But it will be good if we can further identify the hot regions on that region server. That way, we can easily find out unbalanced regions problem. > Currently, readRequestCount and writeReqeustCount per region is exposed at webUI. It will be more useful to expose it through hadoop metrics framework and/or JMX, so that people can see the history when the region is hot. > I am exposing the existing readRequestCount/writeRequestCount into the dynamic region level metrics framework. I am not changing/exposing it as rate because our openTSDB is taking the raw data of read/write count, and apply rate function to display the rate already. -- This message is automatically generated by JIRA.
