Best practice for integrating OpenTelemetry-based observability (e.g. Pydantic Logfire) with Semantic Kernel?

[stefanosambruna]

Hi everyone, I’m looking into integrating third-party observability tools built on OpenTelemetry (for example Pydantic Logfire) into a project using Semantic Kernel.

To clarify upfront:
I’m not interested in Application Insights. I’m specifically looking for guidance on plugging external OpenTelemetry-compatible tools, mainly because of different requirements around UX, trace quality, and developer experience.

The goal is to achieve end-to-end observability (traces, logs, metrics) across multi-step SK workflows and agent interactions, without adding invasive instrumentation.

Any best practices, patterns, or pointers would be greatly appreciated. Thanks! 🙌
