CIS-Discovery Exam Dumps : Certified Implementation Specialist - Discovery

A horizontal discovery pattern is a set of steps that execute operations to identify, classify, and populate attributes for configuration items (CIs) of a specific category or class, such as infrastructure or application. A horizontal pattern can be applied to any operating system or platform that supports the required protocols and commands12.

Debug mode is a feature of the Pattern Designer that allows you to test and troubleshoot your patterns in real time. To activate Debug mode, you need to have the admin role or a role that includes the pattern_designer_debug permission. Debug mode is not available for users who only have the pattern_designer_read permission1.

Variables are used in discovery patterns to store and manipulate data that is collected or calculated during the discovery process. There are three kinds of variables used in discovery patterns12:

• CI attributes: These are variables that correspond to the attributes of the configuration item (CI) type that the pattern is discovering. For example, name, serial_number, manufacturer, etc. CI attributes are used to populate the CI record in the CMDB with the information gathered by the pattern.
• Temporary: These are variables that are created and used within the pattern, but are not stored in the CMDB. For example, $result, $output, $user_var, etc. Temporary variables are used to store and manipulate data such as the output of a command, the value of a parameter, or the result of a calculation.
• Global: These are variables that are defined in the global scope and can be accessed by any pattern. For example, $mid, $target, $ip_address, etc. Global variables are used to store and access data that is common to all patterns, such as the MID Server, the target device, or the IP address.
