GoDawgs,

MicroFocus was consulted and the initial question of if there was documentation was answered quickly as no but then more questions were asked. Here are the questions and answers:
* Are the Used and Free numbers on the Memory Monitor a snapshot at the time the Debug Console web page is opened?

Yes, It is totally correct.

* Are the Initial and Maximum values when the system was first brought back online and the maximum configured memory available?

Yes, it is correct.

* Is the Committed number the maximum memory consumed from the time the system was started until the time the webpage was opened?

Not really, The Committed memory, is a measure of how much memory the JVM heap is really consuming in the guest.

the final question was then restated and answered as follows:
Can I assume the Committed memory is a also a snapshot value?
Yes, we can see it in that way, and it represents the amount of memory that is guaranteed to be available for use by the Java virtual machine.
