stats proved an open source monitor can be excellent, and iStat Menus set the
depth people expect. I wanted something between the two: free and open, with
alerting I'd actually trust.
The part I use most is Compact Health. It's one menu bar item that summarizes
the whole machine and stays quiet until something needs attention, so I'm not
reading six numbers all day. Alert rules fire on sustained thresholds rather
than momentary spikes, and there's a test delivery so you know what a 3am
notification will look like before it happens.
Everything is read from local system interfaces. No analytics, no crash
reporting; the only network call the app can make is an update check you
trigger yourself.

Love that Compact Health folds the whole machine into one item that stays quiet until something is actually wrong, that is the opposite of how these apps usually behave. Free and MIT licensed is a generous move too. Does the compact item still show enough at a glance on a notched MacBook where menu bar space is tight?
congrats on the launch. I run a Mac mini headless most of the day for local model work, so it's basically always on and I'm sensitive to anything that adds its own background load. for a tool that's polling CPU, memory, GPU, temp and fans continuously, what's mectrics' own footprint look like - is the sampling itself negligible, or is there a tradeoff between poll frequency and how much it costs you to run the monitor in the first place?
congrats on the launch! I've been using iStat Menus for years. Since I already have a license of iStat what would be the main drivers to bring me over to mectrics? I do like the Compact Health and the suggested CLI/JSON export sounds like a great tool for headless setups.
Love that Compact Health folds everything into one quiet menu bar item that only speaks up when something is actually wrong, which is exactly how a monitoring tool should respect your attention.
the GPU and temperature tracking is what caught my eye - I've had my mac silently throttle during long batch jobs before and only noticed afterward from how long everything took. would compact health actually flag sustained thermal throttling, or just raw temperature being high? those aren't quite the same thing and the throttling itself is usually the real problem, not the number on the sensor.
The Compact Health mode is a really thoughtful touch, surfacing issues only when something actually needs attention instead of cluttering the menu bar with constant noise.
Compact Health is the bit I'd use. I've got a Mac Mini sitting headless running agent jobs, so the menu bar is exactly where I never look. Is there a way to get the same alert rules out over CLI or JSON so I could pipe them somewhere else, or is it menu bar only for now?
Compact Health staying quiet until something's actually off is the detail that matters. Every other menu bar monitor I've used just dumps every number on you all the time and you tune it out.
