How to view memory allocation stacktrace in Java VisualVM
提问by sina72
This article describes how to view memory allocation stacktrace in Java VisualVM: http://rejeev.blogspot.de/2009/04/analyzing-memory-leak-in-java.html
本文介绍如何在Java VisualVM中查看内存分配堆栈跟踪：http: //rejeev.blogspot.de/2009/04/analyzing-memory-leak-in-java.html
In short, define a custom preset in the Java VisualVM options and check the "record allocations stack traces" checkboxin the memory settings tab.
简而言之，在 Java VisualVM 选项中定义自定义预设并选中内存设置选项卡中的“记录分配堆栈跟踪”复选框。
Now, when I select that custom preset and start memory profiling, I still cannot view the memory allocation stacktrace. There is no right-click-on-item action "Take snapshot and show allocation stack traces"as described in the article, nor a anything like that. I am using VisualVM 1.7.
现在，当我选择该自定义预设并启动内存分析时，我仍然无法查看内存分配堆栈跟踪。没有文章中描述的右键单击项目操作“拍摄快照并显示分配堆栈跟踪”，也没有类似的操作。我正在使用 VisualVM 1.7。

Enable Memoryprofiling in Samplertab, then press a Heap Dumpbutton.
在Sampler选项卡中启用内存分析，然后按下Heap Dump按钮。

If you can't see this option, go to Profiler -> activate "Settings" check box and activate "Record allocation stack traces" while the profiler is not active.
如果您看不到此选项，请转到 Profiler -> 激活“设置”复选框，并在 Profiler 未激活时激活“记录分配堆栈跟踪”。
