System dumps

System dumps involve dumping the address space and as such are generally very large.

The bigger the footprint of an application the bigger its dump. A dump of a major server-based application might take up many gigabytes of file space and take several minutes to complete. In this example, the file name is overridden from the default.

 java -Xgcpolicy:metronome -Xdump:system:events=vmstop,file=my.dmp

 		::::::::: removed usage info :::::::::
