Default dump agents

The JVM adds a set of dump agents by default during its initialization. You can override this set of dump agents using -Xdump on the command line.

See Removing dump agents. for more information.

Use the -Xdump:what option on the command line to show the registered dump agents. The sample output shows the default dump agents that are in place:

java -Xgcpolicy:metronome -Xdump:what
