In addition to the OpenEdge database log, the OpenEdge Server writes events to the Windows Event Log. The Event Log is the object that enables Windows users to view the status of application, security, and system processes, and to view their associated events. The OpenEdge database is an application process that writes events to the Application Event Log. You use the Event Viewer to see the Event Log's contents. You can customize the Event Viewer so that it displays only the event types that you want to view. You access the Event Viewer through the Administrative Tools program group. For a list of Windows operating systems currently supported by OpenEdge, see OpenEdge Getting Started: Installation and Configuration.

The components that enable OpenEdge services to log messages to the Application event log database are described in the table below.
