Column Name Mode Description Data Type
KernMemInuseKB track Amount of Kernel memory in use by PDE in kilobytes.
The ResSpmaView has an alias field called TotalKernMemInuseKB, derived from: KernMemInuseKB + SegMDLInuseKB
FLOAT
SegMDLInuseKB track Total memory in use by segment MDLs. An MDL is an internal PDE data structure needed by the operation of the segment subsystem.

The pages associated with MDL segments are pinned in memory for bynet DMA.

The ResSpmaView has an alias field called TotalKernMemInuseKB, derived from: KernMemInuseKB + SegMDLInuseKB
FLOAT
FsgCacheKB track Allocated memory for FSG cache. This includes the memory allocated for TIM (VHCacheKB). FLOAT
