New Relic has announced support for Spring 5, a new web framework that provides non-blocking I/O and encourages a reactive coding style ideal for high-throughput services. New Relic APM monitors Spring 5 services by identifying incoming requests and tracking activity, allowing users to identify bottlenecks and service failures. The tool also tracks cross-thread activity of WebFlux routing and WebClient external calls, providing visibility into the entire distributed system. With this instrumentation, users can trace activity from their Spring 5 service to other services using different frameworks or languages, making it easier to monitor and optimize their microservices architecture.
