Overview of using rules and images
Monitor rules determine how the data is collected from a monitored Linux or z/VM system. You can add, delete, and change rules. MainView for Linux — Servers searches the rules when the PAS discovers a Linux system to be monitored.
When MainView for Linux — Servers is monitoring a Linux system, the monitored system is called an image. These monitored Linux system names can be many characters. MainView for Linux — Servers requires an image name that is up to eight characters in length. Unique image names let you identify remote Linux systems quickly.
You can add, edit, and delete Linux rules by using the ADLRULER view.
