The OpenTelemetry project aims to provide backwards compatibility with the OpenTracing project in order to ease migration of instrumented codebases. OpenTracing does not provide an API for metric collection out of the box, though there is a project that utilizes the API’s specification to collect application metrics (e.g., duration) within the context of a span. The example application is built using Spring Boot. OpenTracing Java Examples Start tracing system Spring Boot JAX-RS (Wilfly Swarm) For example a component may have security settings, credentials for authentication, urls for network connection and so forth. therefore, a new opentracing contrib project has been established (initially just for java) to intercept the finished spans, and create the relevant metrics.
