System Groups

The System Groups page allows Uyuni users to view the System Groups list.

systems systemgroups

Only System Group Administrators and Uyuni Administrators have permission to perform these additional tasks:

  • Create system groups

  • Add systems to system groups

  • Remove systems from system groups

  • Assign system group permissions to users

For more information about system groups, see reference:systems/system-details/sd-groups.adoc. For more information about configuring system groups, see reference:users/system-group-configuration.adoc.

The System Groups list displays all system groups. The list contains several columns for each group:

  • Select — Via the check boxes add all systems in the selected groups to the System Set Manager by clicking the Update button. All systems in the selected groups are added to the System Set Manager. You can then use the System Set Manager to perform actions on them simultaneously. It is possible to select only those systems that are members of all of the selected groups, excluding those systems that belong only to one or some of the selected groups. To do so, select the relevant groups and click the Work with Intersection button. To add all systems of all selected groups, click the Work with Union button. Each system will show up once, regardless of the number of groups to which it belongs.

  • Updates — Shows which type of patch alerts are applicable to the group or confirms that all systems are up-to-date. Clicking a group’s status icon takes you to the Patch tab of its System Group Details page.

    The status icons call for differing degrees of attention:

    • Check Circle — All systems in the group are up-to-date.

    • Exclamation Circle — Critical patches available, update strongly recommended.

    • Warning — Updates available and recommended.

  • Health Status of the systems in the group, reported by probes.

  • Group Name — The name of the group as configured during its creation. The name should be explicit enough to distinguish from other groups. Clicking the name of a group takes you to the Details tab of its System Group Details page.

  • Systems — Total number of systems in the group. Clicking the number takes you to the Systems tab of the System Group Details page for the group.

  • Use in SSM — Clicking the Use in SSM link in this column loads all and only the systems in the selected group and launches the System Set Manager immediately.

Adding and Removing Systems in Groups

Systems can be added and removed from system groups. Clicking the group name takes you to the Details page. The Systems tab shows all systems in the group and allows you to select some or all systems for deletion. Click Remove Systems to remove the selected systems from the group. The Target Systems page shows you all systems that can be added to the group. Select the systems and click the Add Systems button.

System Group Details

At the top of each System Group Details page are two links: Delete Group and Work With Group. Clicking Delete Group deletes the System Group and should be used with caution. Clicking Work With Group loads the group’s systems and launches the System Set Manager immediately like the Use Group button from the System Groups list. For more on the System Set Manager, see reference:systems/ssm-overview.adoc.

The System Group Details page is split into the following tabs:

Group Details

Provides the group name and group description. To change this information, click Edit These Properties, make your changes in the appropriate fields, and click the Update Group button.

Systems

Lists all members of the system group. Clicking links within the table takes you to corresponding tabs within the System Details page for the associated system. To remove systems from the group, select the appropriate check boxes and click the Remove Systems button on the bottom of the page. Clicking it does not delete systems from Uyuni entirely. This is done through the System Set Manager or System Details pages.

For more on the System Set Manager, see reference:systems/ssm-overview.adoc. For more on system details, see reference:systems/system-details.adoc.

Target Systems

Target Systems — Lists all systems in your organization. To add systems to the specified system group, click the check boxes to their left and click the Add Systems button on the bottom right-hand corner of the page.

Patches

List of relevant patches for systems in the system group. Clicking the advisory takes you to the Details tab of the Patch Details page. For more on patches, see reference:patches/patch-details.adoc. Clicking the Affected Systems number lists all of the systems affected by the patch. To apply the patch updates in this list, select the systems and click the Apply Patches button.

Admins

List of all organization users that have permission to manage the system group. Uyuni Administrators are clearly identified. System Group Administrators are marked with an asterisk ('*'). To change the system group’s users, select and deselect the appropriate check boxes and click the Update button.

States

The States tab displays states which have been created and added using the Salt  State Catalog. From this page you can select which states should be applied across a group of systems. A state applied from this page will be applied to all clients within a group.

States are applied according to the following order of hierarchy within Uyuni:

Organization > Group > Single System
Procedure: Applying States at the Group Level
  1. Create a state using the Salt  State Catalog or via the command line.

  2. Browse to Main Menu  Systems  System Groups. Select the group that a new state should be applied to. From a specific group page select the States tab.

  3. Use the search feature to located a state by name or click the Search button to list all available states.

  4. Select the check box for the state to be applied and click the Save button. The Save button will save the change to the database but will not apply the state.

  5. Apply the state by clicking the Apply button. The state will be scheduled and applied to any systems included within a group.
