Set a usage threshold

Where usage threshold can be set, a “0” (zero) appears in the Usage Threshold box. To set a

threshold, replace the current value with a desired, valid value in the box, and press Enter. To see

what values are valid for a region, mouse over the Usage Threshold box.

On pressing Enter, a red marker will appear on the region usage bar to mark the point at which

the threshold is reached. The bar color turns red when the threshold is reached and a notification

is generated.

Start verbose GC

At any point, you can click the verbose GC check box to start collection of verbose GC data by

the JVM. The JVM usually writes this information to stdout. Uncheck the box to stop logging

verbose GC data.

Perform a garbage collection

At any point, you can click the Perform GC button to force a System.gc garbage collection on

the heap.
