piSysStatus
Open Source
Quick Description
piSysStatus is a lightweight system monitor for the Raspberry Pi, designed for the small I2C OLED displays found on rack mounts like the UCTRONICS Pi rack. It renders the Pi's vital stats, including hostname, IP address, CPU temperature, and CPU, memory, and disk usage, directly on that tiny screen.
When you've got a Pi (or a whole stack of them) tucked away headless, an at a glance display saves you from SSHing in just to check whether a node is healthy or to find its IP. piSysStatus keeps that information visible on the hardware itself, refreshing continuously so the rack reports its own status.
