Depends on what exactly would you like to see. At a bare minimum you can get rates of garbage generation in the heap per JVM with GC logging: http://blog.ragozin.info/2011/09/hotspot-jvm-garbage-collection-options.html Easiest run-time GUI option is to run jvisualvm/jconsole: http://docs.oracle.com/javase/6/docs/technotes/tools/share/jvisualvm.html Or if you prefer command line data then jstat -gcutil PID msec count https://docs.oracle.com/javase/8/docs/technotes/tools/unix/jstat.html On the OS side common things like pmap or /proc/PID/smaps apply.
