> Instrument task scheduling pipeline
> -----------------------------------
>
> Key: AURORA-914
> URL: https://issues.apache.org/jira/browse/AURORA-914
> Project: Aurora
> Issue Type: Task
> Components: Scheduler
> Reporter: Maxim Khutornenko
> Assignee: Maxim Khutornenko
> Fix For: 0.7.0
>
>
> We need a better instrumentation of the task scheduling loop to helps us
> troubleshoot scheduling performance problems. Specifically:
> - Add {{@Timed}} in TaskScheduler.schedule() (inside the write lock)
> - Add {{@Timed}} in OfferQueue.launchFirst()
> - Add {{@Timed}} for every iteration of the OfferQueue.launchFirst() loop
> - Differentiate between "static" (e.g.: resource shortage) vs. "dynamic"
> (e.g.: constraint mismatch) Vetos and add a counter to track each Veto type.
