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

             Summary: Ambari Metrics whitelisting is failing on * wildcard for Hbase table & user level metrics.
                 Key: AMBARI-25452
                 URL: https://issues.apache.org/jira/browse/AMBARI-25452
             Project: Ambari
          Issue Type: Bug
          Components: ambari-metrics
    Affects Versions: 2.6.0, 2.6.1, 2.6.2
            Reporter: Akash Singh


On Ambari 2.6.x if the Ambari Metrics Collector whitelisting is enabled, Hbase per User and Table level metrics are not getting consider for generation.

It seems that the metrics enabled in the whitelist file as:
{code:java}
regionserver.Tables.*_metric_tableSize
regionserver.Tables.*_metric_totalRequestCount
regionserver.Tables.*_metric_writeRequestCount
regionserver.Users.*_metric_append_num_ops
regionserver.Users.*_metric_delete_num_ops
regionserver.Users.*_metric_get_num_ops
{code}
are filtered out and not shown on Grafana dashboard.

It can be remediated by adding '._p_*' to the whitelist file and restarting the Metrics Collector.e.g.
._p_regionserver.Tables.*_metric_tableSize
