[jira] [Created] (FLINK-16440) Extend SlotManager metrics and
status for dynamic slot allocation.
Xintong Song created FLINK-16440:
------------------------------------
Summary: Extend SlotManager metrics and status for dynamic slot allocation.
Key: FLINK-16440
URL: https://issues.apache.org/jira/browse/FLINK-16440
Project: Flink
Issue Type: Sub-task
Components: Runtime / Metrics
Reporter: Xintong Song
Fix For: 1.11.0
* Create a slotManagerMetricGroup in resourceManagerMetricGroup, pass it into SM and register slot related metrics there.
* This allows registering different metrics for different SM implementation.
* For backwards compatibility, the slotManagerMetricGroup should have the same path as the resourceManagerMetricGroup.
* Extend ResourceOverview and TaskManagerInfo to contain TM total / free / allocated resources.
* Need to add methods to SM for getting TM resource status.
* For SlotManagerImpl,
* The existing methods for getting number of registered / free slots need no changes.
* TM resource status can be computed from TaskExecutorProcessSpec, slot profiles and number of free slots.
