我是 Heaps 的新手,谁能建议我如何获取任何 Java 进程(如 Jmeter)的堆转储。我读过 jmap 命令,但我不知道在哪里以及如何执行/编写它(在 eclipse 或 cmd 中)。这可能是一个非常基本的问题,但仍然需要建议。我可以从任何地方下载 jmap.exe 和 jhat.exe 吗?谢谢

Here is the command:

这是命令:

<JDK_HOME>/jmap -F -dump:live,format=b,file=<file_name.hprof> <process_id>

You can mention the file location here in this command.

您可以在此命令中在此处提及文件位置。
