| <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> |
| <blockquote class="dtBlock"><b>Note</b>��� This appender uses the POSIX libc library functions <code>openlog</code>, <code>syslog</code>, and <code>closelog</code>. If these functions are not available on the local system then this appender will not work! </blockquote> |
| <p> The functions <code>openlog</code>, <code>syslog</code>, and <code>closelog</code> are specified in SUSv2 and POSIX 1003.1-2001 standards. These are used to log messages to the local syslog service. </p> |
| <p> 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 <a href="log4net.Appender.RemoteSyslogAppender.html">RemoteSyslogAppender</a> to log via UDP. </p> |
| <p> 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 <a href="log4net.Appender.LocalSyslogAppender.SyslogFacility.html">LocalSyslogAppender.SyslogFacility</a> values. The facilities list is predefined and cannot be extended. </p> |
| <p> An identifier is specified with each log message. This can be specified by setting the <a href="log4net.Appender.LocalSyslogAppender.Identity.html">Identity</a> property. The identity (also know as the tag) must not contain white space. The default value for the identity is the application name (from <a href="log4net.Util.SystemInfo.ApplicationFriendlyName.html">ApplicationFriendlyName</a>). </p> |
