Description

On Ambari 2.6.x and 2.7.x if the Ambari Metrics Collector whitelisting is enabled, nothing appears in the Grafana HBase - Tables/Users dashboards.

The related metric-patterns are enabled in the whitelist file but it seems that the metrics matching with these patterns are filtered out and not shown on Grafana dashboard.

eg:

regionserver.Tables.*_metric_storeCount
regionserver.Tables.*_metric_storeFileCount
regionserver.Tables.*_metric_storeFileSize
regionserver.Tables.*_metric_tableSize
regionserver.Tables.*_metric_totalRequestCount
regionserver.Tables.*_metric_writeRequestCount
regionserver.Users.*_metric_append_num_ops
regionserver.Users.*_metric_delete_num_ops

To fix this the .p prefix should be ​​added to the above prefixes.
