In the generated C++ file (usually OperatingSystem_Provider.cpp ), you must implement the logic to fetch data. Since this is Windows, you would typically use the Windows API here.
Resolving this issue requires a systematic approach to the management stack. Administrators should first verify local WMI health on the Windows target using PowerShell to ensure the Win32_OperatingSystem class is responsive. Once local health is confirmed, the focus shifts to WinRM configuration, ensuring that the listener is active and that the calling user is part of the Remote Management Users group. Finally, checking for OMI-specific patches on the Linux management node can resolve known bugs in how results are parsed. By addressing these layers—permissions, repository integrity, and protocol configuration—organizations can restore the visibility needed for effective cross-platform orchestration.
In Python:
On the Windows host, locate OMI configuration (often %PROGRAMFILES%\Microsoft OMI\conf\omiserver.conf ). Set: win32-operatingsystem result not found via omi
The error message means that a Linux-based monitoring or security system cannot fetch Windows operating system details over the network using the Open Management Infrastructure (OMI) framework.
If that fails, OMI cannot reach the CIM server.
The error "Win32_OperatingSystem result not found via OMI" is a well-known and well-documented issue in cross-platform Windows management, particularly within the FortiSIEM community. By following the structured, step-by-step troubleshooting guide in this article, you can systematically move from the most common causes to more complex scenarios. In the generated C++ file (usually OperatingSystem_Provider
On Linux, Win32_OperatingSystem isn't built into the core OMI server; it is usually provided by the provider. Check if the SCX package is installed: Ubuntu/Debian: dpkg -l | grep scx RHEL/CentOS: rpm -qa | grep scx
Instead of universally calling Win32_OperatingSystem , query the equivalent Linux CIM class when targeting a Linux node via OMI. Win32_OperatingSystem
If this command fails, the OMI service may be corrupted or missing provider libraries. Restart the service using sudo systemctl restart omid . Administrators should first verify local WMI health on
Locate the omiserver.conf file (usually in /etc/omi/ or the installation directory). Ensure that the module allowing WMI interaction is enabled.
Reinstall/re-register provider
Your WMI repository is corrupted. Proceed immediately to Step 5.
from omi import Client, Query
