Overview
Complete API reference documentation for thefiddler-adk package, which
instruments Google ADK (Agent Development Kit)
and exports OpenTelemetry traces to Fiddler.
The package is published to PyPI as fiddler-adk and imported in
Python as fiddler_adk:
Components
Instrumentation
GoogleADKInstrumentor sets up the Fiddler tracing pipeline and promotes it
to the global tracer provider so ADK’s gcp.vertex.agent tracer resolves to it.
Span Processor
ADKSpanProcessor backfills gen_ai.conversation.id from child spans onto
the root invocation span, ensuring all spans in a turn share the same session
identity in the Fiddler UI.
