## Remarks

This interface is created by calling [XtfCreateDebugMonitorClient](/reference/tools/xtf/xtfdebugmonitor/methods/xtfcreatedebugmonitorclient-xtfdebugmonitor-xbox-microsoft-m). The interface allows you to monitor for debug messages being output by a game on a development console. In order to start listening for debug messages call [IXtfDebugMonitorClient::Start](/reference/tools/xtf/xtfdebugmonitor/classes/IXtfDebugMonitorClient/methods/start-ixtfdebugmonitorclient-xtfdebugmonitor-xbox-microsoft-m). Once you have finished listening for debug messages from the console call [IXtfDebugMonitorClient::Stop](/reference/tools/xtf/xtfdebugmonitor/classes/IXtfDebugMonitorClient/methods/stop-ixtfdebugmonitorclient-xtfdebugmonitor-xbox-microsoft-m). The IXtfDebugMonitorClient Interface monitors debug output from a specific process. If you want to read more general debug output from a development console you will need to call [XtfCaptureOutputBegin](/reference/tools/xtf/xtfapi/functions/xtfcaptureoutputbegin-xtfapi-xbox-windows-m).
