Beyond Sequential: A Recipe for Async Pipeline Observability and Alerting

While implementing observability for thousands of microservices, we faced challenges with asynchronous pipelines that weren't covered by traditional API-based SLO approaches. This talk presents our company's journey in implementing SLOs for async systems: identifying key customer experience KPIs, leveraging Prometheus, defining good/valid events, and establishing burn rate alert thresholds. We'll share real case studies demonstrating the impact, including how we detected and resolved pipeline latency issues that affected thousands of events, along with best practices and lessons learned
