Full Configuration

`app/config.yml:

fs_log4_php:
  appenders:
    debug_file:
      class: LoggerAppenderRollingFile
      layout: 
        class: LoggerLayoutPattern
      params:
        file: %kernel.root_dir%/logs/debug.log    
        MaxFileSize: 1000KB
        MaxBackupIndex: 5
    error_file:
      class: LoggerAppenderFile
      layout: 
        class: LoggerLayoutPattern
      params:
        file: %kernel.root_dir%/logs/error.log
      threshold: error
    info_file:
      class: LoggerAppenderFile
      layout: 
        class: LoggerLayoutPattern
      params:
        file: %kernel.root_dir%/logs/info.log
      threshold: info       
  rootLogger: 
    level: DEBUG
    appenders: [ debug_file, error_file, info_file ]`

This configuration logs the different log-events (error, info, debug) in different files.

Filter log-events

`app/config.yml:

# ...
# see full-configuration
# ...
    event_info_file:
      class: LoggerAppenderFile
      layout: 
        class: LoggerLayoutPattern
      params:
        file: %kernel.root_dir%/logs/event.log
      filters:
        events:
          class: LoggerFilterStringMatch
          params:
            stringToMatch: event
            acceptOnMatch: true            
  rootLogger: 
    level: DEBUG
    appenders: [ debug_file, error_file, info_file, event_info_file ]`

This config logs all events, which fired by symfony, in a separate event.log. The key part of this config is the filters-section. Only string with the content event are allowed.

Setup your own Logger

This config shows you how to setup a logger, which logs all messages in the mail.log.

`app/config.yml:

# ...
# see full-configuration
# ...
 appenders:
    mail_info:
      class: LoggerAppenderFile
      layout: 
        class: LoggerLayoutPattern
      params:
        file: %kernel.root_dir%/logs/mail.log   
  rootLogger: 
    level: DEBUG
    appenders: [ mail_info ]
  loggers:
    mail:
     level: DEBUG
     appenders: [ mail_file ]
     additivity: false`

To call this logger:

$ths->get('logger')->info('message', array('app'=>'mail'));
