Hi David,

I will explain my problem in more details. I am using logback 1.0.7 and slf4j 1.7.5. For building, I use Eclipse IDE, one simple test program to log message and logback.xml as configuration file for parameters. This is how logback.xml looks like.

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<appender name="FILE" class="ch.qos.logback.core.FileAppender">
    <file>myApp.log</file>
    <encoder>
      <pattern>%date [%thread] %level %logger{15} %msg%n</pattern>
    </encoder>
  </appender>
<appender name="SOCKET" class="ch.qos.logback.classic.net.SocketAppender">
    <remoteHost>localhost</remoteHost>
    <port>6000</port>
    <reconnectionDelay>10000</reconnectionDelay>
    <includeCallerData>true</includeCallerData>
  </appender>
<root level="debug">
     <appender-ref ref="FILE" />
    <appender-ref ref="SOCKET" />
 </root>
</configuration>

For testing purpose I use ch.qos.logback.classic.net.SimpleSocketServer, passing 2 arguments as shown on site ie. java ch.qos.logback.classic.net.SimpleSocketServer 6000  src/main/java/chapters/appenders/socket/server1.xml. When localhost is in the place, the messages are sent without problems to server. Also, tested with IP address of another computer in my LAN where I started SimpleSocketServer on that address and also messages are sent without problems. So, the actual problem is when there is some public IP address (i want to send to remote office's server) in remoteHost, building simple stop with executing in Eclipse.
By setting debug="true" attribute of configuration tag in xml and when there is localhost as remoteHost address  I got this:
...
12:28:41,172 |-INFO in ch.qos.logback.core.joran.action.AppenderAction - About to instantiate appender of type [ch.qos.logback.classic.net.SocketAppender]
12:28:41,176 |-INFO in ch.qos.logback.core.joran.action.AppenderAction - Naming appender as [SOCKET]
12:28:41,197 |-INFO in ch.qos.logback.classic.net.SocketAppender[SOCKET] - Starting a new connector thread.
12:28:41,199 |-INFO in ch.qos.logback.classic.net.SocketAppender[SOCKET] - Could not connect to remote logback server at [localhost]. We will try again later. java.net.ConnectException: Connection refused
    at java.net.ConnectException: Connection refused
...

which basically means waiting for server to be up again and will try later to send log message, and running application continues with executing anyway.

But if I put IP address of remote server, process paused here:
...
12:41:35,234 |-INFO in ch.qos.logback.core.joran.action.AppenderAction - About to instantiate appender of type [ch.qos.logback.classic.net.SocketAppender]
12:41:35,239 |-INFO in ch.qos.logback.core.joran.action.AppenderAction - Naming appender as [SOCKET]

What caused that to happens? Is possibly at all to send socket messages to remote server IP address and how I can achieve it?

Hi,

It's not clear what your question is. Is something not working? Are you asking what is the best way to configure it?

What version of logback are you using. And what does your logback.xml look like?

David
