Property KBytesWritten KBytesRead IOTimeCounter Type Unit64 Unit64 Unit64 ReadIOTimeCounter Unit64 WriteIOTimeCounter Unit64 TPD_DiskStatisticalData Description The cumulative count of data read in Kbytes (1024bytes = 1KByte). The cumulative count of data transferred in Kbytes (1024bytes = 1KByte). The cumulative elapsed I/O time (number of Clock Tick Intervals) for all I/Os as defined in 'Total I/Os'. This value can be divided by number of IOs to obtain an average response time. ClockTickInterval value can be obtained from TPD_BlockStatisticsCapabilities. It is set to 1 microsecond. The cumulative elapsed time for all Read I/Os for all cumulative Reads. The cumulative elapsed time for all Write I/Os for all cumulative Writes. Property Type Description StatisticTime DateTime Time the statistics is collected StartStatisticsTime DateTime The time, relative to the disk where the statistic was collected, when the first measurement was taken. If the statistic is reset, the StartStatisticTime is the time when the reset was performed. ElementType Unit16 Disk Drive (10) Defines the role that the element played for which this statistics record was collected. TotalIOs Unit64 The cumulative count of I/Os. ReadIOs Unit64 The cumulative count of all reads. WriteIOs Unit64 The cumulative count of all writes. KBytesTransferred Unit64 The cumulative count of data transferred in Kbytes (1024bytes = 1KByte). KBytesWritten Unit64 The cumulative count of data written in Kbytes (1024bytes = 1KByte). KBytesRead Unit64 The cumulative count of data read in Kbytes (1024bytes = 1KByte). IOTimeCounter Unit64 The cumulative elapsed I/O time (number of Clock Tick Intervals) for all I/Os as defined in 'Total I/Os'. This value can be divided by number of IOs to obtain an average response time. ClockTickInterval value can be obtained from TPD_BlockStatisticsCapabilities. It is set to 1 microsecond. ReadIOTimeCounter Unit64 The cumulative elapsed time for all Read I/Os for all cumulative Reads. WriteIOTimeCounter Unit64 The cumulative elapsed time for all Write I/Os for all cumulative Writes. ReadServiceTimeCounter Unit64 The service time since system start time, using ClockTickInterval units, for the Read I/Os. WriteServiceTimeCounter Unit64 The service time since system start time, using ClockTickInterval units, for the Write I/Os. TotalServiceTimeCounter Unit64 The service time since system start time, using ClockTickInterval units, for the total I/Os.
