The SimpleSocketServer 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 SimpleSocketServer class in a Java program to receive log events over a socket connection:

import ch.qos.logback.classic.net.SimpleSocketServer;

public class LogServer {
    public static void main(String[] args) {
        SimpleSocketServer server = new SimpleSocketServer(8080);
        server.start();
    }
}

In this example, a SimpleSocketServer object is created and configured to listen on port 8080 for incoming log events sent over a socket connection. The server is then started to start listening 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.

You can check logback documentation for more information and options available.
