Debug/logging: $wgDebugLogGroups
Direct wfDebugLog() output for certain groups to files other than $wgDebugLogFileManual:$wgDebugLogFile.
導入されたバージョン: 1.5.0 (r10598)
除去されたバージョン: 使用中
可能な値: array of log group keys to filenames
既定値: array()
他の設定: アルファベット順 | 機能順


Set to an array of log group keys to filenames. If set, wfDebugLog() output for that group will go to that file instead of the regular $wgDebugLogFileManual:$wgDebugLogFile. Useful for enabling selective logging in production.

If a group is configured in $wgDebugLogGroups, then all debug messages with the according group key will be logged to that file, also if $wgDebugLogFile is not set! With other words: If a group key is configured in $wgDebugLogGroups, messages will be written, even if an empty value of $wgDebugLogFile generally disables debugging.

Log destinations may be one of the following:

  • false to completely remove from the output, including from $wgDebugLogFile.
  • string values specifying a filename or URI.
  • associative array with keys:
    • 'destination' desired filename or URI.
    • 'sample' an integer value, specifying a sampling factor (optional)
    • 'level' A \Psr\Log\LogLevel constant, indicating the minimum level log (optional, since 1.25)

When $wgMWLoggerDefaultSpi is set to a non-default value, $wgDebugLogGroups will probably be ignored, and the method of configuring log files will be determined by whatever logging system is invoked by $wgMWLoggerDefaultSpi.


この例では、グループ「ConfirmEditExtension」のデバッグ メッセージは「ext_confirmedit.log」に、「FCKeditor」および「FCKeditorExtension」のデバッグ メッセージは「ext_fckeditor.log」に、それぞれ出力されます。

$wgDebugLogGroups = array(
	'ConfirmEditExtension'	=> $IP . '/../../home/debug-ext_confirmedit.log',
	'SpamRegex'		=> $IP . '/../../home/debug-spam.log',


$wgDebugLogGroups['redis'] = '/var/log/mediawiki/redis.log';


 $wgDebugLogGroups['memcached'] = array(
     'destination' => '/var/log/mediawiki/memcached.log',
     'sample' => 1000,  // log 1 message out of every 1,000.
     'level' => \Psr\Log\LogLevel::WARNING,
 $wgDebugLogGroups['redis'] = array(
     'destination' => '/var/log/mediawiki/redis.log',
     // Level can also be the literal string value of any Psr\Log\LogLevel constant
     'level' => 'info',
