Many of us have usage metrics baked into our products to gain a better understanding of how our product is being used, and to be able to optimize our products based on this data. But sometimes this isn't enough. Many times we have premium customers, with production-grade SLAs, and being able to correlate usage with specific clients, would enable us to provide a better experience for these users.

This talk will demo how we used a serverless function to manipulate our setup file to attach a unique identifier to each usage metric, so we can optimize our customers' experience, and improve our quality of service.
