+ <p>
+ Tomcat offers an alternative to using remote (or even local) JMX
+ connections while still giving you access to everything JMX has to offer:
+ Tomcat's
+ <a
href="api/org/apache/catalina/manager/JMXProxyServlet.html">JMXProxyServlet</a>.
+ </p>
+
+ <p>
+ The JMXProxyServlet allows a client to issue JMX queries via an HTTP
+ interface. This technique offers the following advantages over using
+ JMX directly from a client program:
+ </p>
+
+ <ul>
+ <li>You don't have to launch a full JVM and make a remote JMX connection
+ just to ask for one small piece of data from a runing server</li>
+ <li>You don't have to know how to work with JMX connections</li>
+ <li>You don't need any of the complex configuration covered in the rest
+ of this page</li>
+ <li>Your client program does not have to be written in Java</li>
+ </ul>
+
+ <p>
+ A perfect example of JMX overkill can be seen in the case of popular
+ server-monitoring software such as Nagios or Ichinga: if you want to
+ monitor 10 items via JMX, you will have to launch 10 JVMs, make 10 JMX
+ connections, and then shut them all down every few minutes. With the
+ JMXProxyServlet, you can make 10 HTTP connections and be done with it.
+ </p>
+
+ <p>
+ You can find out more information about the JMXProxyServlet in the
+ documentation for the
+ <a href="manager-howto.html#Using_the_JMX_Proxy_Servlet">Tomcat
+ manager</a>.
