Distributedboolean
DescriptionstringBoolean indicating whether the OperatingSystem is distributed across several ComputerSystem nodes. If so, these nodes should be grouped as a Cluster.None TRANSLATABLE= true

UnitsstringKiloBytesNone TRANSLATABLE= true
FreeSpaceInPagingFilesuint64
DescriptionstringThe total number of KBytes that can be mapped into the OperatingSystem's paging files without causing any other pages to be swapped out. 0 indicates that there are no paging files.None TRANSLATABLE= true

UnitsstringKiloBytesNone TRANSLATABLE= true
FreeVirtualMemoryuint64
DescriptionstringNumber of Kbytes of virtual memory currently unused and available. For example, this may be calculated by adding the amount of free RAM to the amount of free paging space (ie, adding the properties, FreePhysicalMemory and FreeSpaceInPagingFiles).None TRANSLATABLE= true

MaxNumberOfProcessesuint32
DescriptionstringMaximum number of process contexts the OperatingSystem can support. If there is no fixed maximum, the value should be 0.On systems that have a fixed maximum, this object can help diagnose failures that occur when the maximum is reached.None TRANSLATABLE= true

MaxProcessesPerUseruint32
DescriptionstringA value that indicates the maximum processes that a user can have associate with it.None TRANSLATABLE= true
MaxProcessMemorySizeuint64
DescriptionstringMaximum number of Kbytes of memory that can be allocated to a Process. For Operating Systems with no virtual memory, this value is typically equal to the total amount of physical Memory minus memory used by the BIOS and OS. For some Operating Systems, this value may be infinity - in which case, 0 should be entered. In other cases, this value could be a constant - for example, 2G or 4G.None TRANSLATABLE= true

OtherTypeDescriptionstring
DescriptionstringA string describing the manufacturer and OperatingSystem type - used when the OperatingSystem property, OSType, is set to 1 or 59 ("Other" or "Dedicated"). The format of the string inserted in OtherTypeDescription should be similar in format to the Values strings defined for OSType. OtherTypeDescription should be set to NULL when OSType is any value other than 1 or 59.None TRANSLATABLE= true

TotalSwapSpaceSizeuint64
DescriptionstringTotal swap space in Kbytes. This value may be NULL (unspecified) if swap space is not distinguished from page files. However, some Operating Systems distinguish these concepts. For example, in UNIX, whole processes can be 'swapped out' when the free page list falls and remains below a specified amount.None TRANSLATABLE= true
