The heapdump endpoint provides a heap dump from the application’s JVM.
Retrieving the Heap Dump
To retrieve the heap dump, make a GET request to /actuator/heapdump.
The response is binary data and can be large.
Its format depends upon the JVM on which the application is running.
When running on a HotSpot JVM the format is HPROF
and on OpenJ9 it is PHD.
Typically, you should save the response to disk for subsequent analysis.
When using curl, this can be achieved by using the -O option, as shown in the following example:
$ curl 'http://localhost:8080/actuator/heapdump' -OThe preceding example results in a file named heapdump being written to the current working directory.
