    Key Features

    • Command Validation Tool (CVT): Introduced in version 3.0.0 (Feb 2023), CVT helps discovery admins troubleshoot credential-related discovery issues by auto-fetching commands from pattern code and supporting various command types such as Shell, WMI, SNMP queries, and HTTP GET.
    • Discovery CLI: Added in version 3.3.0 (Nov 2023), this suite of CLI commands streamlines discovery processes, improving workflow efficiency. Although the Discovery CLI feature was later removed in version 3.7.0 (May 2025), core functions remain accessible via the GUI.
    • Access Controls and Security: Version 3.10.0 (June 2026) introduced predefined query access controls for all Pattern Designer Enhancements tables. Earlier, version 3.9.0 (Dec 2025) added a new pdeviewer role for read-only access and strengthened client-side protections to prevent unauthorized modifications.
    • Command Detection and Validation Improvements: Enhancements such as extracting commands from eval script blocks, handling nested libraries, and improved OS class detection for commands increase command coverage and accuracy (versions 3.8.0 and 3.9.1).
    • Multi-language Support and User Feedback: Bug fixes and clearer system messages have been applied to improve user experience and internationalization (versions 3.0.1 and 3.4.0).
    • Pattern Command Enhancements: Support for listing pattern commands with temporary variables and framework execution was added in version 3.1.0 (Aug 2023), aiding pattern design and testing.

    Practical Benefits for ServiceNow Customers

    • Enhanced troubleshooting capabilities for discovery patterns reduce time spent diagnosing credential and command execution issues.
    • Improved security controls safeguard pattern data and configurations from unauthorized client-side changes.
    • The phased evolution of CLI and GUI tools offers flexible options to suit different operational preferences.
    • Automated and codeless pattern framework updates simplify discovery of complex on-premises and cloud infrastructure.
    • Clearer system messages and multi-language support help global teams operate discovery tools with greater confidence.
