What Happened and Why: Correlating Load Testing with Observability

About this talk

Load testing tells you what happened. Observability tells you why. But too often these disciplines operate independently, leaving teams manually piecing together performance regressions with server-side telemetry after the fact. In this joint session at SREday Barcelona 2026 Q2, co-presented with Heather Thacker (Gatling), we explore how to bridge the gap — wiring load test results directly into observability pipelines so SREs and performance engineers can move from a failed test to a root-cause story without bouncing between tools.

Key takeaways

• Why load testing and observability deliver more value together than apart
• How to correlate Gatling load test metrics with Dynatrace traces, logs, and metrics
• Patterns for automating the path from a failed test to an actionable alert
• A live demo: from triggering a regression to a Slack notification with the root cause attached
