Lumen Monitor is a menu bar app and a set of desktop widgets for your Mac. It shows CPU, memory, and free space on each physical disk, plus the optional readings you turn on.
Menu bar
The menu bar item is the live glance. Choose which readings appear, and in which order, from Settings. Battery, network, swap, memory pressure, load, uptime, and per-core CPU stay hidden until you enable them.
Window and settings
Open Window shows every reading. Click a disk to reveal it in Finder. Settings (Command-Comma) has two tabs: Peaks, for the limits and the alert color, and Menu Bar, for the readings, the network interface, and the appearance of the menu bar item.
Widgets
Open Lumen Monitor once, then add widgets from the desktop widget gallery. Each reading is its own widget, and the history widgets are separate from the live ones. On a desktop Mac with no battery, the battery widgets say that no battery is installed.
History
Charts need two samples before they draw. The app records about one sample a minute while it is running. Until then a history widget says it is collecting history.
