Description

HBase read/write metrics not available. The root cause is because of 2 columns data are missing.
Read and Write metrics needs following columns data.

Read
regionserver.Server.Get_num_ops._rate + regionserver.Server.ScanNext_num_ops._rate
Write
regionserver.Server.Append_num_ops._rate + regionserver.Server.Delete_num_ops._rate + regionserver.Server.Increment_num_ops._rate+ regionserver.Server.Mutate_num_ops._rate

When I check on the AMS database with the below query, regionserver.Server.ScanNext_num_ops and regionserver.Server.Mutate_num_ops columns are missing!

0: jdbc:phoenix:> select * from METRICS_METADATA_UUID where METRIC_NAME in ('regionserver.Server.Get_num_ops','regionserver.Server.ScanNext_num_ops','regionserver.Server.Append_num_ops','regionserver.Server.Delete_num_ops','regionserver.Server.Increment_num_ops','regionserver.Server.Mutate_num_ops') and app_id='ams-hbase';
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------+

METRIC_NAME APP_ID INSTANCE_ID UUID UNITS TYPE
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------+

regionserver.Server.Append_num_ops ams-hbase [B@64030b91 COUNTER
regionserver.Server.Delete_num_ops ams-hbase [B@383f1975 COUNTER
regionserver.Server.Get_num_ops ams-hbase [B@441cc260 COUNTER
regionserver.Server.Increment_num_ops ams-hbase [B@73a00e09 COUNTER

I have created my own widget without these columns and metrics worked as properly.

I also increase log level for regionserver but I could not cath any error or information.
