Python: Dependency on Azure Monitor OpenTelemetry package means OTEL autoinstrumentation requires Azure Monitor #1376
Description
The agent-framework package OTEL setup means that it requires Azure Monitor connection strings to be set in the environment variables or settings.
I'm trying to use the Python app with the Aspire dashboard, which uses the OTLP exporter to a local endpoint. I use OTEL auto-instrumentation to pickup the OTLP environment variables that Aspire sets, but it's colliding with Azure Monitor.
This is a reproducible sample:
from opentelemetry.instrumentation.auto_instrumentation import initialize
initialize()
...
def main():
"""Launch the spam detection workflow in DevUI."""
from agent_framework.devui import serve
port = os.environ.get("PORT", 8090)
# Launch server with the workflow
serve(entities=[workflow], port=int(port), auto_open=True)
if __name__ == "__main__":
main()I'm not using Azure Monitor in this application, my pyproject.toml is:
[project]
name = "agent-framework-demo"
version = "0.1.0"
description = "FastAPI project"
readme = "README.md"
requires-python = ">=3.13"
dependencies = [
"agent-framework==1.0.0b251007",
"azure-ai-agents==1.2.0b5",
"opentelemetry-instrumentation-fastapi",
"opentelemetry-exporter-otlp",
"opentelemetry-distro",
]OTEL fails to initialize:
