Live Profiler UI
================

![logo](https://raw.githubusercontent.com/badoo/liveprof-ui/master/images/liveprofui_logo.png "logo")

[Live profiler](https://github.com/badoo/liveprof) is a system-wide performance monitoring system in use at Badoo that is built on top of [XHProf](http://pecl.php.net/package/xhprof) or its forks ([Uprofiler](https://github.com/FriendsOfPHP/uprofiler) or [Tideways](https://github.com/tideways/php-profiler-extension)).
Live Profiler continually gathers function-level profiler data from production tier by running a sample of page requests under XHProf.

Live profiler UI aggregates the profile data corresponding to individual requests by various dimensions such a time, memory usage, and can help answer a variety of questions such as:
What is the function-level profile for a specific page?
How expensive is function "foo" across all pages, or on a specific page?
What functions regressed most in the last day/week/month?
What is the historical trend for execution time of a page/function? and so on.

You can find the full documentation in [Live Profiler UI wiki](https://github.com/badoo/liveprof-ui/wiki)

Here is [a plugin](https://plugins.jetbrains.com/plugin/13767-live-profiler) for PhpStorm to see the method performance directly in IDE.

System Requirements
===================

* PHP version 7.3 or later to use web interface and run aggregation scripts. 
* PHP version 5.4 or later / hhvm version 3.25.0 or later to collect profiles using [Live Profiler](https://github.com/badoo/liveprof)
* Connection to database with profiling result. You can collect profiles using [Live Profiler](https://github.com/badoo/liveprof) tool
* Database extension (mysqli, pgsql, sqlite support included)
* Perl for flame graph functionality

Key features
============

* Get stats of average value, minimum, maximum, 95 percentile of execution time, cpu time, memory usage and calls count. 
  Parameter list and statistics functions are configurable.
* Graphs for every collected parameter and every method up to 6 months. Each graph also includes children stats. It helps to see the history of changes.   
* Differences interface to compare a particular request for two dates and see what became worse.
* See [flame graph](http://www.brendangregg.com/flamegraphs.html) of the aggregated request.
* Get list of requests where a method was called last time. It may be helpful for refactoring purposes and find unused methods.
* Get the most changed methods in any requests for two dates, for example, today and a week ago. It can help to find a place of a potential performance problem.
