Eigenschaftenwert

Der Name, der im Ereignisprotokoll als Quelle dieses Eintrags registriert ist.

Hinweise

Die Ereignisquelle gibt an, wodurch das Ereignis protokolliert wurde. Häufig ist dies der Name der Anwendung oder, bei großen Anwendungen, der Name einer Unterkomponente. Anwendungen und Dienste schreiben in das Anwendungsprotokoll oder ein benutzerdefiniertes Protokoll und sind somit Quellen für diese Protokolle. Gerätetreiber schreiben i. d. R. in das Systemprotokoll.
