<p>Monitoring is a key aspect of system administration. Looking inside a
running server, obtaining some statistics or reconfiguring some aspects of
an application are all daily administration tasks.</p>

<section name="Enabling JMX Remote">
<p>The Sun website includes the list of options and how to configure JMX Remote on Java 5:
<a href="http://docs.oracle.com/javase/1.5.0/docs/guide/management/agent.html">
http://docs.oracle.com/javase/1.5.0/docs/guide/management/agent.html</a>.
</p>
<p>The following is a quick configuration guide for Java 5:</p>
<p>Add the following parameters to your Tomcat startup script:
<source>
set CATALINA_OPTS=-Dcom.sun.management.jmxremote \
-Dcom.sun.management.jmxremote.port=%my.jmx.port% \
-Dcom.sun.management.jmxremote.ssl=false \
-Dcom.sun.management.jmxremote.authenticate=false
</source>
</p>
<p>
<ol>
<li>If you require authorization, add and change this :
<source>
-Dcom.sun.management.jmxremote.authenticate=true \
-Dcom.sun.management.jmxremote.password.file=../conf/jmxremote.password \
-Dcom.sun.management.jmxremote.access.file=../conf/jmxremote.access \
</source>
</li>
<li>edit the access authorization file <em>$CATALINA_BASE/conf/jmxremote.access</em> :
<source>
monitorRole readonly
controlRole readwrite
</source>
</li>
<li>edit the password file <em>$CATALINA_BASE/conf/jmxremote.password</em> :
<source>
monitorRole tomcat
controlRole tomcat
</source>
<b>Tip</b>: The password file should be read-only and only accessible by the
operating system user Tomcat is running as.
</li>
</ol>
<b>Note:</b>The JSR 160 JMX-Adaptor opens a second data channel on a random
port. That is a problem when you have a local firewall installed.<br/>
</p>

<section name="Manage Tomcat with JMX remote Ant Tasks">
<p>To simplify JMX usage with Ant 1.6.x, a set of tasks is provided that may
be used with antlib.</p>
<p><b>antlib</b>: Copy your catalina-ant.jar from $CATALINA_HOME/lib to $ANT_HOME/lib.</p>
