Salesforce handles billions of transactions daily, generating over 50 trillion spans. These transactions represent a complex ecosystem. Failure of even a single transaction, can leave users frustrated while everything appears “green” in the system. Why? Sampling-based tracing often misses such edge cases.
In this talk, we unveil how SF overcame this challenge by enabling 100% sampling for critical flows, all while keeping costs low. We’ll share our groundbreaking migration from Zipkin to OTel and the lessons learned along the way
Discover how we equipped SF developers with a 360-degree view of service and API performance. With OTel, they can now pinpoint RED metrics, diagnose issues faster, and achieve visibility beyond the limits of logs and metrics
We’ll also dive into the backend challenges of scaling OTel, from managing high data volumes to optimizing storage and query performance. We’ll share the pros and cons of various approaches, and our experiences with open-source tools
