Query Monitor Flamegraph This Query Monitor extension will add profiling framegraphs to Query Monitor via the xhprof PHP extension.
A Human Made project. Maintained by @joehoyle.

Install Instructions

1. Have the Query Monitor plugin installed and activated.
2. Have the xhprof PHP extension installed.
3. Install this plugin :)
4. Add a call to xhprof_sample_enable(); to your wp-config.php

Versions of XHProf

Unfortunately XHProf is not actively maintained and has some shortcomings. Flamegraph makes use of the xhprof_sample_enable() function which by is hardcoded to 100ms intervals with the official XHProf extension. There's several forks and updates to XHProf, refer to the table below:

|Project|Compatible|Notes| |—|—|—| |XHProf Official|yes|Note: Doesn't support PHP 7. Is restricted to 100ms interval sampling, making it useless for the most part.| |XHProf with configurable sampling|yes|Note: Doesn't support PHP 7. Best solution! However, you'll need to build from source.| |Tideways|no|Tideways is an XHProf fork, however doesn't support *_sample_enabled. See https://github.com/tideways/php-profiler-extension/issues/26.| |XHProf PHP7 fork|no|Doesn't support xhprof_sample_enabled|

If you know of any other XHProf forks or compatible output libraries, be sure to let me know!
