Send data to a specific project

A space in Arize groups different projects together. Inside a space you can have multiple project names.

The lowest level logical separation of traces in Arize is currently done by the project_name.

# Import open-telemetry dependencies
from arize.otel import register

# Setup OTel via our convenience function
tracer_provider = register(
    space_id = "your-space-id", # in app space settings page
    api_key = "your-api-key", # in app space settings page
    project_name = "your-project-name", # name this to whatever you would like
)

The code below shows how to setup tracing to export spans to Arize. To see how to use our auto instrumentations see Tracing Integrations.

install dependencies:

npm install @opentelemetry/exporter-trace-otlp-grpc @grpc/grpc-js @opentelemetry/sdk-trace-base @opentelemetry/sdk-trace-node @opentelemetry/reources @opentelemetry/api

Create an instrumentation.ts file. That file should look like this:

import { registerInstrumentations } from "@opentelemetry/instrumentation";
import { ConsoleSpanExporter } from "@opentelemetry/sdk-trace-base";
import {
  NodeTracerProvider,
  SimpleSpanProcessor,
} from "@opentelemetry/sdk-trace-node";
import { Resource } from "@opentelemetry/resources";
import { 
  OTLPTraceExporter as GrpcOTLPTraceExporter 
} from "@opentelemetry/exporter-trace-otlp-grpc"; // Arize specific
import { diag, DiagConsoleLogger, DiagLogLevel } from "@opentelemetry/api";
import { Metadata } from "@grpc/grpc-js"

// For troubleshooting, set the log level to DiagLogLevel.DEBUG
diag.setLogger(new DiagConsoleLogger(), DiagLogLevel.DEBUG);

// Arize specific - Create metadata and add your headers
const metadata = new Metadata();

// Your Arize Space and API Keys, which can be found in the UI, see below
metadata.set('space_id', 'your-space-id');
metadata.set('api_key', 'your-api-key');

const provider = new NodeTracerProvider({
  resource: new Resource({
    // Arize specific - The name of a new or preexisting model you 
    // want to export spans to
    "model_id": "your-model-id",
    "model_version": "your-model-version"
  }),
});

provider.addSpanProcessor(new SimpleSpanProcessor(new ConsoleSpanExporter()));
provider.addSpanProcessor(
  new SimpleSpanProcessor(
    new GrpcOTLPTraceExporter({
      url: "https://otlp.arize.com/v1",
      metadata,
    }),
  ),
);

// Add auto instrumentatons here

provider.register();

This file needs to run at the entry point of your application, before any other code on your server runs. You can do this by importing it at the top of your entry point for example in something like server/app.ts:

import "./instrumentation"
// server startup

Or you can import it via a node command when you run your server as outline in the OpenTelemetry documentation using import or require:

# require
npx ts-node --require ./instrumentation.ts app.ts
# import
npx ts-node --import ./instrumentation.ts app.ts
# Or without ts-node something like
node --import ./dist/instrumentation.cjs ./dist/index.cjs

The space ID can be found in the space settings tab.

The the spaces can be added or changed at the top of the page.

The project_name maps to a use-case which can be selected by clicking on projects in the left navigation bar.
