> Add metrics to keep track of region-splits in RS
> ------------------------------------------------

> Key: HBASE-5189

> Project: HBase
> Issue Type: Improvement
> Components: metrics, regionserver
> Affects Versions: 0.90.5, 0.92.0
> Reporter: Mubarak Seyed
> Assignee: Mubarak Seyed
> Priority: Minor
> Labels: noob
> Fix For: 0.94.0

>
> For write-heavy workload with region-size 1 GB, region-split is considerably
> high. We do normally grep the NN log (grep "mkdir*.split" NN.log | sort |
> uniq -c) to get the count.
> I would like to have a counter incremented each time region-split execution
> succeeds and this counter exposed via the metrics stuff in HBase.
> - regionSplitSuccessCount
> - regionSplitFailureCount (will help us to correlate the timestamp range in
> RS logs across all RS)
