2. In Probe, click on the Cluster tab.

An error message which says, "Cluster information is only available to
Tomcat 5.5.x with enabled cluster support."

This is hardly a probe issue, as Tomcat 6 doesn't seem to provide enough 
clustering 
JMX beans (as opposed to Tomcat 5.5)...

I understand tomcat6.x lacks/missing some JMX beans to extract cluster 
information. Is there any other solution for viewing cluster information?, 
anyone know of other tools?

Renaming 2.2 milestone to 2.2.0.

Until Tomcat exposes cluster information via JMX, this appears to be 
impossible.  Maybe someone could write a library that does this.

Delayed.

Although Tomcat6 does not provide cluster information via JMX, Tomcat7 does: 
http://tomcat.apache.org/tomcat-7.0-doc/cluster-howto.html#Monitoring_your_Clust
er_with_JMX

I believe we could skip the support for Tomcat6 and aim for Tomcat7.

It's true that Tomcat 7 exposes some information, but Tomcat 5.5 had more:
http://tomcat.apache.org/tomcat-5.5-doc/cluster-howto.html#Monitoring_your_Clust
er_with_JMX
The ClusterSender and ClusterReceiver are important, but they're missing in 
Tomcat 7's MBeans.  I'll set up a test cluster sometime soon and see if enough 
information is available through the JMX Console to implement this for Tomcat 7.

Anyway, I've filed Tomcat 7 cluster support as issue 267.

When it will be released, can I see the code which could act as patch for me.
