Uri - I agree with your point in general as well, but, I think it's
arguable whether to treat this as a *feature* that isn't needed in the core. I
can say, with certainty, that a majority (if not all) of production deployments
would be benefitted from this capability. Having this in the core (even in its
simplest form) already provides a great benefit to them, in terms of simplicity
in configuration and use. Having to deploy a plugin and maintain it's
configuration separately only makes it more complicated and less easy to use
for general operations.
Fwiw, we also have a number of similar features (which could have all been
done using plugins too) in the core that are used extensively by operations and
plugin developers alike (e.g @ headers).

> 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.
