The underlying engine exposes almost everything that occurs internally as simple events, and by having integration with Drools Fusion, you can monitor and manage your business processes using complex event process and even perform direct intervention. There has been some limited work on a BAM console / dashboard as well (on top of the existing reporting that is already supported) but this is still preliminary and won't make it into an out-of-the-box solution for jBPM 5.0.
Improving reporting / BAM capabilities is however on the top of our list for the version after that.
