--------------------------------------
[~Weijie Guo] Thanks for pinging me here.

Thanks for the proposal.
I think these metrics sound reasonable.
IIUC, they are checkpoint related task-level metrics.
I think we could use TraceReporter provided by FLINK-33695 but not use current
MetricReporter as you could see the reaon mentioned in FLINK-33695

> When Flink makes a checkpoint, the interaction performance with the external
> file system has a great impact on the overall time-consuming. Therefore, it
> is easy to observe the bottleneck point by adding performance indicators when
> the task interacts with the external file storage system. These include: the
> rate of file write , the latency to write the file, the latency to close the
> file.
> In flink side add the above metrics has the following advantages: convenient
> statistical different task E2E time-consuming; do not need to distinguish the
> type of external storage system, can be unified in the
> FsCheckpointStreamFactory.
