internal package Foswiki::Logger::Compatibility internal package Foswiki::Logger::Compatibility is a Foswiki::Logger configure.
Plain file implementation of the Foswiki Logger interface. Mostly
compatible with Foswiki 1.0.0 log files, except that dates
are recorded using ISO format, and include the time, and it dies when
a log can't be written (rather than printing a warning).
This logger implementation maps groups of levels to a single logfile, viz. debug messages are output to $Foswiki::cfg{DebugFileName}
info messages are output to $Foswiki::cfg{LogFileName}
warning, error, critical, alert, emergency messages are output to $Foswiki::cfg{WarningFileName}.
error, critical, alert, and emergency messages are also written to standard error (the webserver log file, usually)
ObjectMethod log($level, @fields) StaticMethod eachEventSince($time, $level) → $iterator info messages are output together.
warning, error, critical, alert, emergency messages are output together.
