Context

• Large dashboards are a common source of performance issues in Looker. Our public documentation recommends to avoid creating dashboards with more than 25 tiles, however, there's no clear way for administrators to enforce this. Providing an automated way for administrators to notify users their dashboards don't adhere to best practices will reduce manual toil and mitigate a large contributor to performance issues.

Problem

• Getting users to adhere to dashboard best practices is a difficult and manual process.
• There's no framework or recommended method for enforcing dashboards should have less than 25 tiles.

Proposal

• An example that shows how to use the Looker API to add warning text tiles to the top of large dashboards (default is greater than 25 queries but that can be modified).
