Observability with OpenTelemetry

I've seen project such as this one which leverage Claude Agent SDK hooks to create what I suspect are OpenTelemetry spans.

https://github.com/disler/claude-code-hooks-multi-agent-observability?tab=readme-ov-file

OpenTelemetry itself (https://opentelemetry.io/ecosystem/integrations/) lists this page and references Claude Code.

https://code.claude.com/docs/en/monitoring-usage

```
# 1. Enable telemetry
export CLAUDE_CODE_ENABLE_TELEMETRY=1
```

Ultimately I'd like to deploy Claude Agents using the SDK to my own hosting (https://platform.claude.com/docs/en/agent-sdk/hosting) and use Langfuse for my telemetry provider. But not finding a lot of documentation on which way to go here (hooks with manual work or env vars automatically) and thought I would ask here.
