How Has This Been Tested?

1. Built the deb packages and applied to my local env.
2. Then, deployed a new VM and ensured that the new option was available at the Metrics tab
3. Tested all the available intervals and validated that the updated data was fetched (or not, if None was selected) after the selected amount of time.
