A Silverstripe module for facilitating profiling with XHProf
A Silverstripe module for facilitating profiling with XHProf.
Since the Silverstripe 3 release, Silverstripe's built-in profiling has been disabled (see this thread). Thus, this module has sprung out of neccesity for profiling in Silverstripe 3.
This is a fork from the XHProf PHP compiler, open sourced by Facebook in 2009. It has been amended for easy integration with Silverstripe as well as installation instructions in this readme.
XHProf needs to be installed and running on your system for this module to work. Once XHPprof has been installed, follow the following steps:
/framework/main.php, adding the following lines at the very top (under
<?php), and at the very bottom:
Profiler outputlink on the very bottom of your site
On an *nix machine with PECL installed, follow this instruction:
[sudo] pecl config-set preferred_state beta
[sudo ] pecl install xhprof
[xhprof] extension=xhprof.so xhprof.output_dir="/var/tmp/xhprof"`
You might need to create the dirctory
apt-get install graphviz
Beyond XHProf another PHP profiling solution would be using xDebug, combined with a visualizer, which would either be built-in to an IDE, or using the PHP-based Webgrind web interface.
