If you click the Systems link on the left navigation bar, the Systems Overview page appears. The pages in the System category allow you to select systems so that you can perform actions on them and create system profiles.
As shown in Figure 6-3, the System List page displays a list of all your registered systems.
The System List contains several columns for each registered system:

Alerts — Shows which type of Errata Alerts are applicable to the system:
— Critical errata available, update

— Updates available and recommended

— System is up-to-date
Errata — Total number of Errata Alerts applicable to the system.
Pkgs — Total number of package updates for the system. Includes packages from Errata Alerts as well as newer packages that are not from Errata Alerts. For example, if a system is subscribed to the Red Hat Linux 7.1 i386 channel that contains version 2.5.4 of a package because that is the version that shipped with Red Hat Linux 7.1, but the system has version 2.5.2 of the package installed, the newer version of the package will be in the list of updated packages for the system.
