CIS-Discovery Exam Dumps : Certified Implementation Specialist - Discovery

 The functionality shown in the image is related to the Tracked Configuration files feature of ServiceNow Discovery. This feature allows Discovery to track changes in configuration files on Windows and Unix hosts and store them as configuration items (CIs) in the CMDB1. To modify this functionality, such as adding or removing files to track, changing the file attributes to capture, or defining the CI relationships, one needs to edit the Discovery Pattern that is associated with the Tracked Configuration files classifier2. A Discovery Patternis a series of operations that tell Discovery how to find and identify an application or a configuration file on a host3.

The Pattern Designer is a graphical tool that allows users to create and edit horizontal discovery patterns. The Pattern Designer has three main sections: the left section shows the CI type and the pattern type, the middle section shows the pattern steps and the flow diagram, and the far-right section shows the details of the selected step or operation. The far-right section can display the following tabs, depending on the type of step or operation selected12:

Operations: This tab shows the list of available operations that can be added to the pattern, such as Execute Command, Parse File, Set Parameter Value, etc. Operations are the basic building blocks of a pattern that perform specific actions on the target device or the MID Server.

CI Attributes: This tab shows the list of attributes that can be set or updated for the CI type of the pattern, such as name, serial number, manufacturer, etc. CI attributes are used to populate the CI record in the CMDB with the information collected by the pattern.

Temporary Variables: This tab shows the list of temporary variables that can be created or used by the pattern, such as $result, $output, $user_var, etc. Temporary variables are used to store and manipulate data within the pattern, such as the output of a command, the value of a parameter, or the result of a calculation.

CMDB Dashboard: This tab shows the CMDB dashboard that displays the CI record and its related lists, such as relationships, identification rules, sensors, etc. The CMDB dashboard is used to preview and verify the outcome of the pattern on the CI record in the CMDB.

 When Discovery or Service Mapping identifies a CI that matches an existing CI in the CMDB, it checks whether the CIs are duplicates or not. If they are duplicates, Discovery adds them to a de-duplication task, which is a record that groups duplicate CIs and allows you to review and remediate them. You can use the Duplicate CI Remediator wizard to merge, flag, retire, or delete the duplicate CIs. By default, Discovery does not send notifications, create identification rules, or stop the next discovery for duplicate CIs.
