The source name is used to identify traces. It is used by a SourceFilter to determine whether a trace listener should produce the trace. The recommended practice is to use the name of the application for the source name.
It is not necessary to create a new TraceSource instance for each trace request. Create one TraceSource instance and use it for all trace requests for the application.
