Agent Tracing
An AgentTrace is returned when calling agent.run or agent.run_async.
any-agent generates standardized (regarding the structure) OpenTelemetry traces regardless of the framework used, based on the Semantic conventions for generative AI systems. This means that any OpenTelemetry exporter compatible with the Python SDK can be added. More information can be found below.
You can try to 🔍 find 🔍 the subtle differences (regarding the content) across frameworks in the examples below.
Tip
The following are real traces generated by executing one of our integration tests.
Console
Here is what the console output looks like:

Adding an OpenTelemetry exporter
Before starting to use the library, you can add new OpenTelemetry exporters and processors as needed. Note that this does not affect the existing processor that returns the traces to the user, and optionally prints them on stdout.
The following code will use the OpenTelemetry Python SDK to send the agent traces to an additional endpoint using OTLP over HTTP in the indicated URL:
from opentelemetry.trace import get_tracer_provider
from opentelemetry.sdk.trace.export import SimpleSpanProcessor
from opentelemetry.exporter.otlp.proto.http.trace_exporter import OTLPSpanExporter
tp = get_tracer_provider()
http_exporter = OTLPSpanExporter(endpoint="http://localhost:4318/v1/traces")
tp.add_span_processor(SimpleSpanProcessor(http_exporter))
