Chris Lohfink updated CASSANDRA-10975:
--------------------------------------
Attachment: 10975-2.2.patch
> Histogram buckets exposed in jmx are sorted by count
> ----------------------------------------------------
>
> Key: CASSANDRA-10975
> URL: https://issues.apache.org/jira/browse/CASSANDRA-10975
> Project: Cassandra
> Issue Type: Bug
> Components: Observability
> Reporter: Chris Lohfink
> Attachments: 10975-2.2.patch
>
>
> The estimated histogram snapshot lets its parent provide the getValues
> implementation which sorts the bucket array:
> https://github.com/dropwizard/metrics/blob/3.1-maintenance/metrics-core/src/main/java/com/codahale/metrics/UniformSnapshot.java#L25
> making it hard to determine what count belonged to what bucket. Along with
> removal of the pre 2.2 deprecated metrics this makes it nearly impossible to
> track latencies over time.
