Instrumenter

Command: js-instrument
Basic usage: js-instrument -o /path/to/output.js -c /path/to/inst.js input.js

Instrumenter tool takes input file with your code, instruments it with client instructions and places output to path specified by -o or --output option.

You need to include client file in your project as well to handle added instructions. To use default instrumenter client pass the option -c or --client with path where to place client's file. Note that the client script should be included before the instrumented script on the page.

When using default client it will export window.inst object. Use window.inst.result() method to see current statistics.
