Sönke Liebau commented on KAFKA-1440:
-------------------------------------
Looking through some old tickets and came across this. While certainly useful
in principle, this seems like a fairly large piece of work by now. Can we close
this, or is this something that someone feels strongly about and wants to look
at?
> Per-request tracing
> -------------------
>
> Key: KAFKA-1440
> URL: https://issues.apache.org/jira/browse/KAFKA-1440
> Project: Kafka
> Issue Type: Improvement
> Components: clients
> Reporter: Todd Palino
> Priority: Major
>
> Could we have a flag in requests (potentially in the header for all requests,
> but at least for produce and fetch) that would enable tracing for that
> request. Currently, if we want to debug an issue with a request, we need to
> turn on trace level logging for the entire broker. If the client could ask
> for the request to be traced, we could then log detailed information for just
> that request.
> Ideally, this would be available as a flag that can be enabled in the client
> via JMX, so it could be done without needing to restart the client
> application.
