Logger Error Log
Logger Error Log provides insights when normal activity logging fails by revealing both failures and routine health checkpoint messages for the WhatsUp Gold logger engine. This view of aggregated logger health journal also traces the various source assemblies where checkpoint, failure messages, and exceptions originate.
Each log message record contains the following data columns:
- . Date and time group for the event message.
- . Name of the main program that owns the message. Typically the name of an executable.
- . Name of the component or library where the log health or exception message originates.
- . Failures and exceptions take the Error severity level.
- . WhatsUp Gold component message, for example, NmEngine. started.
: At the bottom of the Logger Error Log report, the record summary displays the total number of rows matching your filter criteria.
