Chapter 1. Reviewing hosts in Satellite web UI
You can review hosts in the Satellite web UI to see them in one place and select the columns you need for daily work. When Red Hat Enterprise Linux lifecycle data is available, check it in the same views to plan patches and track compliance.
1.1. Browsing hosts in Satellite web UI Copia collegamentoCollegamento copiato negli appunti!
In the Satellite web UI, you can browse all hosts recognized by Satellite, grouped by type.
The following host types are available when browsing hosts in the Satellite web UI:
- All Hosts – a list of all hosts recognized by Satellite.
- Discovered Hosts – a list of bare-metal hosts detected on the provisioning network by the Discovery plugin.
- Host Collections – a list of user-defined collections of hosts used for bulk actions such as errata installation.
Procedure
Search for a host: Type in the Search field, and use an asterisk (*) to perform a partial string search. For example, if searching for a host named
server.example.com, click the All Hosts page and typeserver*in the Search field. Alternatively,*ver*will also find the hostserver.example.com.WarningSatellite Server is listed as a host itself even if it is not self-registered. Do not delete Satellite Server from the list of hosts.
- Navigate between hosts: Click ⇄ next to the hostname. This displays a list of hosts in alphabetical order with a pagination arrow and a search bar to find the host you are looking for.
1.2. Selecting host columns Copia collegamentoCollegamento copiato negli appunti!
You can select what columns you want to see in the host table on the Hosts > All Hosts page.
It is not possible to deselect the Name column. The Name column serves as a primary identification method of the host.
Procedure
- In the Satellite web UI, navigate to Hosts > All Hosts.
- Click Manage columns.
Select columns that you want to display. You can select individual columns or column categories. Selecting or deselecting a category selects or deselects all columns in that category.
NoteSome columns are included in more than one category, but you can display a column of a specific type only once. By selecting or deselecting a specific column, you select or deselect all instances of that column.
Verification
- You can now see the selected columns in the host table.
1.3. Lifecycle status of RHEL hosts Copia collegamentoCollegamento copiato negli appunti!
With Satellite, you can monitor the lifecycle status of your hosts by displaying upcoming End of Support (EOS) events. This is useful so that you can quickly identify which hosts require an update or action to maintain support.
Satellite provides multiple mechanisms to display information about upcoming EOS events for your Red Hat Enterprise Linux hosts:
- Notification banner
- A column on the Hosts index page
- Alert on the Hosts index page for each host that runs Red Hat Enterprise Linux with an upcoming EOS event in a year as well as when support has ended
- Ability to Search for hosts by EOS on the Hosts index page
- Host status card on the host details page
For any hosts that are not running Red Hat Enterprise Linux, Satellite displays Unknown in the RHEL Lifecycle status and Last report columns.
When either the end of maintenance support or the end of extended lifecycle support approaches in a year, you will see a notification banner in the Satellite web UI if you have hosts with that Red Hat Enterprise Linux version. The notification provides information about the Red Hat Enterprise Linux version, the number of hosts running that version in your environment, the lifecycle support, and the expiration date. Along with other information, the Red Hat Enterprise Linux lifecycle column is visible in the notification.
1.4. Displaying RHEL lifecycle status Copia collegamentoCollegamento copiato negli appunti!
You can display the status of the end of support (EOS) for your Red Hat Enterprise Linux hosts in the table on the Hosts index page.
Procedure
- In the Satellite web UI, navigate to Hosts > All Hosts.
- Click Manage columns.
- Select the Content column to expand it.
- Select RHEL Lifecycle status.
- Click Save to generate a new column that displays the Red Hat Enterprise Linux lifecycle status.
Optional: You can use the Search field to search hosts by
rhel_lifecycle_status. It can have one of the following values:-
full_support -
maintenance_support -
approaching_end_of_maintenance -
extended_support -
approaching_end_of_support -
support_ended
-
1.5. Host global status overview Copia collegamentoCollegamento copiato negli appunti!
You can use the host global status in Satellite to see at a glance whether a host is OK, needs attention (Warning), or has errors. The status appears on the Hosts Overview page and helps you prioritize which hosts to investigate.
The host global status can have one of three possible values: OK, Warning, or Error. You can find global status on the Hosts Overview page. The status displays a small icon next to the host name and has a color that corresponds with the status. Hovering over the icon renders a tooltip with sub-status information to quickly find out more details. To view the global status for a host, in the Satellite web UI, navigate to Hosts > All Hosts.
- OK
- No errors were reported by any sub-status. This status is highlighted with the color green.
- Warning
- While no error was detected, some sub-status raised a warning. For example, there are no configuration management reports for the host even though the host is configured to send reports. It is a good practice to investigate any warnings to ensure that your deployment remains healthy. This status is highlighted with the color yellow.
- Error
- Some sub-status reports a failure. For example, a run contains some failed resources. This status is highlighted with the color red.
If you want to search for hosts according to their status, use the syntax for searching in Satellite that is outlined in the Searching and Bookmarking in Administering Red Hat Satellite, and then build your searches out by using the following status-related examples:
To search for hosts that have an OK status:
global_status = ok
To search for all hosts that deserve attention:
global_status = error or global_status = warning
1.6. Host sub-status overview Copia collegamentoCollegamento copiato negli appunti!
You can use host sub-statuses in Satellite to see the status of specific areas of a host, such as configuration, build, or content. Sub-statuses feed into the global host status and help you pinpoint what needs attention.
To view the sub-statuses of a host, in the Satellite web UI, navigate to Hosts > All Hosts and click on the host whose full status you want to inspect. You can view the global host status next to the name of the host and the host sub-statuses on the Host status card.
Each sub-status has its own set of possible values that are mapped to the three global status values. With any change of a sub-status, the global status is recalculated and the result is determined by the statuses of all sub-statuses.
The following sub-statuses are available in Satellite:
- Configuration
This sub-status is only relevant if Satellite uses a configuration management system like Ansible, Puppet, or Salt.
Possible values:
Expand Label Global host status Alerts disabled
OK
Active
OK
Pending
OK
No changes
OK
No reports
OK / Warning
Out of sync
Warning
Error
Error
Additional information about the values of this sub-status:
- Active: During the last configuration, some resources were applied.
-
Pending: During the last configuration, some resources would be applied but your configuration management integration was configured to run in
noopmode. - No changes: During the last configuration, nothing changed.
-
No reports: This can be both a Warning or OK status. When there are no reports but the host uses an associated Capsule for configuration management or the
always_show_configuration_statussetting is set totrue, it maps to Warning. Otherwise it maps to OK. - Error: This indicates an error during configuration. For example, a configuration run failed to install a package.
-
Out of sync: A configuration report was not received within the expected interval, based on the
outofsync_intervalsetting. Reports are identified by an origin and can have different intervals based upon it.
- Build
This sub-status is only relevant for hosts provisioned from Satellite or hosts registered through global registration.
Possible values:
Expand Label Global host status Number value Installed

If you want to search for hosts according to their sub-status, use the syntax for searching in Satellite that is outlined in the Searching and Bookmarking chapter of the Administering Satellite guide, and then build your searches out by using the following status-related examples:
You search for hosts' configuration sub-statuses based on their last reported state.
For example, to find hosts that have at least one pending resource:
status.pending > 0
To find hosts that restarted some service during last run:
status.restarted > 0
To find hosts that have an interesting last run that might indicate something has happened:
status.interesting = true
