Simple Raspberry Pi command line monitoring tool:
- CPU fequencies (ARM, Core, h264)
- Temperature (current and peak)
- 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/Aoptions - instantaneous and accumulated memory deltas)
Tested with Raspbian, OpenELEC and 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:
curl -Ls https://raw.githubusercontent.com/MilhouseVH/bcmstat/master/bcmstat.sh -o ~/bcmstat.sh
chmod +x ~/bcmstat.sh
