OpenTelemetry exporter, self-hosted

Where is the appropriate entrypoint for creating sdk.start() where sdk = new NodeSDK({...}) from @opentelemetry/sdk-node? It should ideally be invoked only once, on server start. I thought I could achieve this with a nitro plugin, but I did not manage to get it to run. I setup nitro.config.js (next to vite.config.js, so in the same directory where src/ lives, not in src/). I see that the config is called on startup (added a log in there). I tried creating server/plugins/foo.ts and src/server/plugins/foo.ts and registering it in the nitro config, but it never got called. Perhaps other option is to call it somewhere inside server.ts, which looks like this for me: 
...

const handlerFactory = createCustomHandler(
  createStartHandler({
    createRouter,
  }),
);

export default defineHandlerCallback(async (event) => {
  const startHandler = await handlerFactory(defaultStreamHandler);
  return startHandler(event);
});
...

const handlerFactory = createCustomHandler(
  createStartHandler({
    createRouter,
  }),
);

export default defineHandlerCallback(async (event) => {
  const startHandler = await handlerFactory(defaultStreamHandler);
  return startHandler(event);
});
