-------------------------------------
Assignee: Huang Kuan Hao
> Add OM and datanode client call latency metrics in S3 Gateway
> -------------------------------------------------------------
>
> Key: HDDS-17169
> URL: https://issues.apache.org/jira/browse/HDDS-17169
> Project: Apache Ozone
> Issue Type: Improvement
> Components: metrics, s3gateway
> Reporter: Siyao Meng
> Assignee: Huang Kuan Hao
> Priority: Major
>
> S3GatewayMetrics reports latency per S3 API, and XceiverClientMetrics counts
> datanode operations, but S3 Gateway has no latency metrics for the calls it
> makes to OM and datanodes. When an S3 request is slow it is hard to tell
> which backend is responsible.
> Add latency metrics in S3 Gateway, broken down per OM API (e.g. lookupKey,
> listKeys, commitKey) and per datanode operation (e.g. WriteChunk, PutBlock,
> ReadChunk).
