Where can I find metrics for HBase in CDH5 flush_avg_time_* missing?

Hi, reading that link:

http://www.cloudera.com/content/cloudera/en/documentation/core/v5-3-x/topics/cm_metrics_hbase.html

 

flush_avg_time_across_regionservers

flush_region_avg_time_across_regionservers

 

these metrics are not CDH5 anymore. Is there any possibility to get timings for these properties? Or they just gone away from HBase?

Re: Where can I find metrics for HBase in CDH5 flush_avg_time_* missing?

This metric seems missing/not-updated in the version of HBase carried in CDH5, which appears to explain why CM does not track it for CDH5 versioned HBase services.

The RSes do have a "FlushTime*" histo-metric in their JMX, but the metric does not ever update per my tests. This seems like a bug that needs to be reported and resolved in upstream HBase.
