| Method | Description |
| - | - |
| [Start](https://docs.xbox.com/reference/tools/xtf/xtfdebugmonitor/classes/IXtfDebugMonitorClient/methods/start-ixtfdebugmonitorclient-xtfdebugmonitor-xbox-microsoft-m.md) | Starts listening for debug output from the development console. |

## Requirements

**Header:** xtfdebugmonitor.h

**Library:** xtfdebugmonitor.lib

**Supported platforms:** Windows (for XBOX console tools)

## Remarks

This interface is created by calling [XtfCreateDebugMonitorClient](https://docs.xbox.com/reference/tools/xtf/xtfdebugmonitor/methods/xtfcreatedebugmonitorclient-xtfdebugmonitor-xbox-microsoft-m.md). 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](https://docs.xbox.com/reference/tools/xtf/xtfdebugmonitor/classes/IXtfDebugMonitorClient/methods/start-ixtfdebugmonitorclient-xtfdebugmonitor-xbox-microsoft-m.md). Once you have finished listening for debug messages from the console call [IXtfDebugMonitorClient::Stop](https://docs.xbox.com/reference/tools/xtf/xtfdebugmonitor/classes/IXtfDebugMonitorClient/methods/stop-ixtfdebugmonitorclient-xtfdebugmonitor-xbox-microsoft-m.md). 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](https://docs.xbox.com/reference/tools/xtf/xtfapi/functions/xtfcaptureoutputbegin-xtfapi-xbox-windows-m.md).
