Good luck. So are we all. Including the main development team.
We have agreed on level-0 and level-1 being critical and important (with
some personal opinions making flexibility around what is considered
critical and important), and on level-9 being for raw data dumps of
things which might be exceedingly huge like I/O buffers.

Between 2 and 8 the levels are the collation of arbitrary choces of
hundreds of developers across decades of work. Even the sections are a
bit ad-hoc in their numbering.

To get anything useful out of the 2+ debug levels you have to figure out
what detail you want visible, browse the code and find out what debug
section and level it is logged at (or patch some debugs in if they are
missing) then log that and wade through the extra bits thrown out at you.
