Uri Shachar commented on TS-1079: --------------------------------- I've retested the perf a couple of times -- can't see any significant change (Tested with debug enabled and disabled). > Add an API function to turn debugging on for specific transactions/sessions > --------------------------------------------------------------------------- > > Key: TS-1079 > URL: https://issues.apache.org/jira/browse/TS-1079 > Project: Traffic Server > Issue Type: Improvement > Components: Core, HTTP > Reporter: Uri Shachar > Assignee: Leif Hedstrom > Priority: Minor > Fix For: 3.1.4 > > Attachments: debug_specific.patch, debug_specific_2.patch, > debug_specific_3.patch, debug_specific_4.patch > > Original Estimate: 72h > Remaining Estimate: 72h > > When attempting to troubleshoot issues on a production ATS system, it > is often impossible/difficult to turn on any of the 'high-volume' debug tags > like http due to the performance impact. > > This enhancement allows a plugin to set a debug flag for a specific txn/ssn, > and replaces some of the internal Debug calls with a new function that checks > if the flag is turned on, and outputs the debug line regardless of the tag if > it is (The diags enable/disable flag is still taken into account). > The API will also have TSDebugSpecific in order to allow plugins to use the > same functionality. > In addition, we might consider adding an internal config file (remap-like) to > allow turning this flag on without plugin intervention. > -- This message is automatically generated by JIRA.
