Hi 

Please have a look at this article:-

Link:-http://therealcq.blogspot.in/2014/05/cq5aem-how-do-i-detect-from.html

// How do I detect from a SlingServlet whether it is running on the Master or Slave instance 

Basically you can add a message in a log like this: 

    final String isMaster = repository.getDescriptor("crx.cluster.master");
    return StringUtils.isNotBlank(isMaster) && Boolean.parseBoolean(isMaster);

I hope this would help you.
