[tracing] Create and reparent span for Azure API Management by jcstorms1 · Pull Request #7806 · DataDog/dd-trace-dotnet

jcstorms1 · 2025-11-12T19:46:47Z

Summary of changes

New logic to identify Azure API Management headers
Correctly creates an APIM span and reparents it as the parent for Isolated HTTP Azure Functions
Refactored existing AWS proxy logic and tests to account for the addition of the Azure Proxy.
Changes inferred proxy span.kind to server instead of internal to follow this spec

Note: This PR does not include functions using ASP.NET Core and will be added later

Reason for change

This is a frequently requested feature for proper distributed tracing with Azure Functions using APIM

APMSVLS-245

Comparison explanation

Execution-time benchmarks measure the whole time it takes to execute a program, and are intended to measure the one-off costs. Cases where the execution time results for the PR are worse than latest master results are highlighted in **red**. The following thresholds were used for comparing the execution times:

Welch test with statistical test for significance of 5%
Only results indicating a difference greater than 5% and 5 ms are considered.

Note that these results are based on a single point-in-time result for each branch. For full results, see the dashboard.

Graphs show the p99 interval based on the mean and StdDev of the test run, as well as the mean value of the run (shown as a diamond below the graph).
