This directive specifies the RFC5424 structured-data log format string that
will be used for all logs resulting from traffic passing through the frontend
using this line. If the directive is used in a defaults section, all
subsequent frontends will use the same log format. Please see section 8.2.4

about the RFC5424 structured-data part.
Note : This log format string will be used only for loggers that have set
log format to "rfc5424".
Example :
log-format-sd [exampleSDID@1234\ bytes=\"%B\"\ status=\"%ST\"]
