Enterprise monitoring using JMX

Hello,

So, my company has a lot of J2EE/Tomcat servers running on java 1.6. I'm trying to find a way to monitor them all via JMX from a centralized system, which would be accessible to multiple users (web based, ideally).

Based on my understanding of JMX, it should be possible to extract the data we need from each JVM. I have been using JConsole to do this on an ad-hoc basis when we have problems with a particular JVM and it's great.

But I can't seem to find any good software for doing enterprise-wide monitoring and long-term data collection... can anyone suggest a good package, either free/open-source (ideally) or commercial?

Basically, I want to be able to:

* collect CPU, memory, DB (hibernate), HTTP request stats, etc. via JMX and archive it

* view graphs of the above

* ideally, we could also receive email alerts if certain conditions were met, e.g. memory almost full.

As a side note:

We're already using Zenoss (http://www.zenoss.com) to monitor the OS-level stuff and we really like it, but we need more visibility into each JVM (we have multiple JVMs per physical server). As far as I can tell, Zenoss doesn't support JMX monitoring... but has anyone found a way to make this work? If so, I'd love to hear about it, since this would be ideal for me.
