ACPI Error: AE_NOT_EXIST, Evaluating _PMM (20190816/power_meter-325)

The same problem on an HP server and there is a smarter solution found here: https://www.novell.com/support/kb/doc.php?id=7010449

Instead of disabling sensors in netdata altogether, you can just disable the acpi_power_meter kernel module, which doesn't work anyway on affected HP servers due to a BIOS bug. This way netdata can still get the temperature readings.

This is how you can disable the module immediately:

sudo modprobe -r acpi_power_meter

And this is how you make it permanent:
