OpenTelemetry is an open-source framework for collecting and analyzing telemetry data like traces, metrics, and logs in Java applications. It provides powerful tools for distributed tracing, performance monitoring, and log correlation, enabling developers to gain comprehensive visibility into their applications. With pre-built libraries for popular Java frameworks like Spring Boot and JAX-RS, OpenTelemetry simplifies integration and enhances observability in complex systems. Its vendor-agnostic nature ensures compatibility with various monitoring solutions, offering flexibility and scalability. By using OpenTelemetry, Java developers can proactively identify bottlenecks, optimize performance, and improve application reliability in dynamic, distributed environments. Learn more here.
