icinga2-plugin-raspberrypi_voltage

Measuring voltage values and check whether

• host is currently throttled or not and
• host was previously throttled or not

It is tested on Raspberry Pi Models: 1, 2 & 3, and I didn't encounter any problems so far. It is experimental, so use it at your own risk and don't stop thinking when using ;) Drop me a note when you run into problems. Status worksforme :)

It was not that easy to get information about the hexcodes and their meaning; essentially, my only resource was this forum posting. Actual states are only shown when they currently happen, previously states remain until system reboot - that's why I don't treat previously happened events as CRITICAL. The command vcgencmd get_throttled 0x7 should reset the previously states, but in fact, it doesn't work for me. When you have further information on this - please let me know!

Usage

$ ./check_raspberrypi_voltage

Example

$ ./check_raspberrypi_voltage
ALERT - The following events happened on your host:
Previous limited ARM frequency to reduce core voltage
=> You can assume >80'C system temperature as the reason.
=> Code 0x20000
|core_voltage=1.2000;;;; sdram_c_voltage=1.2000;;;; sdram_i_voltage=1.2000;;;; sdram_p_voltage=1.2250;;;; arm_clock=600000000;;;; core_clock=250000000;;;; h264_clock=250000000;;;; isp_clock=250000000;;;; v3d_clock=249999000;;;;
