James Peach commented on TS-3072:
---------------------------------
I'll be committing {{traffic_ctl}} today. From now on, please add any
management support to {{traffic_ctl}} rather than {{traffic_line}}.
> Debug logging for a single connection in production traffic.

> Key: TS-3072
> URL: https://issues.apache.org/jira/browse/TS-3072
> Project: Traffic Server
> Issue Type: Improvement
> Components: Core, Logging
> Affects Versions: 5.0.1
> Reporter: Sudheer Vinukonda
> Labels: Yahoo
> Fix For: 5.3.0
>
>
> Presently, when there's a production issue (e.g. TS-3049, TS-2983 etc), it is
> really hard to isolate/debug with the high traffic. Turning on debug logs in
> traffic is unfortunately not an option due to performance impacts. Even if
> you took a performance hit and turned on the logs, it is just as hard to
> separate out the logs for a single connection/transaction among the millions
> of the logs output in a short period of time.
> I think it would be good if there's a way to turn on debug logs in a
> controlled manner in production environment. One simple option is to support
> a config setting for example, with a client-ip, which when set, would turn on
> debug logs for any connection made by just that one client. If needed,
> instead of one client-ip, we may allow configuring up to 'n' (say, 5)
> client-ips.
> If there are other ideas, please comment.
