-------------------------------------

             Summary: 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
            Reporter: Sudheer Vinukonda


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.
