Cephalon.Observability.NewRelic adds New Relic native OTLP endpoint defaults for Cephalon hosts.
What it owns
Section titled “What it owns”- host-builder registration for OTLP logs, metrics, and traces over the shared
Engine:Observability:Telemetrycontract when a shared collector endpoint is already in place - an opt-in New Relic native OTLP path that can derive the documented regional endpoints or use an explicit OTLP endpoint override
api-keyheader guidance from either raw OTLP headers or a structured New Relic license-key setting- startup diagnostics that summarize the active New Relic export mode without logging secrets

How it fits
Section titled “How it fits”This package stays outside Cephalon.Engine and Cephalon.Observability on purpose. The engine still owns diagnostics names and lifecycle signals, Cephalon.Observability still owns the shared telemetry contract, and this companion package layers New Relic-specific OTLP endpoint and api-key authentication guidance on top of the same OTLP baseline.
The New Relic slice is intentionally explicit about its two modes. If a host already has a shared OTLP collector or gateway path, the package keeps using the shared Endpoint or UseSelfHostedDefaults flow and only adds explicit resource context such as service.namespace and deployment.environment.name. If the host wants New Relic native OTLP ingestion instead, it can enable Engine:Observability:Telemetry:NewRelic:UseNativeOtlpEndpoint, keep the provider on OpenTelemetry, and configure either the raw OTLP Headers value or a structured LicenseKey that the package converts into the required api-key header. If Endpoint is omitted in that direct mode, the package derives the documented OTLP base endpoint from the configured Region.
