Monitoring Tomcat Clusters

Hi,
I'm looking for some examples on implementing a summary page on the
current and historical usage of tomcat instances.   I'm mostly
interested in number of user sessions and JVM stats graphed over time.

Basiclly, something exactly like this:
http://people.ee.ethz.ch/~oetiker/webtools/rrdtool/gallery/dgo-01.html

I'm have a decent understanding on how to do it(poll manager, store
results, generate graphs), but I would rather adapt something already
out there rather that do it all from scatch.

Thanks

the monitor can shot the current status and the performance of tomcat
over the last 1K samples. Depending on what your request interval is,
the historic performance may cover a couple of minutes to an hour.

Peter,

Thanks, but I'm from looking over the docs its not clear how I would 
implement a web based status page capable of send alerts, etc.   I know 
JMeter is great for loadtesting/profiling tomcat, but is it designed for 
what I'm looking for?

There's already a GUI monitor for Tomcat 5.0.19 and newer in JMeter.

if you want to graph the cluster, it would be a matter of extending
the monitor sampler to do so.
