Open Source, Multiple JVM Monitor web application options?
I'm looking for an open source web application to monitor several JVM's over several servers. I've done some searching and found multiple options that are failing each in their own way.

I need it to:<br>
1. Be a web application<br>
2. Monitor several JVM's across multiple servers<br>
3. Specifically monitor Heap/Perm Gen memory space<br>
4. Be able to set off an email alert based on thresholds for both of these.<br>

I found another question posted 2 years ago that is still updated, though it specifically calls out Tomcat, and doesn't allow for JVM's alone:
http://stackoverflow.com/questions/242958/best-tools-to-monitor-tomcat

Looking into JavaMelody and a few others, from what I gather, they're not able to monitor multiple JVM's across multiple servers.
