We provide a DSL for the analysis of test platform execution logs of Wireless Sensor Networks. It is based on novel operators, which are provided for the analysis. Traces are represented by sets of event. An event is an entry in the trace, represented by a tuple (hash) of key-value pairs, minimally including a node identifier and a type. The DSL is used to describe events. A log is loaded and parsed, checking basic constraints of events. Subsequently, the DSL allows for analyzing the event set created from the log and processing it.
