VoltAgent ships its own observability layer. Plug an OTLP exporter into VoltAgentObservability, then pass userId / conversationId per call.

​
1. Install

Already have @voltagent/core and @opentelemetry/exporter-trace-otlp-proto? Skip. No setup yet? 
npm install @voltagent/core @opentelemetry/exporter-trace-otlp-proto @opentelemetry/sdk-trace-node

​
2. Wire the OTel exporter pointing at Agnost

Already have VoltAgentObservability? Append a span processor for Agnost to the existing spanProcessors array: 
import { OTLPTraceExporter } from '@opentelemetry/exporter-trace-otlp-proto';
import { BatchSpanProcessor } from '@opentelemetry/sdk-trace-node';

const agnostProcessor = new BatchSpanProcessor(
  new OTLPTraceExporter({
    url: 'https://otel.agnost.ai/v1/traces',
    headers: { 'X-Agnost-Org-ID': process.env.AGNOST_ORG_ID! },
  }),
);

// Inside your existing VoltAgentObservability:
spanProcessors: [
  // ...your existing processors,
  agnostProcessor,
]
No Observability yet? Full setup: 
import { VoltAgent, VoltAgentObservability } from '@voltagent/core';
import { OTLPTraceExporter } from '@opentelemetry/exporter-trace-otlp-proto';
import { BatchSpanProcessor } from '@opentelemetry/sdk-trace-node';

const exporter = new OTLPTraceExporter({
  url: 'https://otel.agnost.ai/v1/traces',
  headers: { 'X-Agnost-Org-ID': process.env.AGNOST_ORG_ID! },
});

const observability = new VoltAgentObservability({
  spanProcessors: [new BatchSpanProcessor(exporter)],
});

new VoltAgent({ agents: { agent }, observability });

​
3. Pass userId / conversationId per call

await agent.generateText('Hello', {
  userId: 'user-42',
  conversationId: 'conv-abc123',
});
VoltAgent maps userId → user.id and conversationId → conversation.id on every span — both read directly by Agnost for user / session grouping.
