Gauges Destination
When you enable Gauges in the Segment web app, your changes appear in the Segment CDN in about 45 minutes, and then Analytics.js starts asynchronously loading Gauges' track.js onto your page.
This means you should remove Gauges' snippet from your page.
Gauges starts automatically collecting data on your site.
When you call page, we call Gauges' track method with no arguments.
Gauges doesn't record data from any browser where you've signed into Gauges. That way your data doesn't get polluted by your own actions. If you want your browsing to show up in Gauges - open an incognito/private window in your browser.
Segment lets you change these destination settings from the Segment app without having to touch any code.
You can find your Site ID under Management > Tracking Code in your Gauges Dashboard. It should be 24 characters long, and look something like this: 93f0e8b9f5a1f530a7000001.
