Summary: Add Real-time Request Stats Collector
Key: HBASE-29616
URL: https://issues.apache.org/jira/browse/HBASE-29616
Project: HBase
Issue Type: New Feature
Components: monitoring
Reporter: Eungsop Yoo
Assignee: Eungsop Yoo
RegionServers in HBase can sometimes experience abnormally high load, such as
excessive CPU usage or network traffic. Existing methods to diagnose the cause
include (1) using metrics, which are only available at the Region level, (2)
checking recent ResponseTooSlow / ResponseTooLarge logs, which provide only
limited visibility, and (3) employing third-party tools like
[hbase-packet-inspector|https://github.com/kakao/hbase-packet-inspector], which
enable detailed analysis but cannot guarantee complete request tracking and
require external management.
This PR proposes adding a lightweight RequestStatsCollector inside the
RegionServer to capture all requests at the row level in real time. The
collected statistics can be examined and analyzed through the RegionServer web
console.
For more details, please refer to the following document.
