Distributed systems often feel like a black box we know something is happening inside, but we can’t see where time is being spent or what’s going wrong. This session turns that black box into a glass box by showing developers how to implement tracing with New Relic segments. You’ll learn how to instrument applications effectively, gain visibility into downstream calls, and make sense of performance bottlenecks. Whether you’re new to observability or looking to deepen your tracing practices, this talk will provide practical steps and examples you can apply immediately in your services.
