-----------------------------------------------------

                 Key: HBASE-5434
                 URL: https://issues.apache.org/jira/browse/HBASE-5434
             Project: HBase
          Issue Type: Improvement
          Components: metrics, rest
    Affects Versions: 0.94.0
            Reporter: Mubarak Seyed
            Assignee: Mubarak Seyed
            Priority: Minor
             Fix For: 0.94.0


/status/cluster shows only
{code}
stores=2
storefiless=0
storefileSizeMB=0
memstoreSizeMB=0
storefileIndexSizeMB=0
{code}

for a region but master web-ui shows
{code}
stores=1,
storefiles=0,
storefileUncompressedSizeMB=0
storefileSizeMB=0
memstoreSizeMB=0
storefileIndexSizeMB=0
readRequestsCount=0
writeRequestsCount=0
rootIndexSizeKB=0
totalStaticIndexSizeKB=0
totalStaticBloomSizeKB=0
totalCompactingKVs=0
currentCompactedKVs=0
compactionProgressPct=NaN
{code}
In a write-heavy REST gateway based production environment, ops team needs to verify whether write counters are getting incremented per region (they do run /status/cluster on each REST server), we can get the same values from *rpc.metrics.put_num_ops* and *hbase.regionserver.writeRequestsCount* but some home-grown tools needs to parse the output of /status/cluster and updates the dashboard.
