The TraceInformation method provides an informational message intended to be read by users and not by tools.

TraceInformation(String, Object[]) calls the TraceEvent(TraceEventType, Int32, String, Object[]) method, setting eventType to TraceEventType.Information and passing the message content as an object array with formatting information. The TraceEvent(TraceEventType, Int32, String, Object[]) method in turn calls the TraceEvent(TraceEventCache, String, TraceEventType, Int32, String, Object[]) method of each trace listener.
