High Resolution Performance Telemetry at Scale

One of the most critical aspects of running large distributed systems is understanding and quantifying performance. Without telemetry it is challenging to diagnose performance issues, plan for capacity needs, and tune for maximum efficiency. Even when we have telemetry, the resolution is insufficient to capture anomalies and bursty behaviors that are typical in microservice architectures.

In this talk, we explore the issues of resolution in performance monitoring, cover sources of performance telemetry including hardware performance and eBPF, and learn some tricks for getting high resolution telemetry without high costs.
