Record statistics from a Raspberry Pi's VideoCore processor

pi-stats

pi-stats reads stats from a Raspberry Pi's VideoCore processor and writes them to stdout using InfluxDB's line protocol0.

Based on ericlagergren's pi-stats https://github.com/ericlagergren/pi-stats including pull request from hancockks for throttling information. In addition the stepping has been delayed from 1 second to 10 seconds by default to reduce unnecessary I/O to the Pi's SD card.

Installing

To have everything installed for you, run make all. You'll likely need root privileges.

To install pi-stats manually:

1. Build the pi-stats binary with make (or make install and skip step #2)
2. Copy pi-stats to /usr/local/bin
3. Copy pi-stats.service to /etc/systemd/service/ (or make install-service)
4. Copy pi-stats.conf to /etc/logrotate.d/pi-stats (or make install-logrot)

Once you've installed pi-stats, make sure to enable and run the service with systemctl enable pi-stats and systemctl start pi-stats, respectively. Again, you'll likely need root privileges.

Configuring

By default, pi-stats reads from VideoCore once per second. This can be configured with the -s flag, which is the number of seconds between reads.

Usage

The stats are written to /var/log/pi-stats.log, which can then be parsed by Telegraf1.
