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.

An extension section of a discovery pattern is a section that allows you to modify or extend the functionality of an existing pattern without customizing it. An extension section can contain shared libraries, which are reusable code snippets that can be invoked from any pattern or extension section. Shared libraries can be used to define common functions, variables, or constants that are used across multiple patterns or extension sections.Shared libraries can also be used to override the default behavior of some built-in functions, such as identification or classification12.Reference=1: ITOM: Extending Discovery/Service Mapping Patterns - GlideFast ServiceNow2: How to Create Discovery Pattern Extensions and Why to Use Them

The Parse File operation is used to extract information from a file and create variables to contain the extracted information1.The two main options within a Parse File operation areSelect FileandDefine Parsing2. Select File allows you to specify the file path or browse to the file.Define Parsing allows you to select the relevant parsing strategy and define parsing criteria2.

The Automation Error Messages list displays the errors that occurred during the execution of Discovery automation scripts. From this list, you can view the details of each error, such as the script name, the error message, the device, and the time. You can also perform actions on the errors, such as retrying the script, ignoring the error, or creating an incident.To do so, you can use the options on the right navigation pane, which are categorized as follows1:

SELECT ALL: This option allows you to select all the errors in the list.

SELECT ONE: This option allows you to select one error in the list by clicking on the checkbox next to it.

ACTION ON SELECTED: This option allows you to perform an action on the selected errors, such as Retry, Ignore, or Create Incident. You can also choose to perform the action on all the errors in the list by selecting the All option from the drop-down menu.

ACTION ON ALL: This option allows you to perform an action on all the errors in the list, regardless of the selection. You can choose from the same actions as the ACTION ON SELECTED option.

The Put file operation allows the transfer of a file from the MID Server to a target1.This operation can be used to copy files from the MID Server to a target device, such as configuration files, scripts, or binaries2.The Put file operation requires the file path on the MID Server and the file path on the target as inputs2.
