The SocketReceiver class is a part of the Logback library that can be used to receive log events over a TCP/IP socket. The log events are sent by a SocketAppender running on remote clients.

Here is an example of how you might use the SocketReceiver class in a Logback configuration file to receive log events from a remote client:

<configuration>
  <appender name="SOCKET" class="ch.qos.logback.classic.net.SocketReceiver">
    <port>4560</port>
    <reconnectionDelay>10000</reconnectionDelay>
  </appender>

  <root level="debug">
    <appender-ref ref="SOCKET" />
  </root>
</configuration>

In this configuration file, an appender named "SOCKET" is set up that listens on port 4560 for incoming log events sent by remote clients. The element specifies the port on which the SocketReceiver will listen for incoming log events.

It's important to notice that this example is only creating the server side, you still have to have a remote client that connects to the server and sends the logs.

Please note that, you can refer to the logback documentation for more information and options available, for example about the reconnectionDelay.
