prometheus-vcgencmd

prometheus raspberry pi vcgencmd

prometheus-vcgencmd exports the vcgencmd command in prometheus format. vcgencmd is a command line utility that can get various pieces of information from the VideoCore GPU on a Raspberry pi device. Use prometheus-vcgencmd and prometheus node_exporter to pickup your raspberry pi vcgencmd readings. You will have to install the vcgencmd command on your raspberry pi device (libraspberrypi-bin).

set as a crontab for prometheus node_exorter to pickup

*/5 * * * * /usr/local/bin/prometheus-vcgencmd >/var/lib/prometheus/node-exporter/vcgencmd.prom

you can download the prometheus node_exporter from prometheus.io or install via package "apt-get install prometheus-node-exporter" Prometheus node_exporter can pickup properly formatted prometheus files ending with a ".prom" file extension. Any file that resides in the '--collector.textfile.directory=' with a .prom file extension is parsed automatically. node_exporter Textfile Collector.

run as a python module

python3 -m prometheus_vcgencmd

run in python shell

$ python3
>>> import prometheus_vcgencmd
>>> prometheus_vcgencmd.Prometheus_Vcgencmd().stdout()
