Global variables are variables that are automatically available for all steps in horizontal discovery patterns.
They store information about the target CI, such as its IP address, host name, operating system, and credentials. There are two global variables that may be used for steps in horizontal discovery patterns: system and computer_system. The system variable contains the information about the target CI's IP address, host name, and credentials. The computer_system variable contains the information about the target CI's operating system, such as its name, version, and architecture12.
