There are two color indicators of system status in the section of the control panel:
The upper indicator shows the status of system updates. If it is green, the system is up to date and no action is necessary. If updates are available for installation, the indicator turns red and the button is shown.
To install all available updates, use the button. Alternatively, click the link showing information about the updates to start the WebYaST module. With this module, you can see the list of available updates and choose which updates to install. For more information about the module, see Section 4.2, “Managing System Updates”.
The bottom indicator shows the health of the system. If it is green, the system is healthy. The health information is determined by data from the module and the user-defined limits set there. For more information about the module, see Section 4.3, “Monitoring System Status”.
