heap-dump-file 要查看的二进制Java堆转储文件(Java binary heap dump file)。 如果某个转储文件中包含了多份 heap dumps, 可在文件名之后加上#<number>的方式指定解析哪一个 dump, 如:myfile.hprof#3 示例 jmap转储可以使用如下方式: jmap -dump:file=DumpFileName.txt,format=b pid 例如: C:\Users\Admi...
Acquiring the heap dump is VM specific. Memory Analyzer comes with several so called heap dump providers - for Oracle and Sun based VMs (needs a Oracle or Sun JDK with jmap) and for IBM VMs (needs an IBM JDK or JRE). Also extension points are provided for adopters to plug-in their o...
live On IBM JVMs this forces a garbage collection before a dump is taken. This could affect the performance of the program running on the target JVM, but may reduce the size of PHD Heap dumps. On Oracle and OpenJDK JVMs this dumps only live objects into the HPROF file and should reduc...

Select the dump file and clickOpen. You can now inspect the heap snapshot at your leisure. Some snapshots may take a long time to load, on the order of minutes or even hours. Note that Chrome will refuse to load the file unless it has the.heapsnapshotextension. ...
To capture a JVM heap dump by using jcmd, run the following command in the debug console: app[/]$ jcmd1GC.heap_dump /tmp/dump.hprof Either way, you can then access the dump file at/proc/1/tmp/dump.hprof. Download the dump file to local ...
outputFile: the path of the file for the dump. This file should have the hprof extension. live: if set to true, it dumps only the active objects in memory, as we saw before with jmap. In the next sections, we’ll show two different ways to invoke this method in order to capture ...
