Hi Ravi,

have you looked at the logging facilities included in Drools,
especially AgendaEventListener? That way you wouldn't have to manually
log activations in the RHS of every rule. Diffing the the names of
available rules versus those collected by the logging seems to me the
most straightforward solution, too.
