Hi,
I'd like to know if it's possible to configure an appender (or a
forward appender) that can do the following:
1. Buffer all incoming log messages, in a loss-less manner
2. Flush the buffer when it reaches N messages, OR when a timeout of T
seconds reached since the first message (since app start or last flush)
3. Flush the buffer if the application is terminated.
Do you think this is achievable?
Thanks,

It's easily done. I had to do this for a Remoting appender, but you
could easily adapt it to an buffered appender, or maybe add it to the
base class. You can us a different timer, or even a thread if you have
limitations on using the thread pool.

public TimedRemotingAppender()

FlushPeriod = 10;
timer = new Timer(FlushBuffer);
}
/// <summary>
/// The period, in seconds, at which the buffer is sent
regardless of being full
/// </summary>
public int FlushPeriod { get; set; }
private readonly Timer timer;
private void FlushBuffer(object state) { Flush(); }
protected override void Append(LoggingEvent loggingEvent)
{
base.Append(loggingEvent);
timer.Change(FlushPeriod * 1000, Timeout.Infinite);
}
}
