How to monitor spring boot micrometer metrics

Daniel Fitzgerald from New Relic highlights how open-source monitoring, particularly using Micrometer with Spring Boot, can integrate telemetry data into New Relic One to prevent data silos and enhance service monitoring. The New Relic Micrometer registry allows applications to send metrics to New Relic, offering a powerful and flexible way to collect, expose, and analyze metrics such as counters, gauges, timers, and distribution summaries. It supports the differentiation between tracing and metrics, where tracing provides a detailed view of request flows and metrics offer quantitative insights into performance over time. The blog further explains the setup and benefits of using the New Relic Micrometer registry through a demo involving the Spring Pet Clinic Microservices, emphasizing best practices in monitoring, such as defining clear goals, using meter filters, and integrating with time-series databases like Prometheus. The post also discusses leveraging distributed tracing and the importance of adapting monitoring strategies as applications evolve, alongside New Relic's efforts in open instrumentation initiatives like OpenTelemetry to enhance telemetry data usability.
