Log::Report::Dispatcher::LogDispatch - send messages to Log::Dispatch back-end


   is a Log::Report::Dispatcher


 use Log::Dispatch::File;
 dispatcher Log::Dispatch::File => 'logger', accept => 'NOTICE-'
   , filename => 'logfile', to_level => [ 'ALERT-' => 'err' ];

 # disable default dispatcher
 dispatcher close => 'logger';


This dispatchers produces output to and Log::Dispatch back-end. (which will NOT be automatically installed for you).

The REASON for a message often uses names which are quite similar to the log-levels used by Log::Dispatch. However: they have a different approach. The REASON of Log::Report limits the responsibility of the programmer to indicate the cause of the message: whether it was able to handle a certain situation. The Log::Dispatch levels are there for the user's of the program. However: the programmer does not known anything about the application (in the general case). This is cause of much of the trickery in Perl programs.

The default translation table is list below. You can change the mapping using new(to_level). See example in SYNOPSIS.

Inherited, see "Constructors" in Log::Report::Dispatcher

Log::Report::Dispatcher::LogDispatch->new($type, $name, %options)

The Log::Dispatch infrastructure has quite a large number of output TYPEs, each extending the Log::Dispatch::Output base-class. You do not create these objects yourself: Log::Report is doing it for you.

The Log::Dispatch back-ends are very careful with validating their parameters, so you will need to restrict the options to what is supported for the specific back-end. See their respective manual-pages. The errors produced by the back-ends quite horrible and untranslated, sorry.

See Log::Dispatch::Output.

charset => CHARSET
locale => LOCALE
max_level => LEVEL

Like min_level.

min_level => LEVEL

Restrict the messages which are passed through based on the LEVEL, so after the reason got translated into a Log::Dispatch compatible LEVEL. The default will use Log::Report restrictions only.

mode => 'NORMAL'|'VERBOSE'|'ASSERT'|'DEBUG'|0..3
to_level => ARRAY-of-PAIRS

See reasonToLevel().
