tntSniff

Tired of digging through network traffic to find custom metric information buried within the payload? Then this is the extension for you. The tntSniff Dev tools panel extension listens for traffic across all browser tabs, listening for clicks (v120), seen impressions (c16), ref params (v8), pev2, and activity map values. No need to initialize it on multiple tabs, only one. Be sure to enable "Allow in Incognito" if validating metrics in incognito mode.
