This plugin gathers jvm stats via jcmd.
Usage:
JVM_PID=15123 dstat --jvm-full
Minimize the impacts of jcmd and consider using:
dstat --noupdate
For full informations on jcmd see:
- http://docs.oracle.com/javase/7/docs/technotes/tools/solaris/jcmd.html
- https://docs.oracle.com/javase/8/docs/technotes/guides/troubleshoot/tooldescr006.html
This requires the presence of /tmp/hsperfdata_* directory, so
it WON'T WORK if you add -XX:-UsePerfData or -XX:+PerfDisableSharedMem.
