// Shows how to enable Speech SDK trace logging to memory. Memory logger keeps logging into a fixed-size
// memory buffer (a "ring" buffer). At any pointer in time, when an issue occurs, the application
// can dump the whole content of the memory buffer in one of several formats. For example, an
// application using Speech SDK for speech recognition, may want to dump the content of the
// logging memory buffer to file for one or more unexpected CancellationErrorCode values received
// (instead of a recognition result).
// Microsoft may ask you to collect logs using MemoryLogger in order to investigate an issue you reported,
// and will guide you on when to do the dump.
public static void MemoryLoggerWithOrWithoutFilter()
{
// Optional - Apply a filter, such that only traces that contain either one of the
// filter strings will be logged. Microsoft will provide the filter when relevant.
/*
* string[] filters = { "YourFirstString", "YourSecondString" };
* MemoryLogger.SetFilters(filters);
*/
// Turn on logging to memory
MemoryLogger.Start();
// Do your Speech SDK calls here... for example:
SpeechConfig config = SpeechConfig.FromSubscription("YourSubscriptionKey", "YourServiceRegion");
SpeechRecognizer recognizer = new SpeechRecognizer(config);
// Define the full path and name of a log file on your local disk
string logFile = "speech-sdk-log.txt";
// At any time (while still logging or after logging is stopped) you can dump the
// recent traces from memory to a file:
MemoryLogger.Dump(logFile);
// Or dump to any object that is derived from System.IO.TextWriter. For example, System.Console.Out,
// which will enable logging to your console windows:
MemoryLogger.Dump(System.Console.Out);
// Or dump to a vector of strings, and see the results on the console:
List <string> messages = MemoryLogger.Dump().ToList <string>();
Console.WriteLine("Here are the logs we captured:");
foreach (string message in messages)
{
Console.Write(message);
}
// Stop logging to memory
MemoryLogger.Stop();
// Clear filters if previously set
MemoryLogger.SetFilters();
