--------------------------------
Summary: HBase Canary region success count metrics reflect column
family successes, not region successes
Key: HBASE-23172
URL: https://issues.apache.org/jira/browse/HBASE-23172
Project: HBase
Issue Type: Improvement
Components: canary
Affects Versions: 2.2.1, 2.1.5, 2.0.0, 1.5.0, 1.4.0, 1.3.0, 3.0.0
Reporter: Caroline
Assignee: Caroline
HBase Canary reads once per column family per region. The current "region
success count" should actually be "column family success count," which means we
need another metric that actually reflects region success count. Additionally,
the region read and write latencies only store the latencies of the last column
family of the region read. Instead of a map of regions to a single latency
value and success value, we should map each region to a list of such values.
