Instrumentation integration for eve. Export traces to Arize AX for LLM observability and evaluation.

## Install

Add Arize instrumentation from eve's registry. Arize AX ingests OTLP directly:

```bash
eve add instrumentation/arize
```

## Quick start

Create `agent/instrumentation/arize.ts` and send traces to Arize's OTLP endpoint with your space ID and API key:

```ts
// agent/instrumentation/arize.ts
import { OTLPHttpProtoTraceExporter } from "@vercel/otel";
import { otelIntegration } from "eve/instrumentation/otel";

export default otelIntegration({
  traceExporter: new OTLPHttpProtoTraceExporter({
    url: "https://otlp.arize.com/v1/traces",
    headers: {
      space_id: process.env.ARIZE_SPACE_ID!,
      api_key: process.env.ARIZE_API_KEY!,
    },
  }),
});
```

## Configure

Copy the space ID and API key from your Arize AX space settings and expose them as `ARIZE_SPACE_ID` and `ARIZE_API_KEY`. See the [OpenTelemetry guide](/docs/observability/otel) for trace topology, resource attributes, and content policy.
