Extension:PerformanceMonitor/pt-br

The PerformanceMonitor extension profiles the work of PHP functions and methods on your server. These "profiles" (i.e. logfiles) are stored as Json-Trees in the file system. After profiling you can use the Special Page Special:PerformanceMonitor to visualise the results as diagrams. The diagrams allow drilling down to more detailed levels and show you, whatever the server does all the time you are waiting for it.

Technically the extension uses a JavaScript library called InfoVis for visualisation, which you have to download separately and put it inside the extension folder.

Download PerformanceMonitor
The code of this extension is available for download on GitHub. Put it into the folder /extensions/PerformanceMonitor.

Download the InfoVis Toolkit
Download the InfoVis Toolkit from http://philogb.github.io/jit/downloads/Jit-2.0.1.zip and put it inside the /extensions/PerformanceMonitor/js-includes/jit-2.0.1 folder of the extension.

Download Bootstrap Library
Download the Bootstrap Library from http://getbootstrap.com/getting-started/ and put it inside the /extensions/PerformanceMonitor/js-includes/bootstrap-3.1.1-dist folder of the extension.

LocalSettings.php
use

instead of

StartProfiler.php
The file StartProfiler.php is located (if it exists) in the main folder of the wiki, i.e. the same as LocalSettings.php. If it exists, comment out the current code and add the following code. Otherwise create it and put the following inside:

ProfilerSimple.php
Descobrimos que ProfilerSimple.php foi removido em uma das últimas versões do MediaWiki, quando "a definição de perfis do Mediawiki 1.25 foi completamente reescrita" (consulte ) You can find the old file from back then (should be MW 1.20), that used to be shipped in /includes/profiler/ProfilerSimple.php - it was only used to derive a profiler from it, that creates a json file instead of the normal line-by-line protocol. Feel free to adapt this for newer versions of MediaWiki...
