Tracer & Auto-Instrumentation

Overview

Valiqor tracing captures the full execution flow of your AI application — LLM calls, tool executions, retrieval steps, and custom logic — as structured traces with spans. Three levels of instrumentation are available:

Zero-config — import valiqor.auto and traces are captured automatically
Decorators — @trace_workflow and @trace_function for explicit control
Manual spans — Full control via TracerV2 for complex pipelines

Zero-Config Auto-Instrumentation

The simplest way to start tracing. Add one import at the top of your application:

import valiqor.auto

This reads your configuration from environment variables or .valiqorrc and automatically patches supported providers (OpenAI, Anthropic, LangChain, Ollama, Agno).

`autolog()` Function

Enable auto-instrumentation programmatically with more control:

from valiqor.trace import autolog

# Enable all supported providers
autolog()

# Enable specific providers only
autolog(providers=["openai", "langchain"])

`disable_autolog()`

Disable auto-instrumentation:

from valiqor.trace import disable_autolog

disable_autolog()  # Disable all
disable_autolog(providers=["openai"])  # Disable specific

Provider-Specific Shortcuts

from valiqor.trace import (
    openai_autolog,
    anthropic_autolog,
    langchain_autolog,
    ollama_autolog,
    agno_autolog,
)

openai_autolog()       # Enable OpenAI tracing only
anthropic_autolog()    # Enable Anthropic tracing only
langchain_autolog()    # Enable LangChain tracing only
ollama_autolog()       # Enable Ollama tracing only
agno_autolog()         # Enable Agno tracing only

`configure()` Function

Configure the tracing system programmatically:

from valiqor.trace import configure

configure(
    api_key="your-api-key",
    project_name="my-app",
    app_name="chatbot",
    app_version="1.2.0",
    environment="production",
    trace_dir="valiqor_output/traces",
    backend_url="https://api.valiqor.com",
    auto_trace=True,
    local_export=True,
    debug=False,
)

Decorators

`@trace_workflow`

Create a trace for a workflow. Works as both a context manager and a decorator.

from valiqor.trace import trace_workflow

@trace_workflow(name="qa_pipeline")
def answer_question(question: str) -> str:
    context = retrieve_docs(question)
    return generate_answer(question, context)

answer_question("What is RAG?")

Parameter	Type	Default	Description
`name`	`str`	`"workflow"`	Name for this trace/workflow.
`input_data`	`Dict`	`None`	Optional input data to attach to the trace.

`@trace_function`

Create a span under the active trace for a function call.

from valiqor.trace import trace_function

@trace_function(name="retrieve_docs")
def retrieve_docs(query: str) -> List[str]:
    return vector_db.search(query)

Parameter	Type	Default	Description
`name`	`str`	`None`	Span name. Defaults to the function name.
`input_fields`	`List`	`None`	Which function arguments to capture.
`capture_input`	`bool`	`True`	Whether to capture function input arguments.
`capture_output`	`bool`	`True`	Whether to capture function return value.

Conversation Tracking

For multi-turn conversational agents, group multiple interactions into a single trace:

from valiqor.trace import start_conversation_trace, end_conversation_trace

# Start a conversation trace
trace_id = start_conversation_trace(name="support_chat")

# ... handle multiple user turns ...

# End and finalize the conversation trace
end_conversation_trace()

`TracerV2` — Manual Tracing

For full control over trace and span lifecycle:

from valiqor.trace import TracerV2

Constructor

TracerV2(
    app: Optional[Dict[str, str]] = None,
    exporters=None,
    ring_size: int = 200,
    trace_dir: str = "valiqor_output/traces",
    backend_url: str = None,
    api_key: str = None,
    project_name: str = None,
    environment: str = None,
)

Parameter	Type	Default	Description
`app`	`Dict[str, str]`	—	App metadata, e.g. `{"name": "my-app", "version": "1.0"}`.
`exporters`	`list`	`None`	List of exporter instances.
`ring_size`	`int`	`200`	Max events in the ring buffer.
`trace_dir`	`str`	`"valiqor_output/traces"`	Local output directory.
`backend_url`	`str`	`None`	Backend URL for cloud export.

Trace Lifecycle

# Start a trace
trace_id = tracer.start_trace(
    name="qa_pipeline",
    input_state={"question": "What is RAG?"},
    user_id="user-123",
    session_id="session-456"
)

# ... do work with spans ...

# End the trace
result = tracer.end_trace(output_state={"answer": "RAG is..."})

Span Lifecycle

# Start a span
span = tracer.start_span(
    name="retrieve_documents",
    stage=ValiqorStage.RETRIEVAL,
    span_kind=ValiqorSpanKind.RETRIEVER,
    attributes={"query": "What is RAG?"}
)

# Do work...

# Finish the span
tracer.finish_span(span, status="success")

Message Logging

tracer.add_message({"role": "user", "content": "What is RAG?"})
tracer.add_message({"role": "assistant", "content": "RAG stands for..."})

RAG-Specific Methods

TracerV2 provides specialized methods for tracing RAG pipelines:

`track_retrieval()`

Track a retrieval step with document hits.

from valiqor.trace import DocumentHit

span = tracer.start_retrieval_span("vectordb", "What is RAG?")
retrieval_info = tracer.track_retrieval(
    span=span,
    retriever="vectordb",
    query="What is RAG?",
    hits=[
        DocumentHit(doc_id="doc-1", rank=1, score=0.95, snippet_preview="RAG is..."),
        DocumentHit(doc_id="doc-2", rank=2, score=0.87, snippet_preview="Retrieval...")
    ],
    embedding_model="text-embedding-3-small",
    top_k=5,
    latency_ms=45.2
)

`track_generation()`

Track a generation step.

from valiqor.trace import Citation

span = tracer.start_generation_span("gpt-4o")
gen_info = tracer.track_generation(
    span=span,
    answer="RAG stands for Retrieval-Augmented Generation...",
    model_used="gpt-4o",
    citations=[Citation(doc_id="doc-1", confidence=0.95)],
    latency_ms=1200.0
)

`track_rag_pipeline()`

Track the entire RAG pipeline in one call.

span = tracer.start_rag_pipeline_span(query="What is RAG?")
retrieval_info, gen_info = tracer.track_rag_pipeline(
    span=span,
    query="What is RAG?",
    retrieval_results=[DocumentHit(doc_id="doc-1", rank=1, score=0.95)],
    answer="RAG stands for...",
    retriever_type="vectordb",
    generation_model="gpt-4o"
)
