Property Type ReadIOTimeCounter Unit64 WriteIOTimeCounter Unit64 Description 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. TPD_NodeStatisticalData Statistical data for a node controller, including statistics of: • all the ports on the node • cached memory pages • all CPU's on the node Property StatisticTime StartStatisticsTime ElementType TotalIOs ReadIOs WriteIOs KBytesTransferred KBytesWritten KBytesRead IOTimeCounter ReadIOTimeCounter WriteIOTimeCounter ReadHitIOs WriteHitIOs ReadMissIOs WriteMissIOs LockedReadBlocks LockedWriteBlocks FreeCachePages CleanCachePages Write1CachePages 98 CIM API SMI-S Support Type Description DateTime Time the statistics is collected DateTime The time, relative to the node controller 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. Unit16 Peer Computer System (4). Defines the role that the element played for which this statistics record was collected. Unit64 The cumulative count of I/Os. Unit64 The cumulative count of all reads. Unit64 The cumulative count of all writes. Unit64 The cumulative count of data transferred in Kbytes (1024bytes = 1KByte). Unit64 The cumulative count of data written in Kbytes (1024bytes = 1KByte). Unit64 The cumulative count of data read in Kbytes (1024bytes = 1KByte). 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. Unit64 The cumulative elapsed time for all Read I/Os for all cumulative Reads. Unit64 The cumulative elapsed time for all Write I/Os for all cumulative Writes. Unit64 The cumulative count of all read cache hits (Reads from Cache). Unit64 The cumulative count of Write Cache Hits (Writes that went directly to Cache). Unit64 The cumulative count of all Read Cache misses. Unit64 The cumulative count of all Write Cache misses. Unit64 Number of pages being modified by host read I/O that are being written to disk by the flusher. Unit64 Number of pages being modified by host write I/O that are being written to disk by the flusher. Unit32 Number of cache pages without valid data on them. Unit32 Number of clean cache pages (valid data on page). A page is clean when data in cache matches data on disk. Unit32 Number of dirty pages that have been modified exactly 1 time. A page is dirty when it has been modified in cache but not written to disk.
