I'm using ubuntu 14.04 with the included boost 1.54 and I'm trying to set up a syslog sink. I've cut this from the samples and added "ident". void init_syslog() { boost::shared_ptr< boost::log::core > core = boost::log::core::get(); // Create a backend boost::shared_ptr< sinks::syslog_backend > backend(new sinks::syslog_backend( keywords::facility = sinks::syslog::local0, keywords::use_impl = sinks::syslog::native, keywords::ident = "mqtt-proxy" )); // Set the straightforward level translator for the "Severity" attribute of type int backend->set_severity_mapper(sinks::syslog::direct_severity_mapping< int >("Severity")); // Wrap it into the frontend and register in the core. // The backend requires synchronization in the frontend. core->add_sink(boost::make_shared< sink_t >(backend)); } The logs end up in syslog but I cant prefix those by program name (and processnumber ) - I've expected the logs to be marked as 'mqtt-proxy' I get logs like Sep 29 03:47:40 ubuntu : ad569c57-780a-431b-bde3-7ede49e7c77f, bridge create but what I would like is similar to Sep 29 03:47:40 ubuntu mqtt-proxy: ad569c57-780a-431b-bde3-7ede49e7c77f, bridge create Am I missing something or is ident not supported? /svante
