Troubleshooting • Logging voltage from vcgencmd to influxdb via telegraf

Code:

 $ cat /usr/local/bin/influx-vcgencmd.sh#!/bin/shv=$( vcgencmd measure_volts | tr -c -d /[[:digit:].]/ )echo "cpu voltage=$v"

Code:

$ tail /etc/telegraf/telegraf.conf[[inputs.exec]]  commands = ["/usr/local/bin/influx-vcgencmd.sh"]  timeout = "3s"  interval = "3m"  data_format = "influx"  [inputs.exec.tags]    bucket = "system"

Code:

$ influx-vcgencmd.shcpu voltage=0.8403$ sudo -u telegraf influx-vcgencmd.shcpu voltage=////1000
