OpenLLMetry

OpenLLMetry instruments the model client a framework calls, so it records frameworks that emit no GenAI spans of their own. Python.

Turn tracing on

pip install traceloop-sdk

Once at startup, before the framework is imported:

import os

os.environ["TRACELOOP_TRACE_CONTENT"] = "false"
os.environ["TRACELOOP_TELEMETRY"] = "false"
os.environ["TRACELOOP_METRICS_ENABLED"] = "false"

from traceloop.sdk import Traceloop

Traceloop.init(
    app_name="research-agent",
    api_endpoint="https://<gateway>",
    headers={
        "X-Api-Key": "organisations/<organisation>/apiKeys/<key>",
        "X-Api-Secret": os.environ["AGENTPULSE_SECRET"],
        "X-Agentpulse-Agent": "organisations/<organisation>/agents/<agent>",
    },
)

api_endpoint is the gateway alone; /v1/traces is added for you. The three settings keep prompts off the spans and stop it sending metrics and usage data of its own.

What is recorded

  • Each OpenAI client call, with its model, provider and tokens, cached tokens included.
  • A call that fails, as failed, with the client's error name.
  • Not tool calls: OpenLLMetry has no tool span.

A streamed OpenAI call reports tokens only when the request asks for them with stream_options={"include_usage": True}. Without it the call is not recorded.

Checked with traceloop-sdk 0.62 on the OpenAI client, CrewAI, LlamaIndex, Haystack and AutoGen.

Budgets

Spans arrive after the call, so spend counts against your budgets and raises alerts, but a budget cannot stop a call recorded this way.
