🚀 Quick Start

Installation

pip install traccia

Basic Usage

from traccia import init, observe

# Initialize (auto-loads from traccia.toml if present)
init()

# Trace any function
@observe()
def my_function(x, y):
    return x + y

# That's it! Traces are automatically created and exported
result = my_function(2, 3)

With LLM Calls

from traccia import init, observe
from openai import OpenAI

init()  # Auto-patches OpenAI

client = OpenAI()

@observe(as_type="llm")
def generate_text(prompt: str) -> str:
    response = client.chat.completions.create(
        model="gpt-4",
        messages=[{"role": "user", "content": prompt}]
    )
    return response.choices[0].message.content

# Automatically tracks: model, tokens, cost, prompt, completion, latency
text = generate_text("Write a haiku about Python")

LangChain

Create a callback handler and pass it to config={"callbacks": [traccia_handler]}. Install the optional extra: pip install traccia[langchain].

from traccia import init
from traccia.integrations.langchain import CallbackHandler  # or TracciaCallbackHandler
from langchain_openai import ChatOpenAI

init()

# Create Traccia handler (no args)
traccia_handler = CallbackHandler()

# Use with any LangChain runnable
llm = ChatOpenAI(model="gpt-4o-mini")
result = llm.invoke(
    "Tell me a joke",
    config={"callbacks": [traccia_handler]}
)

Spans for LLM/chat model runs are created automatically with the same attributes as direct OpenAI instrumentation (model, prompt, usage, cost).

Note: pip install traccia[langchain] installs traccia plus langchain-core; you need this extra to use the callback handler. If you already have langchain-core (e.g. from langchain or langchain-openai), base pip install traccia may be enough at runtime, but traccia[langchain] is the supported way to get a compatible dependency.

OpenAI Agents SDK

Traccia automatically detects and instruments the OpenAI Agents SDK when installed. No extra code needed:

from traccia import init
from agents import Agent, Runner

init()  # Automatically enables Agents SDK tracing

agent = Agent(
    name="Assistant",
    instructions="You are a helpful assistant"
)
result = Runner.run_sync(agent, "Write a haiku about recursion")

Configuration: Auto-enabled by default when openai-agents is installed. To disable:

init(openai_agents=False)  # Explicit parameter
# OR set environment variable: TRACCIA_OPENAI_AGENTS=false
# OR in traccia.toml under [instrumentation]: openai_agents = false

Compatibility: If you have openai-agents installed but don't use it (e.g., using LangChain or pure OpenAI instead), the integration is registered but never invoked—no overhead or extra spans.

CrewAI

Traccia automatically instruments CrewAI when it is installed in your environment.

from traccia import init
from crewai import Agent, Task, Crew, Process

init()  # Auto-enables CrewAI tracing when CrewAI is installed

researcher = Agent(role="Research Analyst", goal="Research a topic", llm="gpt-4o-mini")
task = Task(description="Research Shawn Michaels", agent=researcher)

crew = Crew(agents=[researcher], tasks=[task], process=Process.sequential, verbose=True)
result = crew.kickoff()

Traccia will create spans for the crew (crewai.crew.kickoff), each task (crewai.task.*), agents (crewai.agent.*), and underlying LLM calls, which nest under the existing OpenAI spans.

Configuration: Auto-enabled by default when crewai is installed. To disable:

init(crewai=False)  # Explicit parameter
# OR set environment variable: TRACCIA_CREWAI=false
# OR in traccia.toml under [instrumentation]: crewai = false

📖 Configuration

Configuration Precedence

Traccia merges configuration from multiple sources with the following priority (highest to lowest):

1. Explicit parameters — init(endpoint="...", agent_id="...") or start_tracing(...)
2. Environment variables — TRACCIA_ENDPOINT, TRACCIA_AGENT_ID, etc.
3. Config file — traccia.toml (current directory) or ~/.traccia/config.toml
4. Defaults — Built-in SDK defaults

Example: If you set TRACCIA_ENDPOINT in your environment and pass endpoint=... to init(), the explicit parameter wins.

---

Configuration File

Create a traccia.toml file in your project root:

traccia config init

This creates a template config file:

[tracing]
# API key — required for the Traccia platform, not needed for local OTLP backends
api_key = ""

# Endpoint URL for OTLP trace ingestion (default: Traccia platform)
# For local OTLP backends use e.g. endpoint = "http://localhost:4318/v1/traces"
endpoint = "https://api.traccia.ai/v2/traces"

sample_rate = 1.0           # 0.0 to 1.0
auto_start_trace = true     # Auto-start root trace on init
auto_trace_name = "root"    # Name for auto-started trace
use_otlp = true             # Use OTLP exporter
# service_name = "my-app"   # Optional service name
# service_role has no env var — pass via init(service_role="orchestrator")

[exporters]
# Only enable ONE exporter at a time
enable_console = false        # Print traces to console
enable_file = false           # Write traces to file
file_exporter_path = "traces.jsonl"

max_block_ms = 100              # Max ms to block before dropping
max_export_batch_size = 512     # Spans per export batch
schedule_delay_millis = 5000    # Delay between batches

[metrics]
enable_metrics = true           # Enable OpenTelemetry metrics
# metrics_endpoint = ""         # Defaults to {traces_base}/v2/metrics
metrics_sample_rate = 1.0       # Metrics sampling rate (1.0 = 100%)

[runtime]

# session_id = ""
# user_id = ""
# tenant_id = ""
# project_id = ""
# agent_id = ""   # Single-agent: set in code or TRACCIA_AGENT_ID
# agent_name = ""
# env = ""        # e.g. production, staging, dev

[logging]
debug = false                   # Enable debug logging
enable_span_logging = false     # Enable span-level logging

[advanced]
# attr_truncation_limit = 1000  # Max attribute value length

Default endpoint

If you do not set endpoint (in config, environment, or when calling init() / start_tracing()), the SDK uses the Traccia platform by default (https://api.traccia.ai/v2/traces). You can override it to send traces to your own OTLP-compatible backend.

The default is defined in traccia.config: DEFAULT_OTLP_TRACE_ENDPOINT. The alias DEFAULT_ENDPOINT is kept for backward compatibility (same value).

OTLP Backend Compatibility

Traccia is fully OTLP-compatible and works with:

• Grafana Tempo - http://tempo:4318/v1/traces
• Jaeger - http://jaeger:4318/v1/traces
• Zipkin - Configure via OTLP endpoint
• SigNoz - Self-hosted observability platform
• Traccia Platform - https://api.traccia.ai/v2/traces (requires API key)

Environment Variables

All config parameters can be set via environment variables with the TRACCIA_ prefix:

Tracing: TRACCIA_API_KEY, TRACCIA_ENDPOINT, TRACCIA_SAMPLE_RATE, TRACCIA_AUTO_START_TRACE, TRACCIA_AUTO_TRACE_NAME, TRACCIA_USE_OTLP, TRACCIA_SERVICE_NAME

Exporters: TRACCIA_ENABLE_CONSOLE, TRACCIA_ENABLE_FILE, TRACCIA_FILE_PATH, TRACCIA_RESET_TRACE_FILE

Instrumentation: TRACCIA_ENABLE_PATCHING, TRACCIA_ENABLE_TOKEN_COUNTING, TRACCIA_ENABLE_COSTS, TRACCIA_AUTO_INSTRUMENT_TOOLS, TRACCIA_MAX_TOOL_SPANS, TRACCIA_MAX_SPAN_DEPTH, TRACCIA_OPENAI_AGENTS, TRACCIA_CREWAI

Rate Limiting: TRACCIA_MAX_SPANS_PER_SECOND, TRACCIA_MAX_QUEUE_SIZE, TRACCIA_MAX_BLOCK_MS, TRACCIA_MAX_EXPORT_BATCH_SIZE, TRACCIA_SCHEDULE_DELAY_MILLIS

Runtime: TRACCIA_SESSION_ID, TRACCIA_USER_ID, TRACCIA_TENANT_ID, TRACCIA_PROJECT_ID, TRACCIA_AGENT_ID, TRACCIA_AGENT_NAME, TRACCIA_ENV

Legacy alias: TRACCIA_PROJECT (maps to project_id)

Logging: TRACCIA_DEBUG, TRACCIA_ENABLE_SPAN_LOGGING

Advanced: TRACCIA_ATTR_TRUNCATION_LIMIT

Programmatic Configuration

from traccia import init

# Override config programmatically (including agent identity for single-agent services)
init(
    endpoint="http://tempo:4318/v1/traces",
    sample_rate=0.5,
    enable_costs=True,
    max_spans_per_second=100.0,
    agent_id="my-agent",
    agent_name="My Agent",
    env="production",
)

Multi-Agent Orchestrator Services

For services that orchestrate many logical agents in one process, set a service role and scope per-run identity:

from traccia import init, runtime_config

init(
    service_name="my-multi-agent-api",
    service_role="orchestrator",
    auto_start_trace=False,
)

with runtime_config.run_identity(agent_id="billing-agent", agent_name="Billing Agent", env="production"):
    # run one logical agent task
    ...

This prevents the host service from being registered as a synthetic agent in the Traccia platform.

Safe Parallel Runs in One Process

If one process runs many agents concurrently (for example, an API server or orchestrator), use this pattern:

• Call init() once per process (for example at startup), not per request.
• Wrap each logical "run" in runtime_config.run_identity(...) to set agent id/name/env for that run.
• Do not call stop_tracing() per request; use force_flush() to flush spans/metrics after a run without shutting down the provider.

from traccia import init, span, force_flush, runtime_config

init(service_name="multi-agent-service", auto_start_trace=False)

def run_agent(agent_id: str, env: str, payload: dict):
    # Scope identity to this run only
    with runtime_config.run_identity(agent_id=agent_id, agent_name=agent_id, env=env):
        with span("agent.run") as root:
            root.set_attribute("agent.id", agent_id)
            root.set_attribute("agent.run.mode", "api")
            # ... your agent logic here ...

    # Flush without tearing down the global provider
    force_flush(5.0)

🎯 Usage Guide

The @observe Decorator

The @observe decorator is the primary way to instrument your code:

from traccia import observe

# Basic usage
@observe()
def process_data(data):
    return transform(data)

# Custom span name
@observe(name="data_pipeline")
def process_data(data):
    return transform(data)

# Add custom attributes
@observe(attributes={"version": "2.0", "env": "prod"})
def process_data(data):
    return transform(data)

# Specify span type
@observe(as_type="llm")  # "span", "llm", "tool"
def call_llm():
    pass

# Skip capturing specific arguments
@observe(skip_args=["password", "secret"])
def authenticate(username, password):
    pass

# Skip capturing result (for large returns)
@observe(skip_result=True)
def fetch_large_dataset():
    return huge_data

Available Parameters:

• name (str, optional): Custom span name (defaults to function name)
• attributes (dict, optional): Initial span attributes
• as_type (str): Span type - "span", "llm", or "tool"
• skip_args (list, optional): List of argument names to skip capturing
• skip_result (bool): Skip capturing the return value

Async Functions

@observe works seamlessly with async functions:

@observe()
async def async_task(x):
    await asyncio.sleep(1)
    return x * 2

result = await async_task(5)

Manual Span Creation

For more control, create spans manually:

from traccia import get_tracer, span

# Using convenience function
with span("operation_name") as s:
    s.set_attribute("key", "value")
    s.add_event("checkpoint_reached")
    do_work()

# Using tracer directly
tracer = get_tracer("my_service")
with tracer.start_as_current_span("operation") as s:
    s.set_attribute("user_id", 123)
    do_work()

Error Handling

Traccia automatically captures and records errors:

@observe()
def failing_function():
    raise ValueError("Something went wrong")

# Span will contain:
# - error.type: "ValueError"
# - error.message: "Something went wrong"
# - error.stack_trace: (truncated stack trace)
# - span status: ERROR

Nested Spans

Spans are automatically nested based on call hierarchy:

@observe()
def parent_operation():
    child_operation()
    return "done"

@observe()
def child_operation():
    grandchild_operation()

@observe()
def grandchild_operation():
    pass

# Creates nested span hierarchy:
# parent_operation
#   └── child_operation
#       └── grandchild_operation

---

🛠️ CLI Tools

Traccia includes a powerful CLI for configuration and diagnostics:

traccia config init

Create a new traccia.toml configuration file:

traccia config init
traccia config init --force  # Overwrite existing

traccia doctor

Validate configuration and diagnose issues:

traccia doctor

# Output:
# 🩺 Running Traccia configuration diagnostics...
# 
# ✅ Found config file: ./traccia.toml
# ✅ Configuration is valid
# 
# 📊 Configuration summary:
#    • API Key: ❌ Not set (optional)
#    • Endpoint: https://api.traccia.ai/v2/traces
#    • Sample Rate: 1.0
#    • OTLP Exporter: ✅ Enabled

traccia check

Test connectivity to your exporter endpoint:

traccia check
traccia check --endpoint http://tempo:4318/v1/traces

🎨 Advanced Features

Rate Limiting

Protect your infrastructure with built-in rate limiting:

[rate_limiting]
max_spans_per_second = 100.0  # Limit to 100 spans/sec
max_queue_size = 5000         # Max buffered spans
max_block_ms = 100             # Block up to 100ms before dropping

Behavior:

1. Try to acquire capacity immediately
2. If unavailable, block for up to max_block_ms
3. If still unavailable, drop span and log warning

When spans are dropped due to rate limiting, warnings are logged to help you monitor and adjust limits.

Sampling

Control trace volume with sampling:

# Sample 10% of traces
init(sample_rate=0.1)

# Sampling is applied at trace creation time
# Traces are either fully included or fully excluded

Token Counting & Cost Calculation

Automatic for supported LLM providers (OpenAI, Anthropic):

@observe(as_type="llm")
def call_openai(prompt):
    response = client.chat.completions.create(
        model="gpt-4",
        messages=[{"role": "user", "content": prompt}]
    )
    return response.choices[0].message.content

# Span automatically includes:
# - llm.token.prompt_tokens
# - llm.token.completion_tokens
# - llm.token.total_tokens
# - llm.cost.total (in USD)

Metrics

Traccia emits OTEL-compliant metrics for accurate cost and token tracking, independent of trace sampling.

Why Metrics?

With trace sampling (e.g., sample_rate=0.1), only 10% of traces are exported. Cost calculated from traces will be 10x underestimated. Metrics solve this by recording data for every LLM call, regardless of sampling.

Default Metrics

Traccia automatically emits these metrics:

Metric	Type	Unit	Description
gen_ai.client.token.usage	Histogram	{token}	Input/output tokens per call
gen_ai.client.operation.duration	Histogram	s	LLM operation duration
gen_ai.client.operation.cost	Histogram	usd	Cost per call (USD)
gen_ai.client.completions.exceptions	Counter	1	Exception count
gen_ai.agent.runs	Counter	1	Agent runs (CrewAI, OpenAI Agents)
gen_ai.agent.turns	Counter	1	Agent turns
gen_ai.agent.execution_time	Histogram	s	Agent execution time

Attributes: gen_ai.system (openai, anthropic), gen_ai.request.model, gen_ai.agent.id, gen_ai.agent.name

Configuration

from traccia import init

init(
    enable_metrics=True,  # Default: True
    metrics_endpoint="https://your-backend.com/v2/metrics",  
    metrics_sample_rate=1.0,  # Default: 1.0 (100%)
)

Or via traccia.toml:

[metrics]
enable_metrics = true
metrics_endpoint = "https://your-backend.com/v2/metrics"
metrics_sample_rate = 1.0

Or via environment variables:

export TRACCIA_ENABLE_METRICS=true
export TRACCIA_METRICS_ENDPOINT=https://your-backend.com/v2/metrics
export TRACCIA_METRICS_SAMPLE_RATE=1.0

Custom Metrics

Record your own metrics:

from traccia.metrics import record_counter, record_histogram

# Record a counter
record_counter("my_custom_events", 1, {"event_type": "user_action"})

# Record a histogram
record_histogram("my_custom_latency", 0.123, {"service": "api"}, unit="s")

Agent Metrics vs. Plain LLM Calls

Agent-level metrics (such as gen_ai.agent.runs and gen_ai.agent.execution_time) are only emitted when Traccia can see a real agent lifecycle (for example, CrewAI crews or OpenAI Agents SDK runs). For plain OpenAI/Anthropic calls and most simple LangChain usages, you will still get full LLM metrics (gen_ai.client.*), but no agent metrics unless you build an explicit agent abstraction on top.

🔧 Troubleshooting

Enable Debug Logging

import logging
logging.basicConfig(level=logging.DEBUG)

# Or via config
init(debug=True)

# Or via env var
# TRACCIA_DEBUG=1 python your_script.py

Common Issues

Traces not appearing

1. Check connectivity: traccia check
2. Validate config: traccia doctor
3. Enable debug logging
4. Verify endpoint is correct and accessible

High memory usage

• Reduce max_queue_size in rate limiting config
• Lower sample_rate to reduce volume
• Enable rate limiting with max_spans_per_second

Spans being dropped

• Check rate limiter logs for warnings
• Increase max_spans_per_second if set
• Increase max_queue_size if spans are queued
• Check traccia doctor output

Instrumentation vs Integrations

• traccia.instrumentation.*: Infrastructure and vendor instrumentation.

  • HTTP client/server helpers (including FastAPI middleware).
  • Vendor SDK hooks and monkey patching (e.g., OpenAI, Anthropic, requests).
  • Decorators and utilities used for auto-instrumenting arbitrary functions.

• traccia.integrations.*: AI/agent framework integrations.

  • Adapters that plug into higher-level frameworks via their official extension points (e.g., LangChain callbacks).
  • Work at the level of chains, tools, agents, and workflows rather than raw HTTP or SDK calls.
