About SUSE Manager 4

Now based on SUSE Linux Enterprise 15 Service Pack 1 and the Uyuni project, SUSE Manager 4 further delivers a best-in-class open source infrastructure management solution that lowers costs, enhances availability and reduces complexity.

As a key component of a software-defined infrastructure, SUSE Manager 4 allows our customers to:

Lower costs and simplify management

  • Simplify management and reduce operational expenditure with enhanced package staging through a new Content Lifecycle Management user interface and improved APIs for managing packages, patches, and configurations. Moving packages across multiple stages, like development, QA and production is now a simple UI-based task.

  • Ease virtual machine management with new Salt-based virtual machine management that allows near real-time management of hundreds of servers. This allows managing virtual machines not just through a UI, with start/stop buttons, but also by defining Salt states. For example, you can create a Salt state that always ensures that the same three virtual machines are created and running on all your branch servers. Advanced virtual machine management is a technology preview and will require a paid-for add-on subscription per virtualization host.

Increase availability and visibility with expanded monitoring and alerting capabilities

Gain better infrastructure insights and reduce downtime, with the ability to provision, configure, and automate a reliable and easy to use monitoring and alerting infrastructure built on the next generation Prometheus based monitoring stack. With a single tool, you can now deploy, configure and manage your Linux infrastructure, and also monitor the health of that infrastructure. Monitoring is a paid-for add-on subscription per managed system.

Reduce complexity and regain control

  • SUSE Manager now supports managing openSUSE Leap 15.1 and Ubuntu LTS 16.04 and 18.04 clients.

  • SUSE Manager 4 can be deployed from the unified SUSE Linux Enterprise 15 installer.

  • “Formulas with Forms” capabilities for SAP allow the easy set-up of SAP HANA nodes and HA cluster configuration according to best practices. Formulas are provided as a technology preview via SUSE Package Hub.

Keep Informed

You can stay up-to-date regarding information about SUSE Manager and SUSE products:



SUSE Manager Server 4 is provided through SUSE Customer Center and can be installed with the unified installer for SUSE Linux Enterprise 15 Service Pack 1. It is available for x86-64, POWER (ppc64le), or IBM Z (s390x). No separate SUSE Linux Enterprise subscription is required.

With the adoption of a unified installer in SUSE Linux Enterprise 15, system roles are used to customize the installation for each product. The unified installer provides an easier way to install the operating system and the SUSE Manager Server application together with specific pre-configured system settings. This addresses the need for enterprise deployments to standardize on the base operating system as well as on specific storage setups.

PostgreSQL is the only supported database. Using a remote PostgreSQL database is not supported.

Update from previous versions of SUSE Manager Server

In-place updates from previous versions of SUSE Manager Server are not supported. The supported upgrade method is to migrate the data from your SUSE Manager Server 3.2 installation to SUSE Manager Server 4.0.

If your SUSE Manager Server 3.2 uses an older version of PostgreSQL, you need to upgrade to PostgreSQL 10 before performing the migration!

All connected clients will continue to run and remain unchanged.

For detailed upgrading instructions, see the Upgrade Guide on

Migrating from Red Hat Satellite

Migrating from Red Hat Satellite to SUSE Manager Server 4.0 is conditionally supported. To perform this migration, we strongly recommend you get in contact with a SUSE sales engineer or consultant before starting the migration.

Scaling SUSE Manager

The default configuration of SUSE Manager will scale around one thousand clients, when deployed according to the instructions in the Installation Guide on Scaling beyond that number needs special consideration.

For more information and instructions on large-scale deployments, see

Before you begin, you should always get advice from a SUSE partner, sales engineer, or consultant.

Channels with a large number of packages

Some channels, like SUSE Linux Enterprise Server with Expanded Support or Red Hat Enterprise Linux, come with a very large number of packages that may cause taskomatic to run out of memory. If this occurs, we recommended that you increase the maximum amount of memory allowed for taskomatic by editing /etc/rhn/rhn.conf and adding this line:

You will need to restart taskomatic after this change.

This grants taskomatic up to 4 GB of memory (up from the default of 2GB). If taskomatic continues to run out of memory, you can increase the number further. However, keep in mind that this will affect the total memory required by SUSE Manager Server.

Major changes since SUSE Manager Server 3.2

Prometheus Monitoring

We now include packages for the latest version of Prometheus, as well as self-monitoring capabilities for SUSE Manager. The SUSE Manager Monitoring entitlement is required for all systems that have monitoring with Prometheus enabled.

Prometheus is a monitoring tool that is used to record real-time metrics in a time-series database.

For more information about Prometheus, see Prometheus in the Administration Guide


Exporters convert existing metrics into the format Prometheus requires. We are now providing the following Prometheus Exporters as packages, for SLE12 and SLE15 as well as openSUSE Leap 15.1:

In addition we provide JMX exporter on SUSE Manager Server.

Monitoring is not yet available for other operating system platforms like Red Hat Enterprise Linux or Ubuntu.

Self-monitoring features in SUSE Manager

SUSE Manager provides metrics about its health to Prometheus. Both Server and Proxy can expose metrics. Self-monitoring can be enabled via the Web UI. For that purpose, some Prometheus exporters are pre-installed on SUSE Manager Server and Proxy.

A new formula is also included, to install and manage Node and PostgreSQL exporters on clients managed by Salt. This formula can be configured in the SUSE Manager Web UI.

Content lifecycle management

The content lifecycle management feature allows you to clone software channels through a lifecycle of several environments. You are able to create content projects, select a custom set of software channels as sources, and promote software channels through a pre-defined lifecycle of environments.

You can define filters to exclude specific packages and patches. More filters will be added in a later release.

Once you have selected your sources you can build the selected set which will populate the first environment. After the first environment is built, you can promote it through the environment lifecycle to the next environment in the loop. You can see the status of the build at any time throughout the process.

The result of the build, and the content of every environment, is a channel tree made of cloned software channels of the selected sources, to which systems can be assigned.

Virtualization management for Salt minions

The existing virtualization features have been enhanced for Salt-based systems. This is a technology preview and will require an additional Virtualization Management entitlement. Pricing will be announced soon.

Salt-based virtualization host systems can also create virtual machines using a pre-built disk image.

These features have been added:

  • Deleting virtual machines.

  • Editing virtual machines to add or remove network interfaces or disk, change CPU and memory allocation or the display type.

  • Quick update of the list and state of virtual machines.

  • Displaying virtual machines graphical display in a new tab.

Old Name New Name

























































Please update your bootstrap scripts, bootstrap repositories, and activation keys if any of the packages are part of them.

Base system upgrade

The base system was upgraded to SUSE Linux Enterprise 15 SP1. As a result, all code was ported to run with Python 3 and OpenJDK 11.

Technical preview: Single Sign-On (SSO)

SUSE Manager supports Single Sign-On authentication by implementing the Security Assertion Markup Language (SAML) 2 protocol. Mandatory requirement: an already existing and configured SAML Identity Service Provider (IdP). SUSE Manager must be reconfigured to use the IdP as the source of authentication and post-login mapped users must be already created before enabling SSO.

For more on configuring SSO, see the Authentication Methods chapter in the Administration guide.

Upgrading with SUSE Manager Proxy

SUSE Manager Server 4.0 works with SUSE Manager Proxy 3.2. When upgrading, upgrade the Server first, followed by the Proxies.

For instructions on upgrading with Proxies, see the Upgrade Guide on

Upgrading with inter-server synchronization

When upgrading, upgrade the ISS master first, followed by the ISS slaves.


Supportconfig confidentiality disclaimer

When handling Service Requests, supporters and engineers may ask for the output of the supportconfig tool from SUSE Manager Server or clients.

This disclaimer applies:

Detailed system information and logs are collected and organized in a
manner that helps reduce service request resolution times.
Private system information can be disclosed when using this tool.

If this is a concern, please prune private data from the log files.

Several startup options are available to exclude more sensitive
information. Supportconfig data is used only for diagnostic purposes
and is considered confidential information.

When you run supportconfig on the SUSE Manager Server, the output will contain information about your clients as well as about the Server. In particular, debug data for the subscription matching feature contains a list of registered clients, their installed products, and some minimal hardware information (such as the CPU socket count). It also contains a copy of the subscription data available from the SUSE Customer Center.

If this is a concern, please prune data in the subscription-matcher directory in the spacewalk-debug tarball before sending it to SUSE.

Supportability of embedded software components

All software components embedded into SUSE Manager, like Cobbler for PXE booting, are only supported in the context of SUSE Manager. Stand-alone usage is not supported.

Support for older products

The SUSE Manager engineering team provides 'best effort' support for products past their end-of-life date. For more information about product support, see Product Support Lifecycle.

Support for products that are considered past their end-of-life is limited to assisting you to bring production systems to a supported state. This could be either by migrating to a supported service pack or by upgrading to a supported product version.

Support for Ubuntu Clients

Support for Ubuntu Clients was added in SUSE Manager 3.2. Currently, Salt minions running Ubuntu 16.04 LTS and 18.04 LTS are supported. Support for Ubuntu is limited to specific features. For a detailed list of supported features, see the Client Configuration Guide at


All commands need expertise to operate and can potentially create problems with your installation. The spacewalk-utils package is a packaged set of command line tools. We consider the spacewalk-utils tools valuable enough to be included, but are not able to fully support them.

These spacewalk-utils tools are fully supported:

  • spacewalk-clone-by-date

  • spacewalk-sync-setup

  • spacewalk-manage-channel-lifecycle

All other spacewalk-utils tools are supported at L1 level support only. L1 support is limited to problem determination, which means technical support designed to provide compatibility information, usage support, on-going maintenance, information gathering and basic troubleshooting using available documentation.

Providing feedback

If you encounter a bug in any SUSE product, please report it through your support contact.
