AI Agent Debugging & Tracing

Debug AI Agents Like a Pro

Follow instrumented LLM calls, retrievals, tool interactions, and agent steps in one trace.

AI agents are complex, non-deterministic, and opaque. Hierarchical tracing gives investigators a concrete execution record to inspect when something goes wrong.

The Challenge

Why Debugging AI Agents is So Hard

Traditional debugging tools (logs, metrics, profilers) were designed for deterministic software. AI agents are fundamentally different and require a different approach.

The Black Box Problem

LLMs are black boxes. You can see input and output, but not internal reasoning. When an agent produces a wrong answer, you don't know if it's a bad prompt, bad LLM response, or bad tool call.

Non-Deterministic Behavior

The same input can produce different outputs. This makes it hard to reproduce bugs and understand what went wrong. You can't just run the same input again.

Complex Workflows

Modern AI agents are complex multi-step workflows with LLM calls, tool interactions, and decision points. A single failure can be caused by any step.

Inadequate Logging

Traditional logging is insufficient. You need to see not just what happened, but why. What was the LLM's reasoning? What data did the tool return?

Debugging Without a Connected Trace

When prompts, model calls, retrievals, and tool results live in separate logs, investigators must reconstruct the execution path before they can test a hypothesis.

The Solution

Noveum.ai Tracing: Connected Execution Evidence

Use hierarchical tracing to connect the instrumented operations from an initial input to the final recorded output.

What Gets Traced

Supported integrations capture the callbacks they receive; context managers and custom spans cover application-specific operations

LLM Calls
Tool Calls
RAG Calls
API Calls
DB Queries
Custom Operations

Workflow Tracing

Instrument supported framework callbacks and add custom operations where your application needs more context.

  • Instrumented LLM calls with the fields your capture settings allow
  • Instrumented tool calls with available inputs, outputs, and timing
  • API calls and database queries you wrap as custom operations
  • Custom operations you define

Key Benefits

Why Teams Choose Noveum.ai Tracing

Debug faster, understand better, and deploy with confidence.

Reduce Debugging Time

Start from a connected execution record instead of reconstructing an agent run from unrelated logs.

Understand Agent Behavior

Inspect the operations and data your instrumentation recorded; tracing does not expose hidden model reasoning.

Improve Quality

By understanding what's going wrong, you can make targeted improvements. Fix root causes, not symptoms.

Optimize Performance

See which operations are slow. Identify bottlenecks and optimize them for better latency.

Build Confidence

Deploy agents with confidence knowing you can quickly debug any issues that arise.

Reduce Costs

Identify expensive operations and optimize LLM usage. Save on API costs with targeted improvements.

From Signal to Supporting Evidence

Filter to the affected trace, inspect its span hierarchy and raw attributes, and compare it with a healthy execution before deciding what to change.

Getting Started

How Tracing Works

Send a representative trace in three steps, then verify its captured fields before broadening coverage.

  1. 1

    Install the SDK

    Install the Noveum.ai Python SDK with a single command.

  2. 2

    Add Callback Handler

    Attach the callback handler to the LangChain invocations whose supported events you want to trace.

  3. 3

    View Traces

    After an instrumented invocation is ingested, open Explorer and verify its span hierarchy and attributes.

Install the SDK

Install the Noveum.ai Python SDK with a single command.

pip install noveum-trace

Add Callback Handler

Attach the callback handler to the LangChain invocations whose supported events you want to trace.

llm = ChatOpenAI(callbacks=[callback_handler])

View Traces

After an instrumented invocation is ingested, open Explorer and verify its span hierarchy and attributes.

Trace Exploration

The trace viewer exposes the execution context your instrumentation captured. You can:

  • 1View the full hierarchy of operations
  • 2Click any span to see detailed information
  • 3Inspect errors and form a root-cause hypothesis
  • 4Compare traces to find differences

Real-World Applications

How Teams Use Noveum.ai Tracing

See how developers use tracing to debug and optimize their agents.

Debugging Production Issues

When an agent fails in production, inspect the captured trace to find the operation and evidence most likely to explain the failure before deciding whether local reproduction is needed.

Example: A support agent gives wrong answers. The trace shows an LLM hallucination in step 3 of a 5-step workflow.

Performance Optimization

An agent is slow. See which operations take the most time and optimize them for better user experience.

Example: A captured trace attributes most measured latency to one tool call. The team changes that call and compares latency on a representative follow-up cohort.

Quality Improvement

An agent produces low-quality outputs. Trace execution to see where quality is degrading and fix the root cause.

Example: Poor outputs traced to context retrieval returning irrelevant documents. Fix the retrieval, fix the quality.

Multi-Agent Debugging

When a multi-agent system fails, instrument the relevant workflow boundaries and interactions so investigators can inspect the captured execution path.

Example: Agent A sends wrong data to Agent B. The trace shows exactly where the miscommunication happens.

vs. Traditional Logging

Logs are text-based and hard to parse. You have to grep through thousands of lines to find issues.

Noveum.ai

Structured, hierarchical traces that are easy to explore and understand visually.

vs. APM Tools (Datadog, New Relic)

Generic APM without AI-specific instrumentation may not retain the prompt, model, token, retrieval, tool, and evaluation context needed for agent investigation.

Noveum.ai

AI-specific tracing with LLM insights, cost tracking, and integration with evaluation.

vs. Custom Solutions

Building your own tracing system is expensive and time-consuming. Maintenance is a constant burden.

Noveum.ai

Battle-tested, proven solution that works out of the box with any framework.

Unique Features

AI-Specific

Designed specifically for AI agents, not generic software.

Hierarchical

See the hierarchical structure of recorded agent operations, not just flat logs.

Lightweight

Measure SDK overhead with your payload, network, batching, and flush settings before production rollout.

Framework-Agnostic

Works with LangChain, LangGraph, CrewAI, and any custom agents.

Integrated

Connects tracing with evaluation and NovaPilot analysis reports.

Recent Trace Access

Inspect traces after ingestion and refresh the selected time window when new traffic arrives.

Stop Flying Blind

Connect agent operations in hierarchical traces, inspect failures with context, and verify changes with evidence.
