> API to flush appenders
> ----------------------

>                 Key: LOG4NET-511
>                 URL: https://issues.apache.org/jira/browse/LOG4NET-511
>             Project: Log4net
>          Issue Type: Wish
>          Components: Appenders, Core
>    Affects Versions: 1.2.15
>         Environment: NA
>            Reporter: Joe
>            Priority: Minor

> I would like to see an API that flushes any appenders that have buffered data. E.g. a method LogManager.Flush().  An application might call such a method at regular intervals, e.g. on a Timer.
> A naive implementation with the current log4net would iterate through appenders, looking for those that support flushing, and call the appender's flush method, e.g.:
>     foreach (IAppender appender in 
>              LogManager.GetRepository().GetAppenders())
>     {
>         BufferingAppenderSkeleton bas = appender 
>                         as BufferingAppenderSkeleton;  
>         if (bas != null) bas.Flush();
>     }
> But (a) I'm not sure this is thread-safe and (b) there are potentially other appenders that may want to be able to flush data (e.g. a TextWriterAppender with ImmediateFlush = false).
> The request consists of:
> - Add an interface, IFlushableAppender or equivalent, with a single method Flush().
> - Implement this interface in all relevant appenders (BufferingAppenderSkeleton, TextWriterAppender, ...)
> - Add a thread-safe static Flush() method to LogManager.
