| - | * '''jmap''' - This command will then dump a summary of the current memory map to the console. While not as sophisticated as the later versions of java, it still provides some rudimentary functionality. This command will then dump the memory map of the target process-id# to an hprof file within the current directory (or specified directory if you expand on 'filename'). | ||
| - | * '''jstack''' - This command will then take a thread dump of the java process specified and dump it to the console. It will only provide both Java & C/C++ threads during the trace. You may want to consider redirecting this output to a file with the ''>'' modifier. This command will then take a thread dump of the java process specified and dump it to the console. You may want to consider redirecting this output to a file with the ''>'' modifier. | ||
