Hello. Is there any way to log nozzle&bed heaters' outputs in voltages or anything else ? I want to track how my heaters behave over time. RepetierHost shows those values visually. Thanks in advance for helping. An example is below

There's an M573 gcode command but Marlin doesn't support it.
There's probably some way of adding an Arduino, creating a voltage-divider circuit and just measuring the pair of wires to a hotend and then sending the data over serial back to the Raspberry. I can't imagine this being of much help to someone unless they're manufacturing hotends or similar.
Is there a reason to monitor the voltage ?
The Temperature is available in octoprint.
you can use 2x INA219 to messure the voltage with the pi
