OSType property is in 2 classes of ROOT\CIMV2\ms_409 and in 4 namespaces
OtherTypeDescription property
CIMTYPE'string'
Description'A string describing the manufacturer and operating system type - used when the operating system property, OSType, is set to 1 ("Other"). 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.'
OtherTypeDescription property is in 2 classes of ROOT\CIMV2\ms_409 and in 8 namespaces
SizeStoredInPagingFiles property
CIMTYPE'uint64'
Description'The total number of kilobytes that can be stored in the operating system's paging files. Note that this number does not represent the actual physical size of the paging file on disk. 0 indicates that there are no paging files.'
Units'kilobytes'
SizeStoredInPagingFiles property is in 2 classes of ROOT\CIMV2\ms_409 and in 2 namespaces
Status property
CIMTYPE'string'
Description'The Status property is a string indicating the current status of the object. Various operational and non-operational statuses can be defined. Operational statuses are "OK", "Degraded" and "Pred Fail". "Pred Fail" indicates that an element may be functioning properly but predicting a failure in the near future. An example is a SMART-enabled hard drive. Non-operational statuses can also be specified. These are "Error", "Starting", "Stopping" and "Service". The latter, "Service", could apply during mirror-resilvering of a disk, reload of a user permissions list, or other administrative work. Not all such work is on-line, yet the managed element is neither "OK" nor in one of the other states.'
Values['OK', 'Error', 'Degraded', 'Unknown', 'Pred Fail', 'Starting', 'Stopping', 'Service', 'Stressed', 'NonRecover', 'No Contact', 'Lost Comm']
Status property is in 225 classes of ROOT\CIMV2\ms_409 and in 42 namespaces
TotalSwapSpaceSize property
CIMTYPE'uint64'
Description'Total swap space in kilobytes. 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.'
Units'kilobytes'
TotalSwapSpaceSize property is in 2 classes of ROOT\CIMV2\ms_409 and in 2 namespaces
TotalVirtualMemorySize property
CIMTYPE'uint64'
Description'Number of kilobytes of virtual memory. For example, this may be calculated by adding the amount of total RAM to the amount of paging space (i.e., adding the amount of memory in/aggregated by the computer system to the property, SizeStoredInPagingFiles.'
Units'kilobytes'
TotalVirtualMemorySize property is in 2 classes of ROOT\CIMV2\ms_409 and in 2 namespaces
TotalVisibleMemorySize property
CIMTYPE'uint64'
Description'The total amount of physical memory (in Kbytes) available to the OperatingSystem. This value does not necessarily indicate the true amount of physical memory, but what is reported to the OperatingSystem as available to it.'
Units'kilobytes'
TotalVisibleMemorySize property is in 2 classes of ROOT\CIMV2\ms_409 and in 2 namespaces
Version property
CIMTYPE'string'
Description'The Version property indicates the version number of the operating system.
Example: 4.0'
Version property is in 96 classes of ROOT\CIMV2\ms_409 and in 142 namespaces
