Traces

    Live tail

    Watch traces land while you run the app locally, without the list moving under you.

    After this page you can leave Traces open while developing and see each request arrive, then open the newest one and re-run its prompt in the Playground.

    Turn on Live in the toolbar of the trace list. The page polls the Environment every 15 seconds; a countdown shows the next poll, and new rows animate in at the top with their chips filling in as spans arrive. A trace sent by the SDK appears within about one poll.

    Scrolling down pauses insertion: a banner counts the traces being held (“7 new traces held”) and Resume and jump to top inserts them. Opening a trace pauses the tail; Back resumes it. The newest row is one click from Open in playground, which seeds the chat with the prompt just sent.
