I have <code>VisualVM</code> profiling working with my <code>Tomcat</code> application now. I needed to add the following parameters to the tomcat startup:

<pre><code>-Dcom.sun.management.jmxremote.port=8086
-Dcom.sun.management.jmxremote.ssl=false
-Dcom.sun.management.jmxremote.authenticate=false
</code></pre>

Yes we do profile Tomcat applications.

Go to <code>catalina.bat</code> or <code>catalina.sh</code> and this to your <code>JAVA_OPTS</code> (I am using Tomcat 6.0.16):

<pre><code>-Dcom.sun.management.jmxremote=true -Dcom.sun.management.jmxremote.port=9090 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false
</code></pre>

Your <code>JAVA_OPTS</code> should look like

<pre><code>set JAVA_OPTS=%JAVA_OPTS% -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Djava.util.logging.config.file="%CATALINA_BASE%\conf\logging.properties" -Dcom.sun.management.jmxremote=true -Dcom.sun.management.jmxremote.port=9090 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false
</code></pre>

Updated after Ryan comment that it is better to use <code>setenv.sh</code>. This is my <code>setenv.sh</code> for JDK 8. Missing few other settings but good to start with.

<pre><code>SUN_JVM_OPTS="
 -server \
 -XX:MaxMetaspaceSize=3G \
 -XX:+UseConcMarkSweepGC -XX:+CMSParallelRemarkEnabled \
 -XX:+UseCMSInitiatingOccupancyOnly -XX:CMSInitiatingOccupancyFraction=70 \
 -XX:+ScavengeBeforeFullGC -XX:+CMSScavengeBeforeRemark \
 -XX:+UseGCLogFileRotation -XX:NumberOfGCLogFiles=3 -XX:GCLogFileSize=2M \
 -XX:+HeapDumpOnOutOfMemoryError \
 -Dsun.net.inetaddr.ttl=60 \
 -Dcom.sun.management.jmxremote \
 -Dcom.sun.management.jmxremote.port=8480 \
 -Dcom.sun.management.jmxremote.authenticate=false \
 -Dcom.sun.management.jmxremote.ssl=false"


# Set custom application options here
APPLICATION_OPTS="-Dlog4j.configurationFile=patht-to-log/log4j2.xml -Dlog4j.debug=true "

JVM_OPTS="$GENERAL_JVM_OPTS $SUN_JVM_OPTS"
CATALINA_OPTS="$JVM_OPTS $APPLICATION_OPTS"
echo "Tomcat started with settings "$CATALINA_OPTS
</code></pre>

Once you drop the <code>setenv.sh</code> in bin directory, you can see the changes in console on startup.

Here's another step by step tutorial to profile Tomcat applications with Visual VM:

I am using Tomcat 7 and the full configuration reqires more parameters to work.

<pre><code>-Dcom.sun.management.jmxremote=true 
-Dcom.sun.management.jmxremote.port=9090 # port to connect JMX 
-Dcom.sun.management.jmxremote.ssl=false

I would like to profile an application that runs on Tomcat with the VisualVM tool. Unfortunately, when I tell VisualVM to profile Tomcat, Tomcat prints out a couple of messages indicating it is connecting to a profile tool and then simply exits.

Details…

I am using Windows XP, Tomcat 6, VisualVM 1.2.1, and JDK 1.6.0_11.

<ol>
<li>In Visual VM, I right-click on the Tomcat Application and select “Profile”</li>
<li>In the Profiler Tab, I press the Memory button (or the CPU button).</li>
<li>Tomcat exits</li>
</ol>

Note that if I right-click on the Tomcat Application and select “Heap Dump” that seems to work OK.
