ASP.NET Web Service observability and performance optimization face challenges as traditional monitoring tools often provide only global Service Level Indicators (SLIs) and fail to offer metrics for individual service endpoints. This limitation arises because ASP.NET SOAP Web Services (ASMX) expose endpoints through a common URL, relying on the SoapAction HTTP Header to execute specific methods, which most tools overlook. Dynatrace, with its OneAgent, traces web service requests as PurePaths, offering distributed trace capabilities and allowing deeper analysis. However, to enhance observability at the endpoint level, additional context from the SoapAction header is needed, which can be captured using Dynatrace’s Request Attributes without code changes. This approach allows for a more detailed analysis of service performance and architectural issues, enabling engineers to identify performance bottlenecks or architectural hotspots. Triscon, a partner specializing in load and performance testing, demonstrated how Request Attributes can extract context like service method names, facilitating multi-dimensional analysis and improving diagnostics. By defining custom request naming rules, Dynatrace users can achieve enhanced visibility into PurePaths, enabling effective monitoring, diagnostics, and optimization of ASP.NET Web Services.
