Webgrind

Webgrind is an Xdebug profiling web frontend in PHP. It implements a subset of the features of kcachegrind and installs in seconds and works on all platforms. For quick'n'dirty optimizations it does the job. Here's a screenshot showing the output from profiling:

Features

  • Super simple, cross platform installation - obviously :)
  • Track time spent in functions by self cost or inclusive cost. Inclusive cost is time inside function + calls to other functions.
  • See if time is spent in internal or user functions.
  • See where any function was called from and which functions it calls.
  • Generate a call graph using gprof2dot.py

Suggestions for improvements and new features are more than welcome - this is just a start.

Installation

  1. Download webgrind
  2. Unzip package to favourite path accessible by webserver.
  3. Load webgrind in browser and start profiling

Alternatively, on PHP 5.4+ run the application using the PHP built-in server with the command composer serve or php -S 0.0.0.0:8080 index.php if you are not using Composer.

For faster preprocessing, give write access to the bin subdirectory, or compile manually:

  • Linux / Mac OS X: execute make in the unzipped folder (requires GCC or Clang.)
  • Windows: execute nmake -f NMakeFile in the unzipped folder (requires Visual Studio 2015 or higher.)

See the Installation Wiki page for more.

Use with Docker

Instead of uploading webgrind to a web server or starting a local one, you can use the official Docker image to quickly inspect existing xDebug profiling files. To use the Docker image, run the following command with /path/to/xdebug/files replaced by the actual path of your profiling files.

docker run --rm -v /path/to/xdebug/files:/tmp -p 80:80 jokkedk/webgrind:latest

Now open http://localhost in your browser. After using webgrind you can stop the Docker container by pressing CTRL / Strg + C.

To use the built-in file viewer, mount the appropriate files under /host in the container.
