</PRE>
<P>
Sends <A HREF="../../../../org/apache/log4j/spi/LoggingEvent.html" title="class in org.apache.log4j.spi"><CODE>LoggingEvent</CODE></A> objects to a set of remote log servers,
usually a <A HREF="../../../../org/apache/log4j/net/SocketNode.html" title="class in org.apache.log4j.net"><CODE>SocketNodes</CODE></A>.
<p>Acts just like <A HREF="../../../../org/apache/log4j/net/SocketAppender.html" title="class in org.apache.log4j.net"><CODE>SocketAppender</CODE></A> except that instead of
connecting to a given remote log server,
<code>SocketHubAppender</code> accepts connections from the remote
log servers as clients. It can accept more than one connection.
When a log event is received, the event is sent to the set of
currently connected remote log servers. Implemented this way it does
not require any update to the configuration file to send data to
another remote log server. The remote log server simply connects to
the host and port the <code>SocketHubAppender</code> is running on.
<p>The <code>SocketHubAppender</code> does not store events such
that the remote side will events that arrived after the
establishment of its connection. Once connected, events arrive in
order as guaranteed by the TCP protocol.
<p>This implementation borrows heavily from the <A HREF="../../../../org/apache/log4j/net/SocketAppender.html" title="class in org.apache.log4j.net"><CODE>SocketAppender</CODE></A>.
<p>The SocketHubAppender has the following characteristics:
<ul>
<p><li>If sent to a <A HREF="../../../../org/apache/log4j/net/SocketNode.html" title="class in org.apache.log4j.net"><CODE>SocketNode</CODE></A>, logging is non-intrusive as
far as the log event is concerned. In other words, the event will be
logged with the same time stamp, <A HREF="../../../../org/apache/log4j/NDC.html" title="class in org.apache.log4j"><CODE>NDC</CODE></A>,
location info as if it were logged locally.
<p><li><code>SocketHubAppender</code> does not use a layout. It
ships a serialized <A HREF="../../../../org/apache/log4j/spi/LoggingEvent.html" title="class in org.apache.log4j.spi"><CODE>LoggingEvent</CODE></A> object to the remote side.
<p><li><code>SocketHubAppender</code> relies on the TCP
protocol. Consequently, if the remote side is reachable, then log
events will eventually arrive at remote client.
<p><li>If no remote clients are attached, the logging requests are
simply dropped.
<p><li>Logging events are automatically <em>buffered</em> by the
native TCP implementation. This means that if the link to remote
client is slow but still faster than the rate of (log) event
production, the application will not be affected by the slow network
connection. However, if the network connection is slower then the
rate of event production, then the local application can only
progress at the network rate. In particular, if the network link to
the the remote client is down, the application will be blocked.
<p>On the other hand, if the network link is up, but the remote
client is down, the client will not be blocked when making log
requests but the log events will be lost due to client
unavailability.
<p>The single remote client case extends to multiple clients
connections. The rate of logging will be determined by the slowest
link.
<p><li>If the JVM hosting the <code>SocketHubAppender</code> exits
before the <code>SocketHubAppender</code> is closed either
explicitly or subsequent to garbage collection, then there might
be untransmitted data in the pipe which might be lost. This is a
common problem on Windows based systems.
<p>To avoid lost data, it is usually sufficient to <A HREF="../../../../org/apache/log4j/net/SocketHubAppender.html#close()"><CODE>close()</CODE></A>
the <code>SocketHubAppender</code> either explicitly or by calling
the <A HREF="../../../../org/apache/log4j/LogManager.html#shutdown()"><CODE>LogManager.shutdown()</CODE></A> method before
exiting the application.
