Figure 33 Java Collection Leak Locations Visualizer
After some time, the alert icon may disappear if:
• HPjmeter determines that the previously reported leak object is not a leak.
• The leak-related collection object is removed by garbage collection.
HPjmeter removes the alert icon when it removes all the leak nodes and no new memory leak is
detected.
NOTE: This alert is not available when dynamically attaching to a running Java application.

Array Leak Locations Alert
HPjmeter detects potential array memory leaks and identifies the source-file line of the leak. By
default, this alert is activated when the leak is 10 MB/hour or more.
The console main window displays an Array Leak Locations Alert when an array memory leak is
detected.
Double-clicking on the alert displays the Array Leak Locations visualizer, which shows:
• Each detected array leak type
• The leak source location
• The leak duration
• The current size of the detected array
Mousing over an array leak alert pops up a yellow description box with explanatory text.
