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.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
