Distributed traces provide crucial insights into the end-to-end execution paths of application requests, aiding developers and architects in ensuring their code interacts correctly with various service versions. By integrating observability platforms with development tools, engineers can easily analyze these traces during testing to verify backend service calls and other critical interactions. In environments with numerous microservices, capturing millions of traces demands automated analysis to address questions related to service versions and their impacts on system performance. Dynatrace’s PurePath technology automates this process by capturing version information and offering real-time analysis, which is essential for DevOps and SRE teams to make informed decisions about service deployments and updates. Through examples and demos, Dynatrace demonstrates the ability to detect issues such as regressions and anomalies across different service versions, emphasizing the need for automated tools to handle the vast amounts of data generated by modern distributed systems. This capability not only aids in improving release decisions but also highlights the value of using Dynatrace's automated solutions for efficient and accurate system monitoring.
