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.
Info
Check the exposed attributes in GenAI
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:

Dumping to File
The AgentTrace object is a pydantic model and can be saved to disk via standard pydantic practices:
from any_agent import AgentConfig, AnyAgent
from any_agent.tools import search_web
agent = AnyAgent.create(
"openai",
agent_config=AgentConfig(
model_id="mistral/mistral-small-latest",
tools=[search_web],
)
)
agent_trace = agent.run("Which agent framework is the best?")
with open("agent_trace.json", "w", encoding="utf-8") as f:
f.write(agent_trace.model_dump_json(indent=2, serialize_as_any=True))
Tip
Passing serialize_as_any=True makes sure that the final_output gets dumped
even when AgentConfig.output_type is used.
Adding an OpenTelemetry exporter
Before starting to use the library, you can add new OpenTelemetry exporters and processors as needed.
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:
Tip
To use custom exporters you need to install their required dependencies,
In this example, it would be pip install opentelemetry-exporter-otlp.
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))
