    Key Features

    • Command Validation Tool: Introduced in version 3.0.0 (Feb 2023), this tool enables discovery administrators to troubleshoot credential-related discovery issues by auto-fetching commands from pattern code and validating shell, WMI, SNMP, and HTTP GET commands with flexible MID Server selection options.
    • Discovery CLI Enhancements: Starting from version 3.3.0, a suite of CLI commands dedicated to discovery simplifies tasks and improves workflow efficiency. Subsequent fixes improved command execution reliability across platforms and resolved authorization issues.
    • Access Control Improvements: Version 3.10.0 added predefined query access controls for all Pattern Designer Enhancements tables, and version 3.9.0 introduced a new read-only role (pdeviewer) and enforced stricter client-side protections to safeguard read-only fields from modification via scripts or APIs.
    • Command Extraction and OS Detection: Enhancements in versions 3.9.1 and 3.8.0 improved command extraction from nested and eval script blocks and refined OS class detection by accounting for shared library inheritance, increasing accuracy in command classification.
    • Pattern Command Support: Added support for listing pattern commands with temporary variables and framework support for execution (version 3.1.0).
    • Removal of Discovery CLI GUI Feature: In version 3.7.0, the Discovery CLI feature was removed, while core functions remain accessible through the graphical user interface.

    Key Outcomes

    • Improved security and access management within Pattern Designer Enhancements, reducing risk of unauthorized data changes.
    • Enhanced troubleshooting capabilities for discovery command validation, leading to faster resolution of credential and command execution issues.
    • More accurate discovery command detection and OS classification, improving discovery data quality.
    • Streamlined discovery operations with CLI tools and automated command management, boosting administrator productivity.
