Abstract

A dataflow program defining actors that pass tokens from one to another via connections is processed by causing one or more processors to access and execute instructions of the dataflow program. As instructions of the dataflow program are being executed, a first set of trace records is created that represents a sequence of events (e.g., token production/consumption, actor state change, or action firing). A first subset of the trace records is displayed and one of these is selected. The first set is processed to identify, based on definitions specified by the dataflow program, a second set of trace records, of which a subset is displayed.
