> Fine-grained observability on a node
> ------------------------------------
>
> Key: CASSANDRA-20581
> URL: https://issues.apache.org/jira/browse/CASSANDRA-20581
> Project: Apache Cassandra
> Issue Type: Task
> Components: Consistency/Repair
> Reporter: Jaydeepkumar Chovatia
> Assignee: Jaydeepkumar Chovatia
> Priority: Normal
>
> The current AutoRepair framework has enough visibility to know which nodes
> are going through repair, the duration they ran repair, the token ranges
> repaired, and the failed ranges.
> However, on a node when repair is running, we miss a few fine-grained
> signals, such as the following:
> # Number of tables/keyspaces/token ranges repaired vs. pending
> # Number of Merkle trees/token-ranges out of sync, which indirectly tells us
> inconsistencies among the nodes
> ## Convert this metric into % of data repaired/not-repaired
>
> Fine-grained node-level observability also came up while
> [reviewing|https://github.com/jaydeepkumar1984/cassandra/pull/54#issuecomment-2813945023]
> the POC for Repair on bootstrap, as it is a must for repairing as part of
> the bootstrap.
> This ticket is to improve the AutoRepair observability, and make it similar
> to _nodetool compactionstats_
