  • Kafka configuration drift detection, per-page Kafka metrics, and Schema Registry fixes.

New Features

• [Server] Detect configuration drift on Kafka clusters. Topics, ACLs, schemas, Connect connectors, and cluster settings can each be monitored independently. A change made outside AxonOps raises a critical alert and is recorded in a change history with a full diff. Drift state can be exported and a snapshot taken on demand.
• [Server] Create and delete multiple Kafka ACLs in a single API call.
• [Dash] Add a Config Drift Detection page for Kafka clusters under Settings, listing configuration changes over a selected time range with a per-commit diff. Tracking can be enabled per resource type for topics, ACLs, connectors, schemas, and cluster configuration, and the current cluster state can be downloaded as JSON.
• [Dash] Add Metrics tabs to the Kafka topic, consumer group, Connect cluster, and connector pages, showing the key metrics for the item in context without navigating to the dashboards.
• [Dash] Add a Purge and repopulate RBAC rules action to the Access Control page for SuperUsers, which resets the RBAC engine and rebuilds the cluster and topic relationships. Custom group memberships and user-defined permissions are removed, and confirmation requires typing the organization name.
• [Dash] Add a Delete action for empty consumer groups to the Kafka consumer groups table.
• [Dash] Add a top bar link to the AxonOps Console.
• [Dash] Open the formatted or raw content of a log or event message in a larger dialog from the detail panel, which now fills the available height.

• [Server] Audit events name the resource that was changed and cover Kafka Connect and Schema Registry operations. The resource name is added as a target label on audit alerts.
• [Dash] Group Kafka ACL rules sharing a resource, principal, host, and permission type into a single entry showing every granted operation. Multiple operations can be granted in one submission, and grouped rules are removed in a single request.
• [Dash] Always use AES256 server-side encryption for AWS S3 backup destinations. The option to store backups unencrypted has been removed.
• [Dash] Add All and None shortcuts to the table selector on the backup schedule form and the point-in-time restore page, so every table in a keyspace can be selected or cleared in one action.
• [Dash] Add a Diff column to the Kafka topic partitions table showing the difference between the high and low water marks.
• [Dash] Open the dashboard containing a chart selected from the widget search, expand its row, scroll the chart into view, and highlight it, instead of opening the chart in edit mode.
• [Dash] Update the calendar selection in the date and time picker as a timestamp is typed into the text field.
• [Dash] Show the Enterprise-required notice above the Log Collectors settings form on free subscriptions, where the form was previously disabled without explanation.

Fixes

• [Server] Retain scheduled tasks when the server restarts.
• [Server] Correct the Reporting dashboard templates. Chart legends show descriptive labels, disk throughput charts use SI scaling, and read and write latency charts exclude the Min and Max aggregates. Applied to the Cassandra and DSE templates.
• [Server] Update dependencies to address security vulnerabilities.
• [Dash] Check that a cluster is running a Schema Registry before calling the Schema Registry API, so clusters without one no longer raise error alerts. The Schema Registry and topic pages report a missing, offline, or unreachable registry inline, and topic pages list both the -key and -value subjects.
• [Dash] Submit immediate nodetool runs without the pre-filled cron expression, so they execute once instead of creating a recurring schedule.
• [Dash] Highlight the Alert Definitions sidebar item instead of Active Alerts when viewing alert definitions.
• [Dash] Improvements to security headers, e.g. Strict-Transport-Security, X-Content-Type-Options, Referrer-Policy, Content-Security-Policy. Security improvements around authentication token handling for reports.
• [Dash] Fix logout link on self-hosted deployments.

Release 2026-07-28

  • Kafka transaction monitoring fixes, metrics heartbeat fix, and security updates.

Changes

• [Agent] Restore backups in parallel, using a worker pool to download SSTable files concurrently. The number of workers can be set with restore_parallelism under backup in axon-agent.yml, along with restore_file_timeout, multi_thread_streams, and multi_thread_cutoff_mb.
• [Dash] Set the download parallelism for a restore, and show per-table progress in the restore history. Point-in-time restores list the commit logs replayed on each node.
• [Dash] Link a Kafka topic to its registered schema.

Changes

• [Server] Rename the LOG_FILE and AUDIT_LOG_FILE environment variables to AXON_LOG_FILE and AXON_AUDIT_LOG_FILE. Deployments that set either variable must be updated.
