A great question, many organisations struggle with establishing where their gates have been deployed. Fortunately, Formulayt has included a feature that will help you out.
First you will need to go to the gate activity report found on the left hand side menu.
Then search and select the gate in question.
Scroll on down past the reporting and at the bottom of the page under the world map, you will find a list of URLs where this gate has been loaded.
So there you have it, simple but effective.
You can export activity by date and URL.
If you are still having issues, fear not, Formualyt is on hand, simply click "+ New Support Ticket" above.
