perfino

perfino is a Java Virtual Machine monitoring tool. When you log into perfino, the dashboard shows you if everything is OK, or if something is going wrong.

It gives you fine-grained control over what level of performance is acceptable for your application.

perfino has the ability to monitor hundreds of VMs with a single server. You can organize your VMs into hierarchical groups to keep track of related VMs. The perfino UI shows you aggregate data for each VM group and configuration settings are applied to to entire groups rather than to single VMs.
