詳細

This setting is used to configure profiling of your MediaWiki installation.

利用できるキーは Manual:プロファイリング を参照してください。 They include:

'class'
E.g. ProfilerXhprof provides an Xhprof-backed profiler. There is also ProfilerExcimer which works with Excimer .
'output'
Define one or multiple output methods. For multiple output methods at the same time, use an array of class names, one for each output type you want the profiler to generate. For example use the "ProfilerOutputText" profiler. 既定であなたが利用できる出力クラスは以下の通りです: ProfilerOutputDump, ProfilerOutputStats, ProfilerOutputText.
  • ProfilerOutputStats outputs profiling data as StatsD metrics.

It expects that you have set the $wgStatsdServer configuration variable to the host (or host:port) of your statsd server.

  • ProfilerOutputText will output profiling data in the page body as a comment.

You can make the profiling data in HTML render as part of the page content by setting the 'visible' configuration flag: $wgProfiler['visible'] = true;

  • ProfilerOutputDump expects a $wgProfiler['outputDir'] telling it where to write dump files.

The files produced are compatible with the XHProf gui.

'visible'
true または false If true, output is displayed in HTML rendering (and not only in a comment).
'sampling'
正の整数。 Profile every nth request.

For performance, the profiler is always disabled for CLI scripts as they could be long running and the data would accumulate. Use the '--profiler' parameter of maintenance scripts to override this.

For a rudimentary debug profiler:

$wgProfiler= [
  'class' => 'ProfilerXhprof',
  'output' => 'text',
];
