SYS.Stats.Disk

Class SYS.Stats.Disk Extends SYS.WSMon.wsResource [ Deprecated, System = 4 ]

DEPRECATED: the system no longer captures the statistics that this class represents. All values will report zero.

This class represents detailed system metrics captured for global disk activity. Each property is a different metric. A class may be instantiated by calling the class method 'Sample', and then the current value of each property can be accessed.

For example: s ref=##class(SYS.Stats.Disk).Sample() w ref.LogDir ; display number of logical reads for directory blocks
Note that in the ^GLOSTAT utility, the numbers displayed as "Logical Block Requests" are the total of Logical Reads and Physical Reads for a category. Individual counts for disk blocks read and written
