Understanding the Event Log Components

The components of the Event Log are standards defined by Windows. Figure 16–1 illustrates the Event Log components when shown through the Event Viewer.

Table 16–3 describes how Progress uses the Event Log columns.

Table 16–3: How Progress Uses Event Log Components
This column . . .
includes this information . . .
Date
Date the event occurred.
Time
Time the event occurred.
Source
Source of the event. This is the name of the connected Progress database, if a database is connected. If no database is connected, then “Progress” is listed.
If you are using the Progress AppServer, “Progress” is also the default source for Progress AppServer messages; however, you can override the default source name by specifying the -logname application broker startup parameter.
Category
To help you isolate the cause of the message displayed in the Event Log, Progress supports 16 event categories. The event categories are: AIW, APPBROKER, APPSERVER, APW, BACKUP, BIW, DATASERVER, MON, OIBRKR, OIDRVR, Progress, RFUTIL, SERVER, SHUT, USER, and WDOG. When no database is connected, Progress is specified as the category.
The APPBROKER and APPSERVER categories appear in the Event Log only when messages are logged by the Progress AppServer application broker and application server, respectively.
All categories reside in a file called category.dll. These categories correspond to the existing categories of events that are displayed in the progress.lg file (application broker and application server events are displayed in the AppServer log file, proapsv.lg).
(Note that DATASERVER is not included as a category in the standard progress.lg file.)
Event
Associates to the Progress message that was generated. These are the same message numbers that are displayed in the standard database .lg file.
User
Identifies the user logged in to the Windows workstation where the event occurred.
Computer
Identifies the name of the Windows workstation where the event occurred. The Event Viewer enables you to get more information about events by double-clicking on any event.

You can view additional information about an event by double-clicking on it. Windows displays the Event Detail screen, as shown in Figure 16–2.
