Principled Performance Analytics

Wednesday, March 16, 2022 - 10:50 am–12:10 pm

Narayan Desai and Brent Bryan, Google


This talk presents an exciting analytical method that is successfully delivering high fidelity insights useful in analyzing and diagnosing distributed systems. It has been used in production in a variety of complex services at scale (up to 1.4T events/day), where traditional methods have failed, with good results. We will sketch out the problem domain in detail, present the statistical methods used, as well as the intuition behind the approach.

Attendees will gain an alternative lens through which they can analyze performance, as well as an understanding of pitfalls.
