Note

Data Hub supports logging to an SEQ log server, which provides a more comprehensive toolset for working with logs.

The Application log link is available from Settings > Utility Toolbar.

The amount of information available for display is based on the Application Log Verbosity setting. The Minimum level drop-down list can then be used to further filter this available information.
