#12364: In boost::log, how to re-connect to a remote server (like logstash)?

------------------------------+---------------------
 By using boost::asio::ip::tcp::iostream and boost::log, I am trying to
 send log records to a remote server like logstash. But I need to handle
 the network disconnection/reconnection. Unfortunately, I did not find any
 way for tcp::iostream.

     Is it possible to get a notification or exception when the tcp
 connection is broken?
     Can I use ip::tcp::socket instead of tcp::iostream in boost::log?
 Thank you.

 My code looks like:

 {{{
 typedef boost::log::sinks::asynchronous_sink<
 boost::log::sinks::text_ostream_backend > tcp_sink;
 boost::shared_ptr< tcp_sink > networkSink;

 // init tcp stream
 boost::shared_ptr< sinks::text_ostream_backend > backend =
     boost::make_shared< sinks::text_ostream_backend >();

 boost::shared_ptr< boost::asio::ip::tcp::iostream > stream =
 boost::make_shared< boost::asio::ip::tcp::iostream >();
 stream->connect("logstash", "1111");


 backend->add_stream(stream);

 networkSink = boost::make_shared< tcp_sink >();
 networkSink->set_formatter(fmt);
 networkSink->set_filter(severity <= severityThreshold);
 networkSink = boost::make_shared<tcp_sink>(backend );
 logging::core::get()->add_sink(networkSink);


 }}}
