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. References = 1: ITOM: Extending Discovery/Service Mapping Patterns - GlideFast ServiceNow 2: How to Create Discovery Pattern Extensions and Why to Use Them

For discovering Windows Servers, ServiceNow Discovery recommends using credentials that have a domain user account with local administrator access on the target servers. This level of access ensures that Discovery can successfully execute the necessary probes and sensors to collect comprehensive data about the server without being restricted by permission limitations. The other options either provide excessive permissions (like a domain administrator with sudo access) or insufficient privileges (like a standard domain user with read access).

File-based Discovery is a process that helps identify what software is running on your Windows and UNIX servers and devices, even if there is no registration information available. File-based Discovery is triggered in the exploration phase of normal Discovery, after the target device has been classified and identified. File-based Discovery probes execute a scan searching for specific file extensions or file names in paths that you configure. The resulting file information is returned in the probe payload. The sensor attempts to match the discovered files with installed software, using the file name, size, and version returned by the probe.
