The document summarizes PHP profiling software called Blackfire.io which consists of 5 components: a Probe, Agent, Client, Companion, and Website. The Probe collects performance profiles, the Agent aggregates and forwards profiles, the Client triggers profiling, and the Companion is a browser extension. It works on Linux, MacOS, with PHP 5.3+ and the Companion is for Chrome. Installation involves installing the Agent and Probe and configuring the Client. Profiling can be run from the command line or browser extension to analyze a script's performance graph on the Blackfire website.

REQUIREMENTS

4. https://blackfire.io/getting-started#installation

https://blackfire.io/account/credentials#server

INSTALLATION

5. You can run it via a convenient chrome extension or the command line.
(I did not have enough time to figure out how to get it working with a vagrant box setup but the
chrome extension would work like magic with a native dev environment)
In my case I am using the command line tool, you can run it like this:
blackfire --slot=7 --samples=10 run ./my-script.php --your-script-options and arguments
Output:
Profiling: [########################################] 10/10
