Redis Radar release notes 2026.10.1

Alert descriptions, complete usage exports, and simpler private-registry and air-gapped OpenShift installs.

Redis Radar

Redis Radar 2026.10.1 adds readable alert descriptions and a complete usage export. It also makes installing from a private registry or on an air-gapped OpenShift cluster simpler, and fixes stale indicators and gaps in Redis Cloud discovery.

This is a Short-Term Support (STS) release. See Self-managed releases for more details.

Enhancements

  • Alert descriptions. Redis Software alerts now include a readable description and, where the cluster reports one, the measured value.
  • Complete usage export. The Usage CSV export now includes the retained raw usage fields and nested data. The export redacts sensitive data and protects against spreadsheet formulas.
  • One registry setting for every image. global.imageRegistry now applies to the API server, worker, migration job, and busybox images, as it already did to the bundled PostgreSQL container, so one setting covers every image the chart pulls. The busybox image also gets its own override, dbWaitInitContainer.image.registry, and the helm test pod now receives global.imagePullSecrets.
  • Air-gapped values file. The chart now includes values-airgap.yaml, which lists the images to mirror and the values to set for your registry. On OpenShift, pass it after values-openshift.yaml.
  • Route certificates from a Secret. Set route.tls.externalCertificate.name to a kubernetes.io/tls Secret in the release namespace, so the private key stays out of your Helm values. The chart grants the OpenShift router read access to that Secret unless you set route.grantRouterSecretAccess: false. This requires OpenShift 4.16 or later. It's generally available on 4.19 and later, and a Technology Preview on 4.16 through 4.18.
  • Managed-agent audit records. Radar now records audit events for managed-agent activation decisions, source changes, assignment updates, and failed administrative requests.
  • Polling interval for Redis Software 7.2 and 7.4. app.pollerIntervals.compat sets how often Radar collects from Redis Software 7.2 and 7.4 clusters. The default is 5m. A shorter interval keeps data fresher but adds load to each cluster's management plane.
  • Database queries. Radar skips health reads that aren't needed by Active-Active.
  • Packaged documentation. The documentation packaged with the Helm chart and the RPM has improved image-mirroring and external PostgreSQL setup guidance.
  • Dependencies. Updated backend, frontend, and build dependencies.

Resolved issues

  • Freshness reporting. Cluster and Overview freshness now follows each source's collection interval. Amazon ElastiCache freshness metrics stay consistent across worker replicas.
  • Redis Cloud discovery. Fixed a pagination issue that could make a Redis Cloud Pro subscription with databases appear empty.
  • Redis Cloud API retries. Radar retries a Redis Cloud API read once when it fails with a transient error.
  • Health collection. A slow Redis Software alert request no longer interrupts health collection.
  • Redis Cloud connection fields. The Redis Cloud connection fields are now labeled API account key and API user key.
  • Telemetry settings. The nonfunctional Telemetry settings are removed.
  • OpenShift validation. Helm now rejects Route TLS configurations that can't reach Radar. See Breaking changes.
  • PostgreSQL diagnostics. When schema migration fails because the database login can't SET ROLE, the migration log now includes a hint naming the setting to apply.

Breaking changes

On OpenShift, the chart now accepts only edge termination for the Route. If your values set route.tls.termination to reencrypt or passthrough, or set route.tls.destinationCACertificate, update them before you upgrade. Helm rejects those values.
