mectrics

Mac users who want to keep an eye on system health, including people running headless Macs, usually have to open Activity Monitor or wire up heavier monitoring tools. Mectrics puts the numbers you choose in the menu bar, with the rest one click away in a Dashboard popover, and raises an alert when a rule holds long enough to matter. For headless Macs, a read-only mectrics command returns an exit code that drops into cron or an existing monitoring check. Example: set a thermal pressure rule, and mectrics check exits non-zero when the limit is crossed.
