[jira] [Commented] (FLINK-33856) Add metrics to monitor the interaction performance between task and external storage system in the process of checkpoint making

Jufang He commented on FLINK-33856:
-----------------------------------

[~pnowojski] It seems reasonable to use TraceReporter to report checkpoint related task-level metrics, could this issue be a subtask of FLIP-384?  WDYT

> 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.
