Xdebug Profiling¶
Although DDEV has more sophisticated profiling capabilities with xhprof and blackfire.io it also has built-in support for xdebug profiling.
Basic usage¶
- Create the directory
.ddev/xdebug
, which is where the output files will be dumped. - Switch XDebug to profiling mode by adding this in
.ddev/php/xdebug.ini
xdebug.mode=profile
xdebug.start_with_request=yes
xdebug.output_dir=/var/www/html/.ddev/xdebug
xdebug.profiler_output_name=trace.%c%p%r%u.out
- Enable xdebug with
ddev xdebug on
- Do a HTTP request to the DDEV project and the profile will be located in
.ddev/xdebug
directory. - Analyze it with any call graph viewer, for example kcachegrind.
- When you're done, execute
ddev xdebug off
to avoid generating unneeded profile files.
