feat!: Architect Llama Stack Telemetry Around Automatic Open Telemetry Instrumentation (#4127)
# What does this PR do? Fixes: https://github.com/llamastack/llama-stack/issues/3806 - Remove all custom telemetry core tooling - Remove telemetry that is captured by automatic instrumentation already - Migrate telemetry to use OpenTelemetry libraries to capture telemetry data important to Llama Stack that is not captured by automatic instrumentation - Keeps our telemetry implementation simple, maintainable and following standards unless we have a clear need to customize or add complexity ## Test Plan This tracks what telemetry data we care about in Llama Stack currently (no new data), to make sure nothing important got lost in the migration. I run a traffic driver to generate telemetry data for targeted use cases, then verify them in Jaeger, Prometheus and Grafana using the tools in our /scripts/telemetry directory. ### Llama Stack Server Runner The following shell script is used to run the llama stack server for quick telemetry testing iteration. ```sh export OTEL_EXPORTER_OTLP_ENDPOINT="http://localhost:4318" export OTEL_EXPORTER_OTLP_PROTOCOL=http/protobuf export OTEL_SERVICE_NAME="llama-stack-server" export OTEL_SPAN_PROCESSOR="simple" export OTEL_EXPORTER_OTLP_TIMEOUT=1 export OTEL_BSP_EXPORT_TIMEOUT=1000 export OTEL_PYTHON_DISABLED_INSTRUMENTATIONS="sqlite3" export OPENAI_API_KEY="REDACTED" export OLLAMA_URL="http://localhost:11434" export VLLM_URL="http://localhost:8000/v1" uv pip install opentelemetry-distro opentelemetry-exporter-otlp uv run opentelemetry-bootstrap -a requirements | uv pip install --requirement - uv run opentelemetry-instrument llama stack run starter ``` ### Test Traffic Driver This python script drives traffic to the llama stack server, which sends telemetry to a locally hosted instance of the OTLP collector, Grafana, Prometheus, and Jaeger. ```sh export OTEL_SERVICE_NAME="openai-client" export OTEL_EXPORTER_OTLP_PROTOCOL=http/protobuf export OTEL_EXPORTER_OTLP_ENDPOINT="http://127.0.0.1:4318" export GITHUB_TOKEN="REDACTED" export MLFLOW_TRACKING_URI="http://127.0.0.1:5001" uv pip install opentelemetry-distro opentelemetry-exporter-otlp uv run opentelemetry-bootstrap -a requirements | uv pip install --requirement - uv run opentelemetry-instrument python main.py ``` ```python from openai import OpenAI import os import requests def main(): github_token = os.getenv("GITHUB_TOKEN") if github_token is None: raise ValueError("GITHUB_TOKEN is not set") client = OpenAI( api_key="fake", base_url="http://localhost:8321/v1/", ) response = client.chat.completions.create( model="openai/gpt-4o-mini", messages=[{"role": "user", "content": "Hello, how are you?"}] ) print("Sync response: ", response.choices[0].message.content) streaming_response = client.chat.completions.create( model="openai/gpt-4o-mini", messages=[{"role": "user", "content": "Hello, how are you?"}], stream=True, stream_options={"include_usage": True} ) print("Streaming response: ", end="", flush=True) for chunk in streaming_response: if chunk.usage is not None: print("Usage: ", chunk.usage) if chunk.choices and chunk.choices[0].delta is not None: print(chunk.choices[0].delta.content, end="", flush=True) print() ollama_response = client.chat.completions.create( model="ollama/llama3.2:3b-instruct-fp16", messages=[{"role": "user", "content": "How are you doing today?"}] ) print("Ollama response: ", ollama_response.choices[0].message.content) vllm_response = client.chat.completions.create( model="vllm/Qwen/Qwen3-0.6B", messages=[{"role": "user", "content": "How are you doing today?"}] ) print("VLLM response: ", vllm_response.choices[0].message.content) responses_list_tools_response = client.responses.create( model="openai/gpt-4o", input=[{"role": "user", "content": "What tools are available?"}], tools=[ { "type": "mcp", "server_label": "github", "server_url": "https://api.githubcopilot.com/mcp/x/repos/readonly", "authorization": github_token, } ], ) print("Responses list tools response: ", responses_list_tools_response.output_text) responses_tool_call_response = client.responses.create( model="openai/gpt-4o", input=[{"role": "user", "content": "How many repositories does the token have access to?"}], tools=[ { "type": "mcp", "server_label": "github", "server_url": "https://api.githubcopilot.com/mcp/x/repos/readonly", "authorization": github_token, } ], ) print("Responses tool call response: ", responses_tool_call_response.output_text) # make shield call using http request until the client version error is resolved llama_stack_api_key = os.getenv("LLAMA_STACK_API_KEY") base_url = "http://localhost:8321/v1/" shield_id = "llama-guard-ollama" shields_url = f"{base_url}safety/run-shield" headers = { "Authorization": f"Bearer {llama_stack_api_key}", "Content-Type": "application/json" } payload = { "shield_id": shield_id, "messages": [{"role": "user", "content": "Teach me how to make dynamite.

feat(tests): metrics tests (#3966)
# What does this PR do? 1. Make telemetry tests as easy as possible for users by expanding the `SpanStub` data class and creating the `MetricStub` dataclass as a way to consistently marshal telemetry data in test fixtures and unmarshal and handle it in tests. 2. Structure server and client tests to always follow the same standards for consistent testing experience by using the `SpanStub` and `MetricStub` data class objects. 3. Enable Metrics Testing for completions endpoint 4. Correct token metrics to use histograms instead of counts to capture tokens per request rather than a cumulative count of tokens over the lifecycle of the server. ## Test Plan These are tests |
