In the context of complex and expanding distributed systems, observability has become crucial for maintaining the health of IT infrastructure and digital platforms. While monitoring provides insights into known issues by tracking metrics, events, logs, and traces, observability goes further by identifying why issues occur, including unknown factors, through tools like Open Telemetry. Open Telemetry is an open-source framework hosted by the Cloud Native Compute Foundation that focuses on generating, collecting, and exporting telemetry data, supporting a wide variety of tech stacks without vendor lock-in. Its primary role is to facilitate the integration of telemetry signals such as metrics and traces into observability solutions, though it does not act as a backend for storage or visualization itself. With its extensible nature, Open Telemetry allows for customizations and collaborations, enhancing the ability to make data-driven decisions. New Relic, a key contributor to Open Telemetry, offers robust support and integration, enabling enterprises to achieve comprehensive observability and proactive monitoring.
