             Summary: Add milestone data for API times
                 Key: TS-3436
                 URL: https://issues.apache.org/jira/browse/TS-3436
             Project: Traffic Server
          Issue Type: Improvement
          Components: Core
            Reporter: Alan M. Carroll


Add two new milestones that track API time, "active" and "total". These are reasonably equivalent to "wall clock time" and "cpu time" concepts for process. The total time measures how long, in real time, a transaction spends involved with API callouts in plugins. The active time tracks the amount of time spent in an API callout. When these two values are different this means time is being spent either in lock contention to run the plugin continuation or waiting for the plugin to re-enable the transaction. Originally I had just the "total" counter but I think the ability to detect contention and wait is very valuable.
