154 .IX Header "DESCRIPTION"
155 This module provides the default, simple logging functionality for Catalyst.
156 If you want something different set \f(CW\*(C`$c\->log\*(C'\fR in your application module,
160 \& $c\->log( MyLogger\->new );
163 Your logging object is expected to provide the interface described here.
164 Good alternatives to consider are Log::Log4Perl and Log::Dispatch.
166 If you want to be able to log arbitrary warnings, you can do something along
170 \& $SIG{__WARN__} = sub { MyApp\->log\->warn(@_); };
173 however this is (a) global, (b) hairy and (c) may have unexpected side effects.
174 Don't say we didn't warn you.

254 .IX Subsection "abort"
255 Should Catalyst emit logs for this request? Will be reset at the end of
258 *NOTE* This method is not compatible with other log apis, so if you plan
259 to use Log4Perl or another logger, you should call it like this:
262 \& $c\->log\->abort(1) if $c\->log\->can('abort');
265 .IX Subsection "_send_to_log"
267 \& $log\->_send_to_log( @messages );
270 This protected method is what actually sends the log information to \s-1STDERR\s0.
271 You may subclass this module and override this method to get finer control
