Server Logs

The default location for the server logs is:

Windows®

%ProgramData%\MathWorks\webapps\R2020b\logs

Linux®

/local/MathWorks/webapps/R2020b/logs

macOS

/Library/Application Support/MathWorks/webapps/R2020b/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.
