The SNMP Query operation on a pattern for a custom device query allows Discovery to retrieve information from the target device using the SNMP protocol. It is best practice to use the published manufacturer's device MIB, which is the official and standard definition of the device's SNMP data. Using the manufacturer's device MIB ensures that the query is accurate, consistent, and compatible with the device.Modifying the default MIB information, enabling SSH as a secondary protocol, or using live devices in production are not recommended practices, as they may introduce errors, security risks, or performance issues123.

Horizontal discovery patterns are a series of operations that tell Discovery which CIs to find on your network, what credentials to use, and what tables to populate in the CMDB. Horizontal discovery patterns use variables to store and pass information between the operations. By default, there are two variables that are automatically available for horizontal discovery patterns: infrastructure_system and computer_system. These variables store the information about the infrastructure and the computer system of the target CI, respectively.They are populated by the Horizontal Pattern probe and sensor, which enable Discovery to use patterns for horizontal discovery123.

In the ServiceNow Discovery module, under the Recommended Actions pane for an Automated Error Messages list within Discovery > Home, the possible options under ACTION ON ALL include 'View instructions' and 'Retry Discovery'. 'View instructions' allows users to see guidance on how to address the errors, while 'Retry Discovery' enables users to reinitiate the discovery process for the affected devices. 'Make Ranges' and 'Ping IP Addresses' are not standard options in this context. Reference = ServiceNow Discovery documentation and user guides, particularly those discussing the management of automated error messages and recommended actions in Discovery.

A horizontal discovery pattern is a series of operations that tell Discovery how to find and identify an application on a host1. To extract the build and version numbers from the config file, the pattern can use either of the following methods:

Parse File operation with Delimited Text parsing strategy: This operation reads the content of a file and splits it into fields based on a delimiter character.The pattern can specify the delimiter as a space and the fields to extract as the second and fourth ones from the first line of the file2.

Parse File operation with Regular Expression parsing strategy: This operation reads the content of a file and matches it against a regular expression.The pattern can specify the regular expression asapp build (\d+\.\d+\.\d+\.\d+) version (\d+\.\d+)and the groups to extract as the first and second ones from the first line of the file2.

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.
