Prometheus variables

There is a sample prometheus.yml configuration in the docs/ directory. See the Prometheus getting started docs for more information.

• gqgmc_geiger_cpm (histogram) CPM readings.
• gqgmc_geiger_cps (histogram) CPS readings.
• gqgmc_power_volts (histogram) Voltage readings.
• gqgmc_sys_errors (histogram) Error counts. Records problems communicating with the device.

Configuring udev

Copy the linux/51-gqgmc.rules file to the /etc/udev/rules.d directory and force the reload of udev rules:

sudo cp ./51-gqgmc.rules /etc/udev/rules.d/51-gqgmc.rules sudo
udevadm control --reload-rules

Disconnect the GQ GMC-300 from the computer and then reconnect. Verify that there exists a /dev/gqgmc in the /dev directory with read/write permission for all users.

ls -la /dev/gqgmc
