Primary configuration
The Configuration → Primary configuration tab allows you to configure the general cluster settings.
Available configuration parameters are listed below. Basically, they describe paths to the repositories that are used during the installing process — depending on the cluster operating system (ALT Linux 8, Astra Linux 1.7, or CentOS 7). Only the marked repositories are registered on the cluster servers. For each parameter, you can change the default url to the required one.
You can enable monitoring for the ADPG cluster on the Primary configuration tab. To do this, activate the coresponding checkbox for the Enable monitoring option. See Install monitoring for details.
