--------------------------------------
Summary: Add offline/online region count into metrics
Key: HBASE-20943
URL: https://issues.apache.org/jira/browse/HBASE-20943
Project: HBase
Issue Type: Improvement
Components: metrics
Affects Versions: 1.2.6.1, 2.0.0
Reporter: Tianying Chang
We intensively use metrics to monitor the health of our HBase production
cluster. We have seen some regions of a table stuck and cannot be brought
online due to AWS issue which cause some log file corrupted. It will be good if
we can catch this early. Although WebUI has this information, it is not useful
for automated monitoring. By adding this metric, we can easily monitor them
with our monitoring system.
