Predicate allowing the problem requestor to signal whether or not it is currently
interested by problem reports. When answering false, problem will
not be discovered any more until the next iteration.
This  predicate will be invoked once prior to each problem detection iteration.
Returns:
boolean - indicates whether the requestor is currently interested by problems./**
