![]() ![]() ![]() If you do decide to go with XHProf take a look at XHGUI. htaccess file in the appropriate directory, periodically, and then move it out of the directory. Example: configconfig FALSE configqueries. gcstats Enables Garbage Collection Statistics to collect statistics about PHPs Garbage Collection Mechanism. First, you can set application wide defaults with the application/config/profiler.php config file. This can be used to step through your code while it is running, and analyse values of variables. The only option I could see that would profile a relatively random sample of requests is to have a cron script place an. Enables Code Coverage Analysis to generate code coverage reports, mainly in combination with PHPUnit. This means that should someone mischievous want to, they could slow your server to a crawl by simply appending that GET parameter to a bunch of requests. There are a multitude of profilers available for WordPress but they all fail in some way to provide the real results you need. In the latter case you must have an XDEBUG_PROFILE GET or POST parameter set or send a cookie with the name XDEBUG_PROFILE. htaccess file via xdebug.profiler_enable = 1 or selectively turning on profiling via xdebug.profiler_enable_trigger = 1. The injected code adds a GUID to each unique transaction to the application, and performs. Your options for enabling profiling within xdebug are limited to either having profiling always on via a php.ini file or. The profiler then injects a code into the PHP application code. XHProf Profiler is definitely the best tool for the job when it comes to profiling code within a production environment. Xdebug is a standard PHP profiler that you can use to discover a variety of performance issues in your scripts. What's the best way to trigger the profiler for an appropriate sample size?Īny other insight into the matter would be much appreciated.ĭon't reinvent the wheel.Does installing xdebug on production open the server up to attackers/exploiters in any way (assuming the debugger is not enabled)? Is there a boiler-plate config for this type of setup?.Profilers can answer questions like, How many times is each method in my code called and, How long do each of these methods take Profilers also track things like memory allocations and garbage collection. Is this kind of feature even advisable? I'd like to get some real world data from the production environment but not if it means destroying the user experience due to overhead. Typically code profilers are used by developers to help identify performance problems without having to touch their code.So my questions are (assuming xdebug is the profiler): ![]() I know there is a way to achieve such a task with Facebook's XHProf Profiler but was hoping for a similar solution using xdebug. Something like 1 profile per every 10,000 requests. Obviously it's a bad idea to profile ALL requests because of the added overhead so I was looking into some techniques that will randomly invoke the profiler per request. I'm toying around with the idea of implementing something that profiles code on the production server and wanted some best-practice advice. ![]()
