JAMon 2.4 has been released. Added the capability of adding listeners that developers can write. JAMon ships with the JAMonBufferListener that can be used to track details such as when a new max occurs, or when an event is 3 standard deviations from the median etc. The JAMon war now comes with the ability to view this data.
Here is a live demo:
