The evolution of web development has led to increased complexity and expectations from applications to be available on multiple devices, resulting in a need for more sophisticated tooling and infrastructure, including containerization, distributed architecture, and Kubernetes. This growth in complexity also made it challenging to obtain telemetry data, leading to the creation of OpenTelemetry, an umbrella project that unified OpenTracing and OpenCensus into a single standard for metrics and traces across all application surfaces. OpenTelemetry offers a unified API for collecting and shaping metric data, reducing the need to learn unique telemetry API specifications and reformatting data for new observability providers, thereby decreasing complexity and cognitive overhead.
