Which tool is required to create server-side PurePaths?

Creating server-side PurePaths requires the Dynatrace OneAgent SDK. This tool is specifically designed to enable developers to instrument their applications for comprehensive monitoring and tracing of transactions within a server environment. The OneAgent SDK provides capabilities to embed tracing code directly into server-side logic, which helps in capturing detailed performance metrics and transaction flows.

By employing the OneAgent SDK, developers can define custom entry points, capture specific events, and measure the performance of various components within the application. This level of instrumentation is essential for achieving high-fidelity PurePaths, which display a complete view of the end-to-end transaction journey, including the time spent in different components and services.

While other tools mentioned have their specific use cases, they don't serve the same purpose for creating server-side PurePaths. Dynatrace OpenKit is typically used for instrumenting client-side applications, Dynatrace AppMon relates to older architectures and does not support the latest dynamic environments like the OneAgent SDK, and Dynatrace Custom Agent, while useful for specialized scenarios, does not provide the same ease of integration and broad capabilities as the OneAgent SDK for server-side PurePath creation.
