Dynatrace PurePath 4 enhances observability in microservice architectures by seamlessly integrating OpenTracing data from auto- and custom-instrumented Java source code, addressing the visibility gaps often found in heterogeneous cloud-native environments. This integration, supported by Dynatrace OneAgent, enriches trace data with additional information, such as method hotspots and CPU analysis, providing a comprehensive end-to-end view of transactions, even in hybrid deployments. The collaboration with the OpenTelemetry community ensures that Dynatrace can ingest custom metrics and offer robust analytics, including service hotspot analysis and always-on profiling, without manual configuration. These capabilities are especially beneficial for complex architectures that rely on third-party libraries, like Hazelcast, to handle high traffic scenarios, improving the user experience and enabling rapid problem resolution. Dynatrace encourages feedback from users and offers a free trial for new customers to experience these advanced observability features, while also announcing upcoming enhancements in OpenTracing and OpenTelemetry capabilities.
