> Key: CASSANDRA-13531
> URL: https://issues.apache.org/jira/browse/CASSANDRA-13531
> Project: Cassandra
> Issue Type: Bug
> Reporter: Marcus Eriksson
> Assignee: Marcus Eriksson
> Fix For: 4.x
>
>
> Patch adds the following metrics;
> * time spent anticompacting data before participating in a consistent repair
> * time spent creating merkle trees
> * time spent syncing data in a repair
> * approximate number of bytes read while creating merkle trees
> * number of partitions read creating merkle trees
> * number of bytes read while doing anticompaction
> * number of bytes where the whole sstable was contained in a repairing range
> so that we only mutated the repair status
> * ratio of how much we anticompact vs how much we could mutate the repair
> status
> * total time spent as a repair coordinator
> * total time spent preparing for repair
