The most common cause. OMI may be running against a Linux/UNIX machine where Win32_OperatingSystem does not exist. OMI can host its own CIM providers on Linux (e.g., OMI_OperatingSystem ), but the classic Win32_ namespace is Windows-only.
The error typically occurs during FortiSIEM integration with Windows hosts when the Open Management Infrastructure (OMI) cannot retrieve basic system information due to network blocks, permission issues, or service misconfigurations .
