After upgrading our .NET 8 Function applications to use Microsoft.Azure.Functions.Worker, Microsoft.Azure.Functions.Worker.Sdk, and Microsoft.Azure.Functions.Worker.Core version 2.0.0, we noticed that logs and traces from Microsoft.Extensions.Logging no longer appear in Datadog. These applications are configured to use Agentless Logging with APM.

Environment

Temporary Resolution

To restore functionality, we downgraded to the following versions of the Azure Functions Worker libraries:

  • Microsoft.Azure.Functions.Worker v1.24.0
  • Microsoft.Azure.Functions.Worker.Sdk v1.18.1
  • Microsoft.Azure.Functions.Worker.Core v1.20.0

Additional Reference

We recently reported a similar issue (#292 (comment)), which was related to .NET APIs.

Hi @licoto it looks like dd-trace-dotnet doesn't yet support V2 of Microsoft.Azure.Functions.Worker.Core which would explain why you are missing logs/traces with it.

I've created a task internally for us to add support for that new version.

@bouwkast Thank you so much for your quick answer. In this case can we leave this issue open to track progress on that support ?
