Server Logs

The default location for the server logs is:

Operating System	Logs Folder Location
Windows®	%ProgramData%\MathWorks\webapps\R2024b\logs
Linux®	/local/MathWorks/webapps/R2024b/logs
macOS	/Library/Application Support/MathWorks/webapps/R2024b/logs

The server generates multiple log files, each with a distinct purpose. Depending on the issue you encounter, you may need to review one or more of these log files.

If you configured a different folder location for the server logs, execute webapps-config get logs_path from the system command-line to get the location.

Log File Name	Purpose
webapps_<timestamp>.log	Log file for the service that runs the server.
webapps_launcher_<timestamp>.log	Log file for the service that runs applications.
webapps_launcher_service_start.err	Log file that captures errors associated with starting the service that runs applications.
webapps_launcher_service_start.out	Log file that captures standard output when the service that runs applications fails to start.
webapps_service_start.err	Log file that captures errors when the service that runs the server fails to start.
webapps_service_start.out	Log file that captures standard output when the service that runs the server fails to start.

Note

If you are unable to see log files in the logs folder, check to see if the logs folder has write permissions.
