Chapter 4. Tuning Satellite Server with predefined profiles
If your Satellite deployment includes more than 5000 hosts, you can use predefined tuning profiles to improve performance of Satellite.
Note that you cannot use tuning profiles on Capsules.
You can choose one of the profiles depending on the number of hosts your Satellite manages and available hardware resources.
The tuning profiles are available in the /usr/share/foreman-installer/config/foreman.hiera/tuning/sizes directory.
When you run the satellite-installer command with the --tuning option, deployment configuration settings are applied to Satellite in the following order:
-
The default tuning profile defined in the
/usr/share/foreman-installer/config/foreman.hiera/tuning/common.yamlfile -
The tuning profile that you want to apply to your deployment and is defined in the
/usr/share/foreman-installer/config/foreman.hiera/tuning/sizes/directory -
Optional: If you have configured a
/etc/foreman-installer/custom-hiera.yamlfile, Satellite applies these configuration settings.
Note that the configuration settings that are defined in the /etc/foreman-installer/custom-hiera.yaml file override the configuration settings that are defined in the tuning profiles.
Therefore, before applying a tuning profile, you must compare the configuration settings that are defined in the default tuning profile in /usr/share/foreman-installer/config/foreman.hiera/tuning/common.yaml, the tuning profile that you want to apply and your /etc/foreman-installer/custom-hiera.yaml file, and remove any duplicated configuration from the /etc/foreman-installer/custom-hiera.yaml file.

Procedure
Optional: If you have configured the
custom-hiera.yamlfile on Satellite Server, back up the/etc/foreman-installer/custom-hiera.yamlfile tocustom-hiera.original. You can use the backup file to restore the/etc/foreman-installer/custom-hiera.yamlfile to its original state if it becomes corrupted:# cp /etc/foreman-installer/custom-hiera.yaml \ /etc/foreman-installer/custom-hiera.original
-
Optional: If you have configured the
custom-hiera.yamlfile on Satellite Server, review the definitions of the default tuning profile in/usr/share/foreman-installer/config/foreman.hiera/tuning/common.yamland the tuning profile that you want to apply in/usr/share/foreman-installer/config/foreman.hiera/tuning/sizes/. Compare the configuration entries against the entries in your/etc/foreman-installer/custom-hiera.yamlfile and remove any duplicated configuration settings in your/etc/foreman-installer/custom-hiera.yamlfile. Enter the
satellite-installercommand with the--tuningoption for the profile that you want to apply. For example, to apply the medium tuning profile settings, enter the following command:# satellite-installer --tuning medium
