ASF GitHub Bot commented on TS-3072: ------------------------------------ Github user SolidWallOfCode commented on the pull request: https://github.com/apache/trafficserver/pull/350#issuecomment-161026974 James - a `uintptr_t` instead of `ContFlags` would require the assumption a continuation always runs on the same thread, which is not the case. `ContFlags` ensures that the continuation gets the thread based flags regardless of the thread on which it executes. On the other hand if you mean doing the thread specific stuff in `Continuation` I would think it's clearly better to isolate that stuff in `ContFlags`. > 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 > Assignee: Susan Hinrichs > Labels: Yahoo > Fix For: 6.1.0 > > Attachments: ts-3072.diff > > > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
