HeapAudit is not a monitoring tool, but rather an engineering tool that collects actionable data – information sufficient for directly making code change improvements. It is created for the real world, applicable to live running production servers.

HeapAudit is a foursquare open source project designed for understanding JVM heap allocations. It is implemented as a Java agent built on top of ASM.

Looks really awesome. I’m probably going to try this out tomorrow on some $ORK systems.
