At the system level, you can look at not just how much memory a process is using, but where it is using the memory, in detail. Use pmap…
First find the process id:
[root@jbtest ~]# ps -ef | grep java bbod 11987 11929 0 Feb29 ? 00:04:03 /opt/jdk/bin/java -Dprogram.name=run.sh -server -Xms2048m -Xmx2048m -XX:MaxPermSize=256m -Dcom.test.cookiedomain=test.com -Dtangosol.mode=prod -XX:+DisableExplicitGC -XX:+PrintGCDetails -XX:NewRatio=3 -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/opt/etc/heap -Dsun.rmi.dgc.client.gcInterval=1800000 -Dsun.rmi.dgc.server.gcInterval=1800000 -Dtangosol.coherence.log.level=2 -Dtangosol.management=all -Dtangosol.management.remote=true -Dtangosol.management.readonly=true -verbose:gc -Xloggc:/opt/logs/gc.log.app.201202291332 -XX:+PrintGCDateStamps -XX:+PrintGCDetails -Dorg.apache.catalina.STRICT_SERVLET_COMPLIANCE=false -Djava.net.preferIPv4Stack=true -Djava.endorsed.dirs=/opt/jboss/lib/endorsed -classpath /opt/jboss/bin/run.jar:/opt/jdk/lib/tools.jar org.jboss.Main -c app -P /opt/jboss/server/app/lib/db.prop -Djboss.server.log.dir=/opt/logs -b jbtest.bsd.prodcc.net -Djboss.bind.address=ui.jbtest -Djboss.svr.name=jbtest -Djboss.env=production -Djboss.app=app
The run pmap as follows against that process ID:
[root@jbtest ~]# pmap -x 11987 11987: /opt/jdk/bin/java -Dprogram.name=run.sh -server -Xms2048m -Xmx2048m -XX:MaxPermSize=256m -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/opt/etc/heap
