Thread dump

You can dump the thread information for all live threads with stack trace by accessing "/jvm/threaddump". If MediaType.JSON is specified in HttpHeaderNames.ACCEPT, the thread information will be converted to a JSON. Otherwise, the thread dump will be converted to a plain text. 

 // Exports thread information as a JSON array
 curl -L -H "Accept: application/json" http://my-service.com/internal/management/jvm/threaddump
 // Exports thread information as a plain text
 curl -L -H "Accept: text/plain" http://my-service.com/internal/management/jvm/threaddump

Heap dump

You can also dump the heap in the same format as the hprof heap dump by accessing "/jvm/heapdump". 

 curl -L http://my-service.com/internal/management/jvm/heapdump -o heapdump.hprof
 // Dump only live objects that are reachable from others
 curl -L http://my-service.com/internal/management/jvm/heapdump?live=true -o heapdump.hprof
