◆ do_log()

void mysql_harness::logging::ExternalHandlerProxy::do_log ( const Record & record )

inlineoverrideprivatevirtual

Log message handler primitive.

This member function is implemented by subclasses to properly log a record wherever it need to be logged. If it is not possible to log the message properly, an exception should be thrown and will be caught by the caller.

Parameters

record Record containing information about the message.

Implements mysql_harness::logging::Handler.

◆ reopen()

void mysql_harness::logging::ExternalHandlerProxy::reopen ( const std::string dst = "" )

inlineoverridevirtual

Request to reopen underlying log sink.

Should be no-op for handlers NOT writing to a file. Useful for log rotation, when the logger got the signal with the request to reopen the file. Provide a destination filename for the old file for file based handlers.

Implements mysql_harness::logging::Handler.
