This is a graphical front end designed to store and present the profiling information provided by the Facebook created XHProf profiling tool.

Related Tools:

  • XHGui - Uses MongoDB as a backend (rather than MySQL)
  • - Uses MySQL backend, more normalized storage schema

This branch/clone/whatever git calls it of the official Facebook GUI does a few things:

  • It includes a header.php document you can use with PHP's auto_prepend_file directive. It sets up profiling by initilizing a few variables, and settting register_shutdown_function with the footer. Once started profiles are done when requested (?_profile=1), or randomly. Profiled pages display a link to their profile results at the bottom of the page (this can be disabled on a blacklist based for specific documents. e.g. pages generating XML, images, etc.).
  • For tips on including header.php on an nginx + php-fpm install take a look at:
  • The GUI is a bit prettier (Thanks to Graham Slater)
  • It uses a MySQL backend, the database schema is stored in xhprof_runs.php
  • There's a frontend to view different runs, compare runs to the same url, etc.

Key features include:

  • Listing 25, 50 most recent runs
  • Display most expensive (cpu), longest running, or highest memory usage runs for the day
  • It introduces the concept of "Similar" URLs. Consider:
  • Highcharts is used to graph stats over requests for an easy heads up display.


Work that we're still doing:

  • The aggregation functionality is ignored completely
  • The code is... a mess. Deadlines do that to you, we're working on it
  • The default table schema isn't indexed all the places it needs to be
  • Easier ways to diff URLs
