2.2.2. 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

shows staleness and deletions options in the inventory service

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 that reads “Convert system to RHEL” below the system name when looking at your systems.

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.

6.2.2. Conversions

CentOS 7 pre-conversion analysis and conversion experience launched

On June 30, 2024, CentOS Linux 7 will reach End of Life (EOL), requiring users to migrate to a new operating system to continue receiving updates, security patches and new features. As this date rapidly approaches, determining a path for migration and scope will be key as you work to assign resources and meet completion dates. With a recent update to Red Hat Insights, CentOS 7 users can now:

  • Register CentOS Linux 7 systems to display in the Insights inventory list.
  • Start a new pre-conversion task at Automation Toolkit > Tasks > Pre-conversion analysis for converting to RHEL to analyze selected CentOS Linux 7 systems, and receive remediation advice so you can proactively handle issues that could complicate or prevent conversion to RHEL.
  • Run a new conversion task at Automation Toolkit > Tasks > Convert to RHEL from CentOS Linux 7 after you resolve issues identified by the pre-conversion analysis to complete the conversion to RHEL.

You can now check in Satellite-managed hosts with a new –build-packagecache flag for better reporting of installable updates. With the flag set, the host will self-report the list of updates that should be installed based on the content available in the Satellite content view to which that system is subscribed. You can find more information in:

6.2.5. Subscriptions

Support for new Red Hat Enterprise Linux variants in Subscriptions

The subscriptions service now supports reporting for the following Red Hat Enterprise Linux variants on x86:

  • Red Hat Enterprise Linux for SAP
  • Red Hat Enterprise Linux Extended Update Support (EUS) Add-On
  • Red Hat Enterprise Linux High Availability Add-On
  • Red Hat Enterprise Linux Resilient Storage Add-On
  • Red Hat Enterprise Linux Extended Life Cycle Support (ELS) Add-On (On-Demand)

6.2.6. Image Builder

Known issue: Insights image builder fails to build RHEL for Edge images when npm is included

When building RHEL 8 images within Insights image builder, you cannot customize your RHEL for Edge image with the npm package. The NPM package manager expects its configuration to be in the {prefix}/etc/npmrc directory but the npm RPM packages a symlink in the /usr/etc/npmrc directory that links to /etc/npmrc. To work around this problem, include the npm package inside of the OSTree system.

Insights image builder now supports building images for the aarch64 architecture

This enhancement to image builder extends support to the aarch64 architecture, which allows you to select the architecture that you want to build. The compatible target images that you can build for the aarch64 architecture are Amazon Web Service (AWS), Bare Metal, and Guest Images.

Support to build images suitable for Windows Subsystem Linux (WSL)

You can use the Red Hat Insights image builder to create an image suitable for Windows Subsystem Linux (WSL). You can use that image to run a Linux environment directly on your Windows machine. You can use most of the command-line tools, utilities, and applications. The kernel is supplied by Microsoft, and developed on WSL2-Linux-Kernel. This is supported only for the Red Hat Enterprise Linux (RHEL) 8 release. For more information, see Create customized RHEL images for the WSL environment.

6.3. Red Hat Insights for OpenShift

6.3.1. Advisor

Advanced Cluster Manager 2.9 fleet Insights integration

Red Hat Advanced Cluster Manager (ACM) 2.9 has introduced a new overview dashboard, and detailed views that improve navigation, when viewing critical information emitted by OpenShift Container Platform clusters. This revamped experience is similar to the one that Red Hat’s Site Reliability Engineering (SRE) team uses to manage Red Hat clusters.

6.3.2. Cost Management

Security-focused Frequently Asked Questions (FAQ) published

Red Hat Insights cost management service uses its own operator (Cost Management Metrics Operator), to gather and upload data to Red Hat. The data is then processed in its own data pipeline. As a result, there are some differences related to what data is collected, how it is processed and stored. A Frequently Asked Questions (FAQ) article about Cost Management security is available to help answer your questions regarding how the operator handles this data. You can find the FAQ at Cost Management Software as a Service [SAAS]-Security FAQ.

Support for new service account authentication

Project Koku, the upstream of Red Hat Insights cost management, released the Koku Metrics Operator version 3.1.0. This adds support for token-based service authentication, for service accounts in the Hybrid Cloud Console.

Insights expects to release the downstream Cost Management Metrics Operator version 3.1.0 with the upcoming delivery of token-based authentication on the Hybrid Cloud Console.

Chapter 7. October 2023

7.2.3. Advisor

New recommendations added

  • The performance of InterSystems IRIS server may be impacted when Transparent Huge Pages is enabled.
  • Apply hugepages recommendation for better performance of InterSystems IRIS.
  • Apply shmmax recommendation for better performance of InterSystems IRIS.
  • Degraded DNS performance on RHEL 8.5 when Ethernet Controller X710 for 10GbE SFP+ with i40e driver is used.
  • The tuned does not start automatically when the OS boots with graphical target mode.
  • System hangs due to a known kernel bug in the e1000e driver.
  • Application failure occurs when the consumption of file descriptors reaches limit.
  • The chrony service cannot resolve NTP server’s hostnames when it does not have the read permission to the /etc/resolv.conf file.
  • The sendmail service rejects or queues emails when the system load is high.

7.2.4. Vulnerability

Users can now view CVEs without Errata/Advisories that affect their environment

You can now view and assess CVEs that do not have associated Errata/Advisories, but which could still affect your environment. This capability allows your organization to understand its full exposure to CVEs, and to take the necessary steps to mitigate any risks.

For more information about CVEs without Errata/Advisories, refer to this blog article.

7.2.5. Malware Detection

Ability to disable/enable malware signatures

The Malware service now allows you to disable signatures that are not relevant to your environment, in order to reduce noise and to enable you to focus on important and relevant signatures.

This feature enables your organization to make better-informed decisions about where to focus efforts, as the computing footprint grows and the resources managing the infrastructure shrink.

7.3. Red Hat Insights for OpenShift

7.3.1. Advisor

Workload recommendations ready for OpenShift Shared Control Plane

The Advisor service offers recommendations that follow best practices for deploying and running managed OpenShift workloads. These recommendations check for correct limit settings, working with budgets, and implementing best practices that do not harm the underlying cluster.

The October release of the Workload recommendations feature supports Red Hat Hypershift, also known as Red Hat Shared Control Plane on AWS. With this release, the Advisor UI can now show recommendations specific to this flavor of managed OpenShift.

7.3.2. Cost Management

Tag inheritance

A common reporting practice involves tagging every (OpenShift and non-OpenShift) resource that an application uses as application=X, and then requesting a cost report based on application=X from Cost Management.

In some cases, the tags did not propagate through the entire tag hierarchy, or the tags were propagated but not exposed. One example of this issue occurred previously, when OpenShift tags were propagated to PVs and PVCs, but the tags were not available in the Cost Management API. OpenShift now propagates all tags to all levels, and exposes them in the API.

AWS external ID authentication

AWS now supports the use of a unique external ID when creating IAM roles with cross-account access, and suggests using the unique ID as a best practice. You create the role in the Cost Management AWS source flow.

Cost Management now supports external ID. When you create an IAM role, the Integrations wizard flow for Cost Management AWS generates a per-customer randomized string for the external ID in AWS. Copy and paste the string into the External ID field.

img relnotes 102023 create iam role

When a source is created, Sources (Integrations) passes along the external ID and the Amazon Resource Name (ARN) role in a message to Cost Management.

Automatic OpenShift source name

To get per-cluster, per-namespace, and per-tag costs in an OpenShift cluster, install the Cost Management Metrics Operator (CMMO) and configure it to submit data to Red Hat.

The CMMO YAML file contains the Source (integration) name, which identifies the cluster in Cost Management. Previously, configuring the operator instance included manually changing the value of name from the default INSERT-SOURCE-NAME to a custom value. Not changing the value of name from the default value caused confusion, as well as difficult debugging issues.

OpenShift Container Platform (OCP) now automatically generates the OpenShift Source name. if you manually set a Source name, the CMMO uses that name; if not, CMMO automatically generates a Source name based on the clusterID.


You can manually change the auto-generated name.

To disable automatic Source name creation, change the create_source parameter value in the CMMO YAML file to false.

    create_source: false
