----------------------------------------
Summary: 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
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.
