Modern observability isn’t just about logs and traces; it’s about actionable signals. OpenTelemetry (OTel) Events and New Relic Custom Events are both event-driven signals - but they solve different problems. The “why” behind each is about who consumes the data and what decisions it enables.
As teams adopt AI-powered services, LLM-based pipelines, and complex distributed architectures, the volume of signals grows exponentially. Knowing which event mechanism to reach for - and when - can mean the difference between a team that reacts to incidents and one that proactively improves its systems.
Why This Matters
If your signals are only good for debugging, product and AI teams miss critical insights. If your signals are only good for analytics, engineers lose the diagnostic trail. The best teams do both:
OTel Events → precise diagnostic (log) context tied to traces
