# Debug local LLM and agent traces with Axon

Run Axon as a local OpenTelemetry endpoint and dashboard for inspecting LangChain and instrumented agent traces without sending run data to a cloud service.

## Prerequisites

Node.js, @axon-ai/cli, LangChain or OpenTelemetry-instrumented agent application, local OTLP endpoint

## Installation

Install or set up from the source-backed instructions:

Install with `npm install -g @axon-ai/cli`, run `axon-ai init --project ` inside the target project, then run `axon-ai start`. Point LangChain, OpenLLMetry, OpenInference, or raw OTEL exporters at `http://localhost:4000/v1/traces` or the configured port, then inspect traces in the local dashboard.
