Autoanalysys Warnings

Hi There
I was testing a new gimbal today and I just bothered to do an autoanalysys of the log. of my OCTO

I am still trying to learn to read the logs, may someone please have a look at the log

I am worried about the VCC WARN as I never had it before. I noticed that while in stabilize and AltHold the power to the Pixhawk is pretty herratic and as soon as I switched to PosHold it becames even. Is this normal?

The compass WARN doesn’t seem to be a big issue, even if it is weird as I was just flewing it at home, as I usually do and never had it before, could it be the new gimbal creating some interference? I ll give a try to redo the compass calibration.

Last and not least if someone could shed some light on the Baro Temp log as it s not clear to me what it records as the increase of degrees is too huge to be real.

Thanks for the help
