Oracle JDK ships with a nice tool called jVisualVM, see http://docs.oracle.com/javase/7/docs/technotes/guides/visualvm/ for details.

When starting up you can attach to local running java processes, select the one for Neo4j. This gives you access to a lot of JVM internal information, memory consumption is one of them.
