11720,Problem with 2 loggers in one class,parikshit.nangre@…,Andrey Semashev,"Hello,

i am using src::severity_logger< severity_level > and facing some issue.
Here is the issue and code -

I have 2 loggers in a class as class members

class A
{
src::severity_logger< severity_level > m_DbLogger;
src::severity_logger< severity_level > m_DiagnosticsLogger;

}

i want to use 2 loggers, m_DbLogger for logs related to stored procedures and
m_DiagnosticsLogger to log if any error occured while executing some stored procedure.

i am usign following code -


logging::add_file_log
(
	keywords::auto_flush = true,
	keywords::file_name = mylogfile + "".log"",
	keywords::time_based_rotation = sinks::file::rotation_at_time_point(0, 0, 0),
	keywords::format =
	(
		boost::log::expressions::stream
		<< boost::log::expressions::format_date_time< boost::posix_time::ptime >(""TimeStamp"", ""%Y-%m-%d %H:%M:%S"")
		<< "": ["" << boost::log::expressions::attr< severity_level >(""Severity"")
		<< ""] "" << boost::log::expressions::smessage
	)
);

logging::add_file_log
(

	keywords::auto_flush = true,
	keywords::file_name = mylogfile + ""_diagnostics.log"",
	keywords::time_based_rotation = sinks::file::rotation_at_time_point(0, 0, 0),
	keywords::format =
	(
		boost::log::expressions::stream
		<< boost::log::expressions::format_date_time< boost::posix_time::ptime >(""TimeStamp"", ""%Y-%m-%d %H:%M:%S"")
		<< "": ["" << boost::log::expressions::attr< severity_level >(""Severity"")
		<< ""] "" << boost::log::expressions::smessage
	)
);

i want to use mylogfile + "".log"" for m_DbLogger and want to use mylogfile + ""_diagnostics.log"" for m_DiagnosticsLogger
but when try to log with -

LOG_MAIN_INFO_EX(m_DbLogger, ""/* try #"" << i << "" "" << (ws.elapsed() / 1000) << "" [ms]*/ "" << statement);

where macro is defined as -
#define LOG_MAIN_INFO_EX(logger, _str) BOOST_LOG_SEV(logger, info) << _str;

In this case the log goes in both file and not just in mylogfile.log but also in mylogfile_diagnostics.log file as well.


I want the log to go in just 1 file ie in mylogfile.log.

And when i call LOG_MAIN_ERROR_EX(m_DiagnosticsLogger, ""Statement : "" << statement); where macro is defined as -
#define LOG_MAIN_ERROR_EX(logger, _str) BOOST_LOG_SEV(logger, error) << _str;

in this case i want this log to go only in mylogfile_diagnostics.log and not in mylogfile.log 

Basically i want to connect following block to m_DbLogger
logging::add_file_log
(
	keywords::auto_flush = true,
	keywords::file_name = mylogfile + "".log"",
	keywords::time_based_rotation = sinks::file::rotation_at_time_point(0, 0, 0),
	keywords::format =
	(
		boost::log::expressions::stream
		<< boost::log::expressions::format_date_time< boost::posix_time::ptime >(""TimeStamp"", ""%Y-%m-%d %H:%M:%S"")
		<< "": ["" << boost::log::expressions::attr< severity_level >(""Severity"")
		<< ""] "" << boost::log::expressions::smessage
	)
);

and want to connect following bloack to m_DiagnosticsLogger
logging::add_file_log
(

	keywords::auto_flush = true,
	keywords::file_name = mylogfile + ""_diagnostics.log"",
	keywords::time_based_rotation = sinks::file::rotation_at_time_point(0, 0, 0),
	keywords::format =
	(
		boost::log::expressions::stream
		<< boost::log::expressions::format_date_time< boost::posix_time::ptime >(""TimeStamp"", ""%Y-%m-%d %H:%M:%S"")
		<< "": ["" << boost::log::expressions::attr< severity_level >(""Severity"")
		<< ""] "" << boost::log::expressions::smessage
	)
);

Please update me asap.
