A new tool for measuring performance in Drupal 8 - Drupal Dev Days Montpellier
2 likes1,416 views
The document introduces a Drupal 8 tool called the WebProfiler module, which leverages Symfony's profiler functionalities for performance monitoring. It provides features like data collection on rendered pages and integrates with XHProf for detailed profiling. The tool also offers command line functionalities for benchmarking and analyzing route performance within Drupal 8 installations.

Instrumented
(collect data and
store profile)
Request Response
<div id="webprofilerefa2f1"></div>
<script>
Webprofiler = (function () {
[…]
}
</script>
Response
• Add HTTP header -> X-Debug-Token: efa2f1
• Inject some javascript in the page:](https://image.slidesharecdn.com/drupaldevdays-150416104237-conversion-gate01/85/A-new-tool-for-measuring-performance-in-Drupal-8-Drupal-Dev-Days-Montpellier-12-320.jpg)
A new tool for measuring performance in Drupal 8 - Drupal Dev Days Montpellier
- 1. A new tool for measuring performance in Drupal 8 Luca Lusso
- 2. Luca Lusso • Senior Drupal Developer @ Wellnet - Italy • Acquia developer and backend developer certification • Twitter: @lussoluca • drupal.org/IRC: lussoluca • Not so fluent in english… sorry
- 3. Symfony has a great profiler tool symfony.com/doc/current/cookbook/profiler
- 4. Symfony profiler • Performance monitoring • Huge amount of high-level data about application’s internals (database query, rendered forms, errors, http request and response headers, routing, events, services, …) • Useful in functional testing (more on this later)
- 5. Drupal 8 is built on Symfony so… we have the profiler too?!
- 6. Nope…
- 7. But wait… the Symfony profiler classes are declared in the HttpKernel component, here: core/vendor/symfony/http-kernel/Symfony/ Component/HttpKernel/Profiler And the HttpKernel IS in Drupal 8, so what is missing?
- 8. Glue code is in FrameworkBundle and WebProfilerBundle But Symfony bundles doesn't works in Drupal 8 :-(
- 9. Two options: 1. make Symfony bundles works in Drupal 8 (www.drupal.org/node/1880196 -> won't fix) 2. move the bundle code to a Drupal module We choose the Drupal way™
- 11. Implemented DataCollectors PHP Config Request Timeline Frontend Database User Views Block Http Extensions Events State Config Assets Cache Routing Service Forms Every widget shows data about a metric measured by a data collector on the current rendered page
- 12. How does it work Instrumented (collect data and store profile) Request Response <div id="webprofilerefa2f1"></div> <script> Webprofiler = (function () { […] } </script> Response • Add HTTP header -> X-Debug-Token: efa2f1 • Inject some javascript in the page:
- 13. How does it work Profiling turned off Ajax Request Response /profiler/efa2f1 Returns only the toolbar DOM (with embedded javascript, css and icons)
- 14. Integration with XHProf/UProfiler Drupal 8 version of XHProf module is compatibile with Webprofiler (www.drupal.org/project/xhprof) admin/config/development/profiler/configureadmin/config/development/xhprof
- 15. Demo
- 16. What you can measure, you can optimize
- 17. Integration with Drupal Console project • Leverages the Symfony Console Component to provide a powerful CLI • Started as scaffolding generator now expose an increasing number of commands to interact with a Drupal 8 installation • Modules can contribute implementing new commands drupalconsole.com
- 18. Implemented commands • webprofiler:list -> list stored profiles • webprofiler:export -> export stored profiles • webprofiler:benchmark -> benchmark an URL running a huge number of requests and compute statistics • webprofiler:analyze -> analyze all stored profiles for a specific route and compute statistics (not yet available on drupal.org)
- 19. Benchmark an URL • Anonymous user console webprofiler:benchmark http://d8 —runs=10 • Logged-in user console webprofiler:benchmark http://admin:admin@d8/admin/ people —runs=10 • Rebuild cache before benchmark console webprofiler:benchmark http://d8 --runs=10 —cache- rebuild • Store results in a file console webprofiler:benchmark http://d8 --runs=10 --file=/Users/ lussoluca/Desktop/benchmark.yml
- 20. Analyze a route • Default front page console webprofiler:analyze view.frontpage.page_1 GET average • User profile page console webprofiler:analyze entity.user.canonical GET average
- 21. Write a new datacollector Contrib modules can provides new data collectors • find a service to instrument • write a new class to wrap/replace the original service • alter the container to instrument the service • write a new data collector class • write a new template class
- 22. Functional testing • We can mock the plugin.manager.mail service or the http_client service, for example, but if we want to write a functional test with a real integration? • Maybe we want to test how much time is spent or how much memory is consumed We can use data profiled by Webprofiler in our assertions symfony.com/doc/current/cookbook/testing/profiling.html
