Considering this will be moved from bucket-level to server-level, it's better to add "log" prefix to distinguish with the metric of kv. E.g., logFlushPerSecond and logFlushLatencyMs

It's better to name them kvFlushPerSecond and kvFlushLatencyMs to keep align with the log metrics.

We should remove the void registerMetrics(BucketMetricGroup bucketMetricGroup) of KvTablet, because we don't need to report bucket-level pre-write-buffer metrics.

@zcoo @swuferhong I appended a commit to address above comments, please take a look, especially the metric renaming. |
