Manual:$wgDebugLogGroups

デバッグ: $wgDebugLogGroups
特定のグループの wfDebugLog() の出力先を $wgDebugLogFile 以外のファイルに変更する。
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
許容される値:	(記録グループ キーからファイル名への連想配列)
既定値:	[]
その他の設定: アルファベット順 | 機能順

詳細

記録グループ キーからファイル名への連想配列を設定します。 If set, wfDebugLog() output for that group will go to that file instead of the regular $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 log level (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.

例

この例では、グループ「ConfirmEditExtension」のデバッグ メッセージは「debug-ext_confirmedit.log」に、「SpamRegex」のデバッグ メッセージは「debug-spam.log」に、それぞれ出力されます。

$wgDebugLogGroups = [
	'ConfirmEditExtension'	=> $IP . '/../../home/debug-ext_confirmedit.log',
	'SpamRegex'		=> $IP . '/../../home/debug-spam.log',
];

例:

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

高度な例:

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

Multiple log groups in a single file

You might want to setup a temporary configuration like the following to see all authentication related logging to trouble-shoot authentication.

$wgDebugLogGroups['cookie'] =
	$wgDebugLogGroups['session'] =
	$wgDebugLogGroups['SimpleSAMLphp'] =
	$wgDebugLogGroups['PluggableAuth'] = "$IP/cache/PluggableAuth.log";

Some common debug log groups

• exception, error, fatal - errors
• deprecated - deprecation warnings
• objectcache, caches, memcached/SQLBagOStuff - キャッシュ
• rdbms - database (including, if $wgDebugDumpSql is set, all DB queries)
• cookie - response cookies
• exec - shell commands
• session - SessionManager
• authentication, login - AuthManager
• ratelimit, throttler - hitting rate limits ($wgRateLimits and other)
• resourceloader, ResourceLoaderImage - ResourceLoader
• http, HttpError - HTTP requests to external services (via the Http/MwHttpRequest classes)
• api - API
• thumbnail, fileupload, fileconcatenate - image-related
• runJobs - ジョブ キュー
• parser, ParserCache - パーサー
• slow-parse - warnings about pages that take long to parse
