Cost management now includes a comprehensive This content is not included.API cheat sheet designed to help users integrate cost data with external platforms. The guide includes API examples and a Bruno (a git-friendly open source tool similar to Postman) collection to simplify the exploration and automation of cost management APIs.
The following are examples of common external platforms:
- Business intelligence platforms such as Power BI, Tableau, and Amazon QuickSight
- Dashboarding platforms such as Grafana
- Billing and chargeback systems
Because cost management is API-first, all functionality that is available through the user interface is also available through the API.
- Sample integrations for Grafana and billing platforms
New sample integrations demonstrate how cost management data can be consumed by external tools.
Three Content from github.com is not included.reference implementations are available for Grafana:
- Grafana Infinity plugin
- Grafana with a Python proxy
- Prometheus-based ingestion and visualization
A Content from github.com is not included.sample integration with Lago demonstrates how to do the following tasks:
- Import cloud and custom cost data
- Generate customer invoices
- Produce itemized billing reports
- Support billing workflows such as credits and adjustments
These integrations complement the existing Content from github.com is not included.PowerBI sample integration.
For more information about these integrations, see the upstream Content from project-koku.github.io is not included.Project Koku.
- Expanded cost management video library
The cost management learning library covers the most common onboarding and operational questions.
There are three new videos:
The following videos were updated:
- Efficiency scores for clusters and namespaces
Cost management now provides efficiency scores at the fleet, cluster, and namespace levels. These scores compare requested resources with actual consumption to help identify opportunities to improve utilization.
Each score includes estimated savings potential, enabling platform teams to prioritize optimization efforts and track improvements over time.
This feature helps organizations promote more efficient resource allocation and reduce infrastructure waste across OpenShift Container Platform environments.
- NVIDIA Multi-Instance GPU (MIG) cost allocation
Cost management now supports NVIDIA Multi-Instance GPU (MIG) environments. MIG technology enables a single physical GPU to be partitioned into multiple isolated GPU instances.

3.2. Red Hat Enterprise Linux updates
Review the April 2026 updates and fixes for Red Hat Lightspeed running on RHEL systems.
3.2.1. General
- Upcoming security improvements and new distribution method for insights-client
With the release of RHEL 10.2 and RHEL 9.8, the distribution method for updates to insights-core is changing. The updates will now be delivered as standard RPM packages in the official Red Hat Enterprise Linux repositories. The insights-client continues to be delivered as an RPM package. As a result of this change, the insights-client will no longer automatically update insights-core during its operation.
A new, tailored SELinux policy will additionally be deployed on systems to ensure that both the insights-client and insights-core operate strictly within a fully defined and confined SELinux security context.
For more information about this update, see the Security improvements and new distribution method for insights-client KB article.
3.2.2. Inventory
- UI fixes and improvements
- Enabled workload filtering in Inventory, allowing users to filter systems running one or more workloads.
- Added buttons on the System Details page for UUIDs.
- Fixed name filtering in the system tag modal. It now applies across all result pages.
- Ensured default and custom staleness and deletion retention settings are applied consistently across all systems.
- Aligned the order of tabs on the System Details page with the main navigation menu.
- Fixed visual issues with the backdrop in the Delete System modal and the Add Systems or Remove System to or from Workspace modals.
- Fixed bulk action availability when selecting systems across all result pages.
- Resolved an issue where the System Details page did not open modals such as Packages, Processes, and others.
- New Inventory experience available in Preview
The Inventory UI has been reworked to align with platform standards and to improve rendering performance. This redesign lays the groundwork for upcoming capabilities such as column management and customizable views.
Users can now try the new experience in pre-production. To enable the Preview mode in the Red Hat Hybrid Cloud Console, use the toggle at the top of the screen. Provide your feedback to help refine the experience further.
3.2.3. Advisor

For more information, read the This content is not included.Red Hat Product Security Risk Report 2025.
3.2.5. Patch / Content
- Build content templates with RHEL extended update support
- Users can now build Content Templates for RHEL EUS, E4S, and EEUS release streams. This extends content management capabilities to legacy environments, enabling tighter control over repositories and packages for systems running versions prior to RHEL 8.
3.2.6. Image Builder
- Build bootable images for image mode RHEL
- You can now use immutable systems by building bootable images for image mode RHEL deployment across the public cloud providers, including Amazon Web Services (AWS), Microsoft Azure, and Google Cloud, as well as on-premise environments using qcow2 and ISO formats. You can explore the image mode deployment model, become familiar with container technologies, and streamline management of image-based RHEL systems.
- Build images with content templates for consistency from build through patching
By combining image blueprints with Content Templates, users now can create a consistent RHEL environment from image build through deployment and ongoing management.
A Content Template defines the repositories and packages that make up your standard operating environment (SOE). Associating a Content Template with an image blueprint ensures repeatable builds of an image by restricting image creation to approved repositories and packages. Systems deployed from those images remain aligned to the same content set.
When updates to the SOE are required, you can update the Content Template, rebuild the image, and apply updates consistently across deployed systems.
For more information about Content Templates, see Managing content templates.
- Build images with AI acceleration drivers and additional add-on software
Image Builder now supports the inclusion of packages and drivers from add-on repositories, enabling users to build RHEL images optimized for AI hardware acceleration without requiring manual post-deployment configuration.
Supported repositories:
- Supplementary
- Extensions
- CodeReady Linux Builder
- High Availability
- SAP Solutions
- SAP NetWeaver
This enhancement streamlines deployment workflows for AI-enabled systems and other specialized workloads.
- UI enhancements for image blueprint creation wizard
- The redesigned image blueprint creation wizard provides improved guidance for image customization with a simplified workflow and fewer navigation steps. Longer, scrollable customization pages help reduce click-next fatigue and improve the overall image creation experience.
3.2.7. Malware Detection

4.2.2. Remediations
- Remediations API scalability and performance updates
- In a single This content is not included.remediations API call, you can add at most 100 issues and 100 distinct systems to a remediation plan.
When you generate a playbook, the API finds issues in more detail and returns errors more consistently.
For more information, see Red Hat Lightspeed Remediations API Change Log.
- Planned remediations in execution readiness
When you create a remediation plan, Red Hat Lightspeed now uses a system of action points to support reliable performance without timeouts or failures. Action points calculate the relative complexity and performance impact of a remediation plan, which can help you decide how and where to execute a remediation plan. Complex issues require a higher number of action points, and simpler issues require a lower number.
Red Hat Lightspeed assigns a specific point value to each type of issue and calculates the plan’s total size against the platform’s performance capabilities.
Issue types use the following action point weights:
- Vulnerability: 20 action points per system
- Advisor: 20 action points per system
- Compliance: 5 action points per system
- Patch: 2 action points per system
- Red Hat Lightspeed supports reliable execution for plans up to 1000 action points and 100 systems.
- Streamlined single-page plan creation
- The multi-step wizard for creating a remediation plan in Red Hat Lightspeed has been replaced by a single-page modal. With the enhanced plan creation experience, you now name your plan, configure auto-reboot settings, and optionally download and view the Ansible Playbook from one screen.
- Multiple resolution selection
- Previously, when you created a remediation plan, if the issue had multiple resolution options, you had to choose an approach to remediate before you created the remediation plan. You can now compare choices and select the best fit after you have created your remediation plan. You find the available remediation options on the Plan details tab of your plan under the Multiple resolutions section.
- UI enhancements and fixes for planned remediations
- The Actions and Systems tabs in a remediation plan have been merged into a new unified Planned Remediations tab, which adds a graphical view of the plan’s systems and action points.
- The new connection troubleshooting modals in the Systems table provide step-by-step CLI and Satellite commands to reconnect hosts based on your subscription type.
- The revised execution confirmation popover presents the confirmation details more clearly.

4.2.4. Content templates (Patch)
- RHEL 10 extension repositories are available in content templates
- You can add the Red Hat Enterprise Linux 10 extensions repository to content templates for patching and image building with those packages. The Red Hat Enterprise Linux 10 extensions repository includes hardware acceleration drivers from partners such as NVIDIA and AMD.
4.2.5. Subscriptions
- New subscriptions notifications for exceeded utilization threshold
Red Hat Lightspeed includes a new Subscriptions service event type that notifies you when subscription usage exceeds defined capacity thresholds. The Exceeded Utilization Threshold event gives proactive visibility into capacity overruns, which helps you identify potential compliance risks and take corrective action before reaching subscription usage limits.
The event integrates with the Hybrid Cloud Console Notifications service and follows the standard event schema. You can use it alongside other Red Hat Lightspeed events for operational monitoring and cost management. You can also forward alerts to external systems such as Splunk, ServiceNow, or Slack. You can also trigger automated workflows such as Event-Driven Ansible.
4.2.6. Image builder
- Blueprint-defined user groups
-
You can define user groups and assign users to them in the blueprint creation wizard. Each group receives a default UID that you can edit. Before this update, you could add users only to default groups, such as
