## Remarks

This function is used to start listening for debug output from a game on a development console. When you are finished listening for debug output call [IXtfDebugMonitorClient::Stop](/reference/tools/xtf/xtfdebugmonitor/classes/IXtfDebugMonitorClient/methods/stop-ixtfdebugmonitorclient-xtfdebugmonitor-xbox-microsoft-m) to stop listening for output. If you do not call [IXtfDebugMonitorClient::Stop](/reference/tools/xtf/xtfdebugmonitor/classes/IXtfDebugMonitorClient/methods/stop-ixtfdebugmonitorclient-xtfdebugmonitor-xbox-microsoft-m) it may result in resource leakage and an orphaned debugger attachment to the game, this may require a game restart to fix.
