Subject [jira] [Created] (HBASE-5189) Add metrics to keep track of region-splits in RS
Date Fri, 13 Jan 2012 00:55:39 GMT
Add metrics to keep track of region-splits in RS

                 Key: HBASE-5189
                 URL: https://issues.apache.org/jira/browse/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

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)
