| <H4 class="dtH4">Thread Safety</H4> |
| <P>Public static (<b>Shared</b> in Visual Basic) members of this type are |
| safe for multithreaded operations. Instance members are <b>not</b> guaranteed to be |
| thread-safe.</P> |
| <h4 class="dtH4">Remarks</h4> |
| <p> The appender will fail if you try to write using an event source that doesn't exist unless it is running with local administrator privileges. See also http://logging.apache.org/log4net/release/faq.html#trouble-EventLog </p> |
| <p> The <code>EventID</code> of the event log entry can be set using the <code>EventID</code> property (<a href="log4net.Core.LoggingEvent.Properties.html">Properties</a>) on the <a href="log4net.Core.LoggingEvent.html">LoggingEvent</a>. </p> |
| <p> The <code>Category</code> of the event log entry can be set using the <code>Category</code> property (<b>Properties</b>) on the <b>LoggingEvent</b>. </p> |
| <p> There is a limit of 32K characters for an event log message </p> |
| <p> When configuring the EventLogAppender a mapping can be specified to map a logging level to an event log entry type. For example: </p> |
| <pre class="code"><span class="lang">[XML] |
| </span><mapping> |
| <level value="ERROR" /> |
| <eventLogEntryType value="Error" /> |
| </mapping> |
| <mapping> |
| <level value="DEBUG" /> |
| <eventLogEntryType value="Information" /> |
| </mapping> |
| </pre> |
| <p> The Level is the standard log4net logging level and eventLogEntryType can be any value from the <a href="ms-help://MS.NETFrameworkSDKv1.1/cpref/html/frlrfSystemDiagnosticsEventLogEntryTypeClassTopic.htm">EventLogEntryType</a> enum, i.e.: <ul type="disc"><li><b>Error - </b>an error event</li><li><b>Warning - </b>a warning event</li><li><b>Information - </b>an informational event</li></ul> |
