The LocalSyslogAppender type exposes the following members.

	Name	Description
	LocalSyslogAppender	Initializes a new instance of the LocalSyslogAppender class.

	Name	Description
	ErrorHandler	Gets or sets the IErrorHandler for this appender. (Inherited from AppenderSkeleton.)
	Facility	Syslog facility
	FilterHead	The filter chain. (Inherited from AppenderSkeleton.)
	Identity	Message identity
	Layout	Gets or sets the ILayout for this appender. (Inherited from AppenderSkeleton.)
	Name	Gets or sets the name of this appender. (Inherited from AppenderSkeleton.)
	RequiresLayout	This appender requires a Layout to be set. (Overrides AppenderSkeletonRequiresLayout.)
	Threshold	Gets or sets the threshold Level of this appender. (Inherited from AppenderSkeleton.)

	Name	Description
	ActivateOptions	Initialize the appender based on the options set. (Overrides AppenderSkeletonActivateOptions.)
	AddFilter	Adds a filter to the end of the filter chain. (Inherited from AppenderSkeleton.)
	AddMapping	Add a mapping of level to severity
	Append(LoggingEvent)	Append a bulk array of logging events. (Inherited from AppenderSkeleton.)
	Append(LoggingEvent)	This method is called by the DoAppend(LoggingEvent) method. (Overrides AppenderSkeletonAppend(LoggingEvent).)
	ClearFilters	Clears the filter list for this appender. (Inherited from AppenderSkeleton.)
	Close	Closes the appender and release resources. (Inherited from AppenderSkeleton.)
	DoAppend(LoggingEvent)	Performs threshold checks and invokes filters before delegating actual logging to the subclasses specific [M:Append(LoggingEvent)] method. (Inherited from AppenderSkeleton.)
	DoAppend(LoggingEvent)	Performs threshold checks and invokes filters before delegating actual logging to the subclasses specific [M:Append(LoggingEvent[])] method. (Inherited from AppenderSkeleton.)
	Equals	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	FilterEvent	Test if the logging event should we output by this appender (Inherited from AppenderSkeleton.)
	Finalize	Finalizes this appender by calling the implementation's Close method. (Inherited from AppenderSkeleton.)
	Flush	Flushes any buffered log data. (Inherited from AppenderSkeleton.)
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetSeverity	Translates a log4net level to a syslog severity.
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	IsAsSevereAsThreshold	Checks if the message level is below this appender's threshold. (Inherited from AppenderSkeleton.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	OnClose	Close the syslog when the appender is closed (Overrides AppenderSkeletonOnClose.)
	PreAppendCheck	Called before [M:Append(LoggingEvent)] as a precondition. (Inherited from AppenderSkeleton.)
	RenderLoggingEvent(LoggingEvent)	Renders the LoggingEvent to a string. (Inherited from AppenderSkeleton.)
	RenderLoggingEvent(TextWriter, LoggingEvent)	Renders the LoggingEvent to a string. (Inherited from AppenderSkeleton.)
	ToString	Returns a String that represents the current Object. (Inherited from Object.)

Note
This appender uses the POSIX libc library functions openlog, syslog, and closelog. If these functions are not available on the local system then this appender will not work!

The functions openlog, syslog, and closelog are specified in SUSv2 and POSIX 1003.1-2001 standards. These are used to log messages to the local syslog service.

This appender talks to a local syslog service. If you need to log to a remote syslog daemon and you cannot configure your local syslog service to do this you may be able to use the RemoteSyslogAppender to log via UDP.

Syslog messages must have a facility and and a severity. The severity is derived from the Level of the logging event. The facility must be chosen from the set of defined syslog LocalSyslogAppenderSyslogFacility values. The facilities list is predefined and cannot be extended.

An identifier is specified with each log message. This can be specified by setting the Identity property. The identity (also know as the tag) must not contain white space. The default value for the identity is the application name (from ApplicationFriendlyName).
