Martijn Visser commented on FLINK-30450:
----------------------------------------
With regards to this request, are you looking at FileSource / FileSink (to read
and/or write files) or also looking at this from a checkpoint/savepointing
perspective?
If the first, it would be a duplicate of FLINK-28021 / FLINK-28117 imho.
Exposing the Presto / Hadoop metrics might not be trivial given that these are
loaded via the Flink plugin mechanism
https://nightlies.apache.org/flink/flink-docs-master/docs/deployment/filesystems/plugins/
It would probably require a FLIP and a discussion the Dev mailing list
> FileSystem supports exporting client-side metrics

> Key: FLINK-30450
> URL: https://issues.apache.org/jira/browse/FLINK-30450
> Project: Flink
> Issue Type: New Feature
> Components: FileSystems
> Reporter: Hangxiang Yu
> Priority: Major
>
> Client-side metrics, or job level metrics for filesystem could help us to
> monitor filesystem more precisely.
> Some metrics (like request rate , throughput, latency, retry count, etc) are
> useful to monitor the network or client problem of checkpointing or other
> access cases for a job.
> Some filesystems like s3, s3-presto, gs have supported enabling some metrics,
> these could be exported in the filesystem.
