12364	In boost::log, how to re-connect to a remote server (like logstash)?	xinyan.zhang@…	Andrey Semashev	"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);
