Remarks

The EventID of the event log entry can be set using the EventLogEventID property (Properties) on the LoggingEvent.

There is a limit of 32K characters for an event log message

When configuring the EventLogAppender a mapping can be specified to map a logging level to an event log entry type. For example:

[XML]
<mapping>
    <level value="ERROR" />
    <eventLogEntryType value="Error" />
</mapping>
<mapping>
    <level value="DEBUG" />
    <eventLogEntryType value="Information" />
</mapping>

The Level is the standard log4net logging level and eventLogEntryType can be any value from the EventLogEntryType enum, i.e.:

• Error - an error event
• Warning - a warning event
• Information - an informational event
