  • Replace the requests in the top row with reads and writes #2720. The confusing requests panel was replaced by two panels, one for reads and one for writes. The reads and writes are counted at the coordinator level, which means the number of reads and writes that reached the cluster.

  • Additional information from labels was added when available: Account name and rack. #2734. An improved integration with ScyllaDB Cloud, account name, and rack are now visible in the overview dashboard.
    On-prem users can use those labels by adding them to the target files (similar to how cluster and DC are added).

  • Most of the annotations’ switches and filtering were removed, giving a cleaner look #2710, making the overview easier to understand, a minimal set of filters and annotation switches is now in use.
    This change is only applicable to the overview dashboard; the filters and annotations were not removed from the rest of the dashboards

  • Native histograms GA support #2741 - Native Histograms is an advanced Prometheus feature that is now in GA, to enable it, you would need to enable it on the ScyllaDB side by setting prometheus_allow_protobuf to true.

  • Move the extra labels to a metrics #2441 - This is relevant for Cloud and DataDog Cloud integration. For performance reasons, some of the extra labels: tablets_mode, account_name, account_id, cluster_name, rack, serverExternalId, and serverId will be only on scylla_scylladb_current_version metric.
