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.
