The basic configuration consists of loading the plugin and pointing where the xhprof_lib directory is located on your system.

On your Config/bootstrap.php file:

Options:

• library: Path to your xhprof_lib directory (required)
• namespace: Namespace to save your xhprof runs, default is your application directory name
• flags: Flags passed over to profiler, default is 0. For a list of flags visit: http://php.net/xhprof.constants.php
• ignored_functions: Array of functions to ignore, default is call_user_func and call_user_func_array
• replaceRunId: Placeholder used to replace the run id in order to display a link in the page, set false to disable, default is %XHProfRunId%. Read the usage for more information

All options example:

Usage

Dispatcher Filter

Just include the XHProfDispatcher in your dispatcher filters list on Config/bootstrap.php:

By default it will try to replace %XHProfRunId% with the saved run id from the page's output. It allows you to include a link to the xhprof report on the page.

On your View/Layouts/default.ctp:

DebugKit Panel

If you are using DebugKit, you can use the provided panel here.

Make sure you include html config of the URL endpoint of the xhprof_html folder:

Then you can add the panel in your DebugKit components setup:

Done. It should now display the new panel with the link to the result of this page output.

Manual

This method is very useful when profiling specific points on your code. For that, just use the XHProf class to assist you.

Example:

Note: There are two ways to stop the profiler as explained above. However only one can be used at each run.
