In ServiceNow Discovery, a horizontal discovery pattern refers to the logical set of steps that the Discovery process executes to find CI information across the network. Each step in a horizontal discovery pattern performs specific operations such as running probes, executing commands, or querying databases to gather information about the configuration items (CIs). It's about expanding the breadth of discovery across devices and applications, rather than going in-depth into a specific CI's details, which would be vertical discovery. Classifiers, credential depots, and port scanning tools are part of the discovery process but do not describe the horizontal discovery pattern itself.

The Duplicate CI Remediator is a feature of ServiceNow Discovery that helps to identify and merge duplicate CIs in the CMDB. It uses predefined rules and criteria to compare CIs across different data sources and determine if they are duplicates. It also provides a user interface to review and approve the suggested merges, or to manually merge CIs as needed. The Duplicate CI Remediator helps to improve the accuracy and quality of the CMDB data and reduce the maintenance efforts.

London Linux Servers is aCMDB Group with Health Group type.A CMDB Group is a collection of configuration items (CIs) that share common characteristics or are related in some way1.A Health Group is a type of CMDB Group that is used to monitor and measure the health of a specific set of CIs based on predefined rules and metrics2.The image shows that London Linux Servers is selected from the CMDB Health Group List, which is a dropdown menu that displays all the Health Groups defined in the system3. The image also shows the Group Health tab, which displays the health scores and indicators for the selected Health Group.

Horizontal pattern types are used to discover the configuration items (CIs) that belong to a specific category or class, such as infrastructure or application. They define the operations that Discovery performs to identify and classify the CIs, and the attributes that Discovery populates for each CI.Horizontal patterns can be applied to any operating system or platform that supports the required protocols and commands12.

The image provided shows a ServiceNow expression used to concatenate two pieces of information. The $name_details[1] suggests that 'name_details' is an array or a list variable, and we're accessing the second element (considering indexing starts at 0). This indicates that 'name_details' is not a tabular variable but rather a list or an array, and there is a scalar value labeled '1' which is being used to index this array. The 'exec_info' and 'executableDir' are likely attributes or properties of the objects within the 'name_details' array and '$process' object, respectively. There is no indication that this is from a WMI query operation step, nor is there any inherent reason why this value could not be used in a pattern step. ServiceNow Discovery patterns can use such expressions to extract and concatenate data during the discovery process.
