2.2.1. advisor
Recommended guidance for the End of Red Hat Enterprise Linux 6 Extended Lifecycle Support (ELS) period
In light of the official end of the Extended Lifecycle Support (ELS) for RHEL 6, it is strongly recommended that all Red Hat Enterprise Linux 6 systems upgrade to Red Hat Enterprise Linux 7 or Red Hat Enterprise Linux 8. This is necessary to obtain full support. No other recommendations are available for these systems. For more information, see the following:
Issue prevention recommendations
We released 9 new recommendations to prevent issues across various Red Hat Enterprise Linux system components. This includes issues such as firmware, kernel, SSSD, RAID5, in-place upgrade, NIC firmware, and grub2, which can cause system failures, crashes, or other challenges:
- System fails to boot due to the known issue in BIOS
- System boot failure occurs when the grub file is empty or missing
- Kernel crash occurs on the CephFS client due to a known bug in the running kernel
- SSSD enters a failed state
- RAID5 md device hang occurs
- Leapp fails to upgrade RHEL 7 systems to RHEL 8 when the grub is not configured correctly
- Multicast packet amplification
- Grub2 modification requires symbolic link
2.2.2. drift
As of September 30 2024, the drift service, provided in Red Hat Insights for RHEL, will be removed from the product. For more information about the discontinuation of the drift service, contact: Red Hat customer service
2.2.3. Insights image builder
Harness the power of image builder
Image builder has a convenient landing page with an overview, interactive labs, links to documentation, blog posts and videos. Learn how this feature can help you ensure consistent provisioning and deployment across all environments.
Manage images with the blueprints feature
Insights image builder now enables you to alter an image with the blueprints feature. This feature is available in developer preview mode and is displayed in the left sidebar. You can save, edit, and download blueprints to share with colleagues.
First boot scripts feature
The first boot scripts feature is now in full production support mode. For more information, see the following:
2.2.4. inventory
Notifications and integrations events in inventory
The inventory service now triggers New system registered and System deleted events. These occur when a system is newly registered in inventory or removed. These events are triggered both manually and automatically. You can manually trigger these alerts when you add a new system to your inventory. Events might be automatically triggered when a system’s state changes.
For more information about system states and staleness and deletion, see the following:
You can configure responses to these events for each account. You can send emails to groups of users, if they allow subscriptions in their user preferences. You can also forward these events to third-party applications such as Splunk, ServiceNow, Event-Driven Ansible, Slack, Microsoft Teams, and Google Chat. You can also forward these events by using a generic webhook. For more information, see the following resources:
These new events are particularly useful for driving automation and integrating Red Hat Insights into your operational workflows. They can automatically launch compliance or malware detection checks, validate systems assignments to Workspaces, update external configuration management database (CMDB) records, or continuously monitor your Red Hat Enterprise Linux environment.

New recommendations released
We released 8 new Advisor recommendations in July for Red Hat Enterprise Linux system administrators:
3.3. Red Hat OpenShift Container Platform
3.3.1. Advisor
New integration
The Insights advisor service is now fully integrated into Advanced Cluster Manager. Insights detects issues and provides remediations recommendations.
3.3.2. Cost Management
Attribute Azure node attached storage to OpenShift projects
This feature allows Red Hat to better report and distribute OpenShift storage costs. This is especially applicable to running OpenShift on Azure. Enhancements for AWS and GCP will follow soon.
Cluster/Node networking costs for OpenShift in the cloud
A new project, Network Unattributed, has been created to clarify your networking costs. Costs associated with ingress and egress network traffic are now itemized. This applies to individual AWS, Azure and GCP nodes.

4.2. Red Hat Insights for Red Hat Enterprise Linux
4.2.1. Advisor
New recommendations released
Two more CrowdStrike recommendations were added for smoother operations of the Falcon sensor:
Brand new IBM DB2 recommendations specifically focused on SAP environments were also added:
4.2.2. Image builder
Insights image builder has a new landing page
A new Knowledge Article on the Customer Portal, Learn about Red Hat Enterprise Linux and Insights image builder, now serves as a public-facing landing page. This page provides a convenient overview of Insights image builder, and provides a comprehensive list of the latest blogs and videos about Image builder.
Blueprints
Blueprints make it easier for you to manage your RHEL images. Images expire after two weeks, but blueprints last forever. Create a blueprint for your golden image, modify it over time as your needs change, and use it to build and deploy images on demand.
Users will notice a new announcement banner linking to a Getting Started quick-start guide. This capability was initially available in the on-premises RHEL image builder and is now available as part of the Insights experience. Future development will include the ability to import and export blueprint files.
Build security-hardened images
You can now apply Security Compliance benchmark policies, as provided from the trusted OpenSCAP tools, to your customized RHEL golden images for any target environment - complete with guided file system configurations! This ensures that security hardening changes are applied during image creation so that when launched, systems are more secure before they ever initialize CPU or memory, or even connect to a network.
This change makes it extremely easy for highly secure environments to meet their security compliance requirements. It also enables users who do not have deep security knowledge to achieve better security by default.
First-boot-script configuration
Provided as a Technology Preview, Insights image builder has added the first-boot-script configuration feature to embed scripts in the image that are run when an instance first starts up. This feature enables you to run your scripts to do any variety of custom tasks that you may require. Tasks could include shell or python scripts, as well as Ansible playbooks. Future blog posts will provide simple examples to help users use this feature quickly and easily.
4.3. OpenShift Container Platform
4.3.1. Cost Management
Resource Optimization for OpenShift GA
After a year in preview, Red Hat announced the general availability of the resource optimization service for OpenShift Cost Management.
View announcements about the release:
AWS Savings Plans enabled by default
Cost Management has supported AWS Savings Plans for years. However, users had to manually select the AWS Amortized cost view in the Settings page, or in each of the cost pages, leading to support cases due to customers seeing an unexpected cost (caused by looking at the incorrect view mode in Cost Management).
Cost Management now detects whether savings plans are in use in AWS accounts, and automatically shows data including the discounts from the savings plans in all cases. Configuring the Amortized view is no longer needed.

We have partnered with IBM to deliver a recommendation that optimizes IBM DB2 in SAP environments, in keeping with IBM best practices.
In total, 7 new recommendations were added in May:
- LVM-activate resource will fail to start on this node because the required volume group is not visible on it
-
Reboot fails with
grub
prompt when missing required GRUB2 modules on systems - IBM DB2 will not perform optimally in SAP environment when not configured per IBM best practices
-
The
sudo
access fails for AD users or groups when using FQDN name insudoers
file - GRUB is no longer maintained and does not receive updates and GRUB2 is recommended to use for RHEL 7
- Red Hat will not provide technical support services after RHEL 6 ELS ends and recommends upgrading to RHEL 7 or RHEL 8
-
System fails to boot when NICs with
ice
driver are configured as bonding devices
5.2.4. Tasks

You can use these events with Insights native integrations for Microsoft Teams, Google Chat, Slack, ServiceNow, Splunk, and Event-Driven Ansible.
5.2.5. Image builder
Insights image builder repository recommendations
Insights image builder can now help find packages that are not available in the currently selected repositories. If a package is not found in the currently selected repositories, image builder provides an option to Search other repositories. This option searches for the package in repositories you have already configured, as well as other popular repositories.
5.3. OpenShift Container Platform
5.3.1. Advisor
Update risks multi-cluster experience
This update to Insights Advisor for OCP includes easy-to-identify Update risk labels, which allow you to immediately spot clusters that face update blocking problems.
5.3.2. Vulnerability dashboard
Image details now added to the Vulnerability Dashboard
Before this update, you could only view affected clusters in your environment for the CVEs affecting your infrastructure. The dashboard did not show affected images. With this release, you can now view container images affected by the vulnerabilities in your OCP environment.
Chapter 6. April 2024

6.2. Red Hat Insights for Red Hat Enterprise Linux
6.2.1. Remote host configuration (rhc) and the Insights client
Upcoming End of Life for Basic Authentication mechanism for Insights client
Effective December 30th, 2024, the Insights client will no longer support Basic Authentication as an option for connecting a host with Red Hat Insights.
Basic Authentication is not the default authentication mechanism, but it has been available as a manually configured option for a select set of workflows. Red Hat recommends that you modify host systems using Basic Authentication to instead use certificate authentication. Otherwise, the systems will not be able to connect to Insights after the end of December 2024.
For more information, see the following KCS article: How to switch from Basic Auth to Certificate Authentication for Red Hat Insights and the Red Hat Insights Life Cycle page.
6.2.2. Inventory
Hosted RHSM accounts in SCA mode are now pointed to Inventory
Accounts using Simple Content Access (SCA) mode and hosted RHSM for inventory management have now been migrated from access.redhat.com to https://console.redhat.com/insights/inventory.
For more information, see the following article: Transitioning Red Hat Subscription Management to the Hybrid Cloud Console.
6.2.3. Remediations
Validation of duplicate or blank remediation names
Insights now validates new playbooks created using the Remediate with Ansible option. The validation process prevents the creation of any playbooks that contain blank values, or that contain values that already exist in playbooks in the same account.
6.2.4. Advisor
CrowdStrike recommendations
Red Hat has partnered with CrowdStrike to co-develop a new set of Insights Advisor recommendations. The first recommendation, The Falcon sensor is in Reduced Functionality Mode (RFM) when it is set to kernel mode and does not support the current kernel was released in late April.
New recommendations released
Nine new recommendations were added in April:
-
Kernel panic occurs when accessing data on a gfs2 filesystem when it is mounted with
quota=on
option -
cron
jobs failed due to a known bug inlibselinux
- The system is unable to boot in GUI due to incorrect ownership on GNOME files or directories
- AD users fail to log in due to a known issue in SSSD
-
Virtual Machines fail to be created or started when using
spice
orqxl
in VM XML after upgrading to RHEL 9 -
System crash occurs when executing
kpartx
command on dm-multipath device due to a known bug -
The
leapp
upgrade fails when a third partynode.js
package is installed on RHEL 7 - D-Bus service fails to run when the machine-id file does not exist or does not have the correct permissions
-
Package installation and update with
yum
orrpm
fails due to a mismatch of therpm
andrpm-plugin-selinux
6.2.5. Tasks
Quick Starts now available to help with getting started
The Red Hat Insights UI now contains a Quick start for each of the available Tasks. Quick starts offer in-app guidance to help you prepare for and run a Task. To launch a Quick start, click the Help me get started link within a Task section.
6.2.6. Image Builder
Insights Images now creates ISO images with osbuild.ks
Previously, users manually added the fleet.ks
kickstart to the ISO to enable a non-interactive installation. With this update, the osbuild.ks
file is now automatically injected into the ISO images that are created from Insights images during image building. Consequently, users no longer need to customize the image to enable non-interactive installation
6.3. OpenShift Container Platform
6.3.1. Cost Management
Tag reconciliation
Insights cost management reads labels from OpenShift and tags from AWS, Azure, Google Cloud, and Oracle Cloud, and makes all of them available as a unified list.
Since an arbitrary number of OpenShift clusters and cloud accounts can be added to one Cost Management account (Red Hat organization), and because tag/label naming conventions can be inconsistent or can change over time, situations can arise where multiple tags represent one concept requiring users to perform complex manual post-processing.
The Cost Management Settings page now allows you to define tag maps to combine multiple imported tags into one, simplifying cost aggregation and reports and removing the need for manual post-processing.
Tag reconciliation also enables Insights to perform cost distribution based on tags, in addition to the existing features that cost models currently support.
Cluster information page
Sometimes cloud and/or OpenShift costs reported by Insights cost management do not match the user view in the cloud provider console. This discrepancy is not due to a bug in cost management but can occur for the following reasons:
- a lack of OpenShift or cloud billing data
- a missing integration between the Hybrid Cloud Console and either the OpenShift cluster(s), or the AWS, Azure, Google Cloud and/or Oracle Cloud customer accounts
Both conditions can cause missing billing and/or cluster data in Insights cost management, which in turn leads to the cost discrepancy.
To make this condition easier for users to diagnose, two new views have been added in the cluster breakdown section of the limit=10&filter[offset]=0&group_by[cluster]=*[OpenShift details page]:
- The Cluster information view offers essential cluster information, such as the cluster UUID, Cost Management Metrics Operator version, and links to integrations. This view also provides additional information about when to update the Cost Management Metrics Operator version.
- The Data details view offers insights into data processing, helping users track data flows through Cost Management. This view provides visibility into which OpenShift and cloud data was processed, and when it was processed.
Excel and Power BI sample reports
Red Hat Insights cost management provides powerful dashboards and reports, with export capabilities both in the web UI (to CSV) and through the API (JSON and CSV).
You can use an external business intelligence (BI) tool to combine data and insights with your business information. This approach can help you to answer questions such as the following:
- Does the nightly batch job that processes POS transactions cost more because more transactions are being processed (because business is growing), or is it because the last release of the application consumes more resources?
- Is my total spending trend following/predicting my business?
- Is my total cluster capacity growing according to the same trend as my business?
- Are my development teams getting better in terms of resource utilization (that is, are recommendation values converting to current values)?
- Is capacity converting to recommendations?
Microsoft Excel and Microsoft Power BI are the most popular BI tools. Both tools read data from the Cost Management API. Sample reports in Microsoft Excel and MIcrosoft Power BI formats are now available for free from the following repository: https://github.com/project-koku/cost-mgmt-powerbi-sample
These sample reports achieve the following goals:
- Show good practices (for example, not requesting all of the desired data at the same time).
- Show familiar data. The Insights web UI is embedded within the Excel and Power BI sample reports, so that you see which API endpoints to use and how to use them in your custom reports.
- Produce self-contained reporting, even at the cost of suboptimal decisions (which are clearly documented in the sample reports). For example, the Excel sample stores the credentials in a CSV file (whereas the recommended procedure uses a vault), and the Power BI sample uses Excel as storage (whereas Power BI normally uses a database, such as Microsoft SQL Server or Azure SQL).

New Advisor Recommendations
Nine new recommendations are available:
- The Hyper-V guest running with "hv_storvsc" driver partially hangs or the system crashes when memory exhaustion occurs on the Hyper-V host
- Kernel panic occurs when accessing data on a gfs2 filesystem when it is mounted with "quota=on" option
- Cron jobs failed due to a known bug in libselinux
- The x86-64-v1 and x86-64-v2 microarchitecture level of CPU will be marked deprecated in RHEL 8 and RHEL 9
- The autofs process crashes when multiple processes access the same autofs path at the same time
- Authentication failure occurs with AD user when unwanted files are included
- Leapp crashes when there are too many filesystems running on LVM devices
- Conversion to RHEL will fail with running convert2rhel when the plymouth package is not installed
- IO operations on MD RAID 5 array stuck during heavy IO load due to a regression kernel bug
7.2.2. Inventory
Custom Staleness and Deletion
System administrators can use Custom Staleness and Deletion settings to configure the number of days systems need to be inactive, before Red Hat Insights considers the systems to be stale and flags them for removal from your inventory.
By default, when a system does not communicate with Red Hat within one day, the system is labeled as stale. If the system does not communicate within 7 days, it is labeled as stale warning. If the system does not communicate within 14 days, Insights removes it from the inventory. With this feature update, your system administrators can change settings for:
- system staleness up to 7 days
- system stale warning up to 180 days
- system deletion up to 2 years
The feature is now available in Inventory > System Configuration > Staleness and Deletion.
For more information about roles and permissions needed to manage system staleness and deletion, see Managing system staleness and deletion with Red Hat Insights for Red Hat Enterprise Linux in Viewing and managing system inventory.
Identifying CentOS hosts that are compatible for pre-conversion and conversions
When viewing hosts within the Insights inventory, if a CentOS 7 host is registered to Insights and compatible to run a Pre-Conversion analysis or Conversion task, you will see a visual indicator underneath the system name that reads Convert system to RHEL.
7.3. OpenShift Container Platform
7.3.1. Advisor
Insights Advisor for Workloads available in preview
A preview version of Insights Advisor for Workloads application is available. Insights Advisor for Workloads uses Deployment Validation Operator (DVO) to provide recommendations on best practices and security policies around deployments of workloads. The application helps avoid issues such as misconfigured workloads, which can cause the platform to suffer from memory or CPU overcommitment, resulting in critical cluster issues.
To test the preview version of the new application, see Red Hat Hybrid Cloud Console > RHEL > Insights > Advisor > Workloads
Deployment Validation Operator (DVO) available to on-premise clusters
DVO, formerly available only to Red Hat Managed offerings, is now generally available. The operator serves as an in-cluster workload configuration evaluation tool. Using Red Hat Insights, the tool reports misconfigurations of workloads to Red Hat.
You can access and install the tool from the Red Hat ecosystem catalog.
