NAME

       Jifty::Manual::Logging - Using and controlling Jifty's logging system

Intro

       Jifty uses the Log4perl module for logging messages, so you can define your own log4perl
       config for logging.

       You can define different behaviour for different log levels. For example, you can send
       mail to administrator when error occurred, or add color to warning messages that are
       logged to the terminal.

Config from config.yml

       Various log level config can be set from etc/config.yml or etc/site_config.yml.

Example

           # vim:filetype=conf:et:
           log4perl.rootLogger = INFO , Screen
           log4perl.logger.MyApp.MailNotifier = WARN, Mailer

           log4perl.appender.LOG1 = Log::Log4perl::Appender::File
           log4perl.appender.LOG1.filename  = apache_fastcgi/logs/
           log4perl.appender.LOG1.mode      = append
           log4perl.appender.LOG1.layout    = Log::Log4perl::Layout::PatternLayout
           log4perl.appender.LOG1.layout.ConversionPattern = %d %p %m %n

           log4perl.appender.Mailer         = Log::Dispatch::Email::MailSend
           log4perl.appender.Mailer.to      = admin@blah.com
           log4perl.appender.Mailer.subject = !!ERROR!!
           log4perl.appender.Mailer.layout  = SimpleLayout

           log4perl.filter.Filter1 = sub { /Plugin/ }
           log4perl.filter.FilterRule       = Log::Log4perl::Filter::Boolean
           log4perl.filter.FilterRule.logic = Filter1
           log4perl.appender.LOG1.Filter    = FilterRule

           log4perl.appender.ScreenColor  = Log::Log4perl::Appender::ScreenColoredLevels
           log4perl.appender.ScreenColor.layout = SimpleLayout

           log4perl.appender.Screen   = Log::Log4perl::Appender::Screen
           log4perl.appender.Screen.layout = SimpleLayout
