11719	Create a log file only if some data is written to it	parikshit.nangre@…	Andrey Semashev	"I am creating a log file using 

src::severity_logger< severity_level > m_DbLogger;
logging::add_file_log
(
				
   keywords::auto_flush = true,
   keywords::file_name = m_Settings.LogFileSQL + ""_diagnostics.log"",
   keywords::time_based_rotation = sinks::file::rotation_at_time_point(0, 0,     0),
   keywords::format =

      << "": ["" << boost::log::expressions::attr< severity_level >(""Severity"")
      << ""] "" << boost::log::expressions::smessage
    )
);

It creates a log file before any log goes into it. I want to have that log file ONLY IF some data is written into it. If no log goes into it we dont want to see that log file.

Please suggest a solution for it."	Support Requests	closed	To Be Determined	log	Boost 1.59.0	Problem	worksforme
