OpenTelemetry's metrics capabilities have been stabilized and are now available as release candidates, marking an important milestone in the project's evolution. The OpenTelemetry community has made significant progress in recent times, introducing new practices to build modern observability solutions. However, adopting OpenTelemetry at scale can be daunting due to its relatively new status and evolving nature. To support your organization's OpenTelemetry initiatives, it is essential to understand the current state of core components, evaluate language client SDKs for maturity, and consider limitations such as manual instrumentation and sampling methodologies. The New Relic platform provides a suitable backend for OpenTelemetry, offering flexibility, breadth, pricing control, compliance, and contributions to the OpenTelemetry project. Building a solid plan for adopting OpenTelemetry involves focusing on observability goals, developing project objectives with key stakeholders, and understanding current limitations while leveraging mixed instrumentation capabilities.
