--------------------------------------
Hi [~shenzhu0127],
Happy to see you are eager to work on this but I think there are still some
open questions. In particular how this fits in with FLINK-21513 and how we
ensure these metrics work for all deployment types and schedulers.
> Add additional availability timing metrics to Job lifecycle events

> URL: https://issues.apache.org/jira/browse/FLINK-23976
> Project: Flink
> Issue Type: Improvement
> Components: Runtime / Metrics
> Reporter: Seth Wiesman
> Priority: Major
> Labels: pull-request-available
>
> Flink currently contains a number of availability lifecycle metrics[1]
> showing how long it takes to move through different job status'. We propose
> adding two additional metrics; startingTime, and cancellingTime (open to
> bikeshedding on the metric names).
>
> * startingTime is the time it takes a job to get to running.
> * cancellingTime is the time spent in status CANCELLING
