             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.
