Memory pool size data #285

Open ghost opened 1 year ago

ghost commented 1 year ago

It is unclear that the parsers are collecting the right data needed to support calculations such as Memory Pool Size % based on the number of regions allocated to Eden, to, archive, reserved and old space.

I think the parser collects the right data, but then there is a calculation to turn the number of regions into a number of bytes based on region size. The trouble is that the value for regionSize might be zero. It might be better to just set the number of regions.

I think there is a data structure to collect the region information. I'll drop more testing in here today if that is ok with you David.
