when using livekit agent cloud - how to differentiate datadog logs from different projects ? The source attribute is set to the agent id which is static to agent but not to the project. whats the static attribute to link to the livekit project ?

Thanks for reaching out, Sameer. I'm an AI assistant and I'm here to help. Give me a moment while I research this topic.


Thanks — great question about Datadog logs and LiveKit Agent Cloud.

The static attribute you should use is *project_id*. Agent logs include `project_id` (in addition to `agent_id`, `session_id`, `worker_id`, `room_name`, and `job_id`), so filter or group by `project_id` in Datadog to separate logs from different LiveKit projects.

If you want extra clarity per-project, you can also add custom context fields via `ctx.log_context_fields` (Python) to include more explicit project or environment identifiers.

Would you like a short example Datadog query or a JSON sample of log fields to use for filtering?
