Log::Report::Dispatcher::Log4perl - send messages to Log::Log4perl back-end
Log::Report::Dispatcher::Log4perl is a Log::Report::Dispatcher
# start using log4perl via a config file # The name of the dispatcher is the name of the default category. dispatcher LOG4PERL => 'logger' , accept => 'NOTICE-' , config => "$ENV{HOME}/.log.conf"; # disable default dispatcher dispatcher close => 'logger'; # configuration inline, not in file: adapted from the Log4perl manpage my $name = 'logger'; my $outfile = '/tmp/a.log'; my $config = <<__CONFIG; log4perl.category.$name = INFO, Logfile log4perl.logger.Logfile = Log::Log4perl::Appender::File log4perl.logger.Logfile.filename = $outfn log4perl.logger.Logfile.layout = Log::Log4perl::Layout::PatternLayout log4perl.logger.Logfile.layout.ConversionPattern = %d %F{1} %L> %m __CONFIG dispatcher LOG4PERL => $name, config => \$config;
This dispatchers produces output tot syslog, based on the Sys::Log4perl module (which will not be automatically installed for you).
Sys::Log4perl
See documentation in the base class.
The REASONs for a message in Log::Report are names quite similar to the log levels used by Log::Log4perl. The default mapping is list below. You can change the mapping using new(to_level).
TRACE => $DEBUG ERROR => $ERROR ASSERT => $DEBUG FAULT => $ERROR INFO => $INFO ALERT => $FATAL NOTICE => $INFO FAILURE => $FATAL WARNING => $WARN PANIC => $FATAL MISTAKE => $WARN
Log::Report uses text-domains for translation tables. These are also used as categories for the Log4perl infrastructure. So, typically every module start with:
Log::Report
use Log::Report 'my-text-domain', %more_options;
Now, if there is a logger inside the log4perl configuration which is named 'my-text-domain', that will be used. Otherwise, the name of the dispatcher is used to select the logger.
The global $caller_depth concept of Log::Log4perl is broken. That variable is used to find the filename and line number of the logged messages. But these messages may have been caught, rerouted, eval'ed, and otherwise followed a unpredictable multi-leveled path before it reached the Log::Log4perl dispatcher. This means that layout patterns %F and %L are not useful in the generic case, maybe in your specific case.
$caller_depth
%F
%L
See "Constructors" in Log::Report::Dispatcher
The Log::Log4perl infrastructure has all settings in a configuration file. In that file, you should find a category with the NAME.
-Option --Defined in --Default accept Log::Report::Dispatcher 'ALL' charset Log::Report::Dispatcher <undef> config <required> format_reason Log::Report::Dispatcher 'LOWERCASE' locale Log::Report::Dispatcher <system locale> mode Log::Report::Dispatcher 'NORMAL' to_level []
When a SCALAR reference is passed in, that must refer to a string which contains the configuration text. Otherwise, specify an existing FILENAME.
See reasonToLevel().
See "Accessors" in Log::Report::Dispatcher
Returns the Log::Log4perl::Logger object which is used for logging. When there is no specific logger for this DOMAIN (logger with the exact name of the DOMAIN) the default logger is being used, with the name of this dispatcher.
See "Logging" in Log::Report::Dispatcher
Returns a level which is understood by Log::Dispatch, based on a translation table. This can be changed with new(to_level).
example:
use Log::Log4perl qw/:levels/; # by default, ALERTs are output as $FATAL dispatcher Log::Log4perl => 'logger' , to_level => [ ALERT => $ERROR, ] , ...;
