This sample shows how you can observe an agent in Agent Framework by using the
same observability setup function.
Pre-requisites:
- A Foundry project
- An observability backend to receive traces and metrics (for example, a local or remote
OpenTelemetry Collector, another OTLP-compatible backend, or console exporters enabled
via environment variables).
