Log4j logger's

rootcho has asked for the wisdom of the Perl Monks concerning the following question:

in log4jperl what are the differences between :

log4perl.rootLogger
log4perl.logger
log4perl.category
[download]

The only way I was able to direct ERRORS to separate file was to use :

'log4perl.rootLogger' => 'DEBUG, Screen,AppLog',
'log4perl.rootLogger.ERRORS'  => 'ERROR, errorsAppender'
[download]

Next step will be to save errors only at errorsAppender , I think I had to use 'additivity'!?
Other question would be how can I switch off 'Screen' appender on the fly in the code ?

PS> my mistake log4perl.rootLogger.ERRORS, didn't work!!
filter worked, but if you know of a better solution ?

'log4perl.rootLogger' => 'DEBUG, Screen,AppLog,errors',
      'log4perl.filter.MatchErr'   =>   'Log::Log4perl::Filter::LevelM
+atch',
      'log4perl.filter.MatchErr.LevelToMatch'  => 'ERROR',
      'log4perl.filter.MatchErr.AcceptOnMatch' => 'true',

      'log4perl.appender.errors.Filter'   => 'MatchErr',

in log4jperl what are the differences between rootLogger/category/logger This is answered in the introductory Retire your debugger, log smartly with Log::Log4perl!, basically it is hierarchical, rootLogger is the root of all loggers, all loggers inherit from root, and loggers are just another name for categories (in log4j, Loggers deprecated, they are a subclass of Category)	[reply]
