JVM Monitoring

Couple of our applications are using Tomcat server. JMeter was used as load testing tool. To monitor Java memory, I used two options. One is JMX(Java Management Extensions) console and Psi-Probe.

To implement those options, you should add following entries into catalina.sh

set CATALINA_OPTS=-Dcom.sun.management.jmxremote \
-Dcom.sun.management.jmxremote.port=9005 \
-Dcom.sun.management.jmxremote.ssl=false \
-Dcom.sun.management.jmxremote.authenticate=false

To access JMX console,Enter command ==> [java_installation]\bin\jconsole hostname:port
To use Probe, you need to deploy in tomcat server instance and then access the probe application.
