-------------------------------------
Summary: HBase read/write metrics not available
Key: AMBARI-25118
URL: https://issues.apache.org/jira/browse/AMBARI-25118
Project: Ambari
Issue Type: Bug
Components: ambari-metrics
Affects Versions: 2.7.1
Reporter: oktay tuncay
Attachments: original widget.PNG, without missing columns.PNG
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.
