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.

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.
