Invocation traces and request timelines

You can inspect how a function invoke moved through the platform with zoomable timelines, multiplexed request bars, and linked Traces in Invocations.

Timelines and multiplexed requests

Open an invocation from Invocations to see a zoomable timeline of function work. When one warm isolate serves concurrent requests, the Overview and Trace show those requests as separate bars on the same invoke.

Link from a Logs row into the matching invocation so you do not re-find the same event. Cold start and AWS billed stay on the detail metrics next to the Trace.

When traces help

Use traces after a deploy when p95 latency moves and charts alone do not explain why. Compare two invocations from before and after the release to see which span grew.

For a single request, open Logs, select the row, and use the Trace tab. Invocations adds the invocation-level Trace, multiplexed request bars, and links back into Logs when you need more depth.
