Release Notes for Red Hat Insights

Red Hat Insights Documentation Team

Abstract

These release notes highlight the latest features and improvements implemented in the Red Hat Insights application and services.
Red Hat is committed to replacing problematic language in our code, documentation, and web properties. We are beginning with these four terms: master, slave, blacklist, and whitelist. Because of the enormity of this endeavor, these changes will be implemented gradually over several upcoming releases. For more details, see our CTO Chris Wright's message.

Chapter 1. About Red Hat Insights

Red Hat Insights is a Software-as-a-Service (SaaS) application included with almost every subscription to Red Hat Enterprise Linux, Red Hat OpenShift, and Red Hat Ansible Automation Platform.

Powered by predictive analytics, Red Hat Insights gets smarter with every additional piece of intelligence and data. It can automatically discover relevant insights, recommend tailored, proactive, next actions, and even automate tasks. Using Red Hat Insights, customers can benefit from the experience and technical knowledge of Red Hat Certified Engineers, making it easier to identify, prioritize and resolve issues before business operations are affected.

As a SaaS offering, located at Red Hat Hybrid Cloud Console, Red Hat Insights is regularly updated. Regular updates expand the Insights knowledge archive in real time to reflect new IT challenges that can impact the stability of mission-critical systems.

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:

2.2.2. drift

Drift end-of-life

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.

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.

OpenSCAP profile for golden image

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.

Chapter 5. May 2024

5.1. Product-wide updates

5.1.1. Published blogs and resources

5.2. Red Hat Insights for Red Hat Enterprise Linux

5.2.1. General

Insights for Image Mode for RHEL

This update supports the tech preview of Image Mode for RHEL (Red Hat Enterprise Linux). The following new features are now available:

  • Identification and key facts about Image Mode RHEL systems in inventory, including available image updates and rollbacks
  • Image Mode-specific remediations for select recommendations
  • A task that performs a bootc upgrade to update a system to the latest available image
  • Views of which images and hashes are deployed for an account
  • Package-level remediation blocks to support the immutability of Image Mode RHEL

5.2.2. Remediations

Improved user experience when remediating

The Insights remediation service has been updated with a number of user experience improvements, including:

  • A tooltip that explains why you can or cannot execute a playbook. The tooltip appears when you hover over the Execute playbook button on the Remediations page.
  • A compliance scan (insights-client -compliance) is added to the remediation playbook when Compliance issues are present in the playbook.
  • A Connection Status column added under the Systems tab. When you review a specific remediation playbook, the Connection Status indicates the status of your system(s).

5.2.3. Advisor

New recommendations released

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:

5.2.4. Tasks

Notifications are now available for Task events

Tasks users can now receive notifications about the following events: task started, task canceled, task job started, task job completed, and task job failed.

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.

Chapter 6. April 2024

6.1. Product-wide updates

6.1.1. Published blogs and resources

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 in libselinux
  • 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 or qxl 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 party node.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 or rpm fails due to a mismatch of the rpm and rpm-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.

img insights tasks quickstart

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).

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

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 underneath the system name that reads Convert system to RHEL.

shows highlighted note 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.
