jmap

Java memory map tool. More information: https://docs.oracle.com/javase/7/docs/technotes/tools/share/jmap.html.

  • Print shared object mappings for a Java process (output like pmap):

jmap {{java_pid}}

  • Print heap summary information:

jmap -heap {{filename.jar}} {{java_pid}}

  • Print histogram of heap usage by type:

jmap -histo {{java_pid}}

  • Dump contents of the heap into a binary file for analysis with jhat:

jmap -dump:format=b,file={{path/to/file}} {{java_pid}}
