===Install Xdebug with php-fpm per pool===

Ever need to install xdebug to create cachegrind files for only specific php-fpm pool

==Install Xdebug==

Fastest way to install xdebug

 pecl install xdebug

Or if you're using SCL with multiple version

 scl enable <phpverson> 'pecl install xdebug'

==Configure xdebug.ini==

We only want specific php-fpm pools to create cachegrind files

 zend_extension="/usr/lib64/php/modules/xdebug.so"
 xdebug.profiler_enable = 0
 xdebug.profiler_output_name = "cachegrind.out.%H.%p"
 xdebug.profiler_enable_trigger = 0

You might have to change the zend_extension location to match your location

==Configure php-fpm pool ==

Add the following to your php-fpm pool config:

 php_admin_flag[xdebug.profiler_enable_trigger] = On
 php_admin_value[xdebug.profiler_output_dir] = /home/<user>/xdebug
 php_admin_flag[xdebug.remote_enable] = On;

Again you can change the output location by changing the  php_admin_value[xdebug.profiler_output_dir]  

Then make the output directory:

 mkdir /home/<user>/xdebug

==Create cachegrind files==

Then use the following flag to create the cachegrind file

http: / /<domain>/?XDEBUG_PROFILE=1 or any page with ?XDEBUG_PROFILE=1
