Inventory NDI files from the high-frequency scan to support IBM sub-capacity calculations are only generated and uploaded if the agent detects a change in a "hardware" property.

The following agent preference provides some control to exclude selected classes & properties from triggering an NDI file to be generated: HardwareChangesClassPropertyBlacklist

There are a range of known issues related to this, where common but generally irrelevant hardware changes trigger these NDI files to be generated. See:

• Unnecessary high-frequency PVU inventory NDI file uploads may be triggered when Win32_OperatingSystem.LastBootUpTime or InstallDate changes (IOJ-2247786)
• Unnecessary high-frequency PVU inventory NDI file uploads may be triggered from devices running Windows by variations in processor clock speed details (IOJ-1852613)
• Unnecessary high-frequency PVU inventory NDI file uploads may be triggered from devices running Unix-like operating systems by variations in processor clock speed details (IOJ-2258785)
• Unnecessary high-frequency PVU inventory NDI file uploads may be triggered by agent scheduled event changes (IOJ-2236677)
• Unnecessary high-frequency PVU inventory NDI file uploads may be triggered when network adapter details change (IOJ-2244446)
