bcmstat

Simple Raspberry Pi command line monitoring tool:

• CPU fequencies (ARM, Core, H264, V3D, ISP)
• Temperature (current and peak) for Core and/or PMIC
• IRQ/s
• Network Rx/Tx
• System utilisation (percentage user, nice, idle etc.)
• CPU load (including individual cores when available)
• GPU mem usage
• RAM usage (with/without swap)
• Memory leak detection (D/A options - instantaneous and accumulated memory deltas)
• Undervoltage, ARM frequency cap and temperature throttle event monitoring
• Customisable columns

Tested with Raspbian, LibreELEC and OSMC/Raspbmc.

Displayed values can be coloured (white, green, amber and red) to highlight excess usage or resource depletion. Disable with m option.

View available options with -h.

Specify a default configuration in ~/.bcmstat.conf, eg:

xgd10

Installing on the Pi:

To install the latest version directly from this github repository:
