The light grey is the amount of memory reserved by the JVM. It is only
visible if you do not specify Xms, so many people do not have that.

Generally the dark grey (the amount of heap that is actively used to
hold data) will fluctuate a lot and I don't find it very usable for
observing and tweaking heap size. The GC-log is better.

Thanks Erik

I see three colors in the JVM usage bar. Dark Gray, light Gray, white.
(left to right).  Only one dark and one light color made sense to me (as i
could interpret them as used vs available memory), but there is light gray
between dark gray and white parts.


Thanks

Nawab:

Images are stripped aggressively by the Apache mail servers, your
attachment didn't come through. You'll have to put it somewhere and
provide a link.

Generally the lighter color in each bar is the available resource and the
darker shade is used.

Best,
Erick
