OpenTelemetry Events vs. New Relic Custom Events: Capabilities, Context, and the “Why”

This article explains the difference between OpenTelemetry (OTel) Events and New Relic Custom Events, both used for observability signals. OTel Events are structured logs tied to traces for detailed debugging and root cause analysis, offering vendor neutrality. New Relic Custom Events are designed for analytics, powering dashboards, alerts, and AI model evaluation with fast, queryable data.

Essentially, OTel Events help engineers understand why something happened, while New Relic Custom Events help product and AI teams understand what is happening and proactively improve systems – and both can be used together for a comprehensive observability strategy. The article emphasizes choosing the right event type based on whether the priority is detailed diagnostics or aggregate insights.
