-------------------------------------
Summary: add region level metrics readReqeustCount and
writeRequestCount
Key: HBASE-7818
URL: https://issues.apache.org/jira/browse/HBASE-7818
Project: HBase
Issue Type: Improvement
Components: metrics
Affects Versions: 0.94.4
Reporter: Tianying Chang
Assignee: Tianying Chang
Priority: Minor
Fix For: 0.94.6
Request rate at region server level can help identify the hot region server.
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.
