The blog post by Dan Gomez Blanco, a Principal Observability Architect at New Relic, explores the complexities and importance of good telemetry in observability, emphasizing that it is a crucial aspect of understanding system performance in real-time. He introduces the "Instrumentation Score," a new open standard aimed at measuring how well applications are set up for observability by considering various signals like traces, metrics, and logs. The initiative, involving collaboration from engineers at New Relic and other organizations, seeks to establish standard measurements to enhance observability practices. The article discusses how different signals serve distinct purposes and highlights the significance of using the right data to troubleshoot and monitor performance effectively. By leveraging OpenTelemetry and employing smart sampling techniques, the Instrumentation Score aims to provide a comprehensive understanding of systems while avoiding excessive costs and operational challenges. The article encourages participation in developing this standard and emphasizes that observability maturity is a gradual process requiring strategic actions to improve system insights and drive business outcomes.
