Get insights into method call stats in production. Deforest tracks all your model method calls in production and presents method usage data segmented as most used (red), medium used (yellow) and least used (green).
This extension is supposed to be used in conjunction with the deforest ruby gem. Download extension data (deforest.json) file from the deforest engine and put it in the root of your rails application. Then goto the file you want to view the stats for and press (cmd + shift + p). Select "Deforest" from the command pallete and scroll up and down to see method names highlighted in (red|yellow|green).
Install the rubygem "deforest" and follow the instructions in the github page.
