If the metered element is a system or a component of a system associated to a RegisteredProfile, then that profile may provide a more specialized definition and additional usage information for this property. Generally, the ElementTypes defined here have the following meaning in the context of this class: 2, "Computer System": Cumulative statistics for the storage system. In the case of a complex system with multiple component Computer Systems, these are the statistics for the top-level aggregate Computer System. 3, "Front-end Computer System": Statistics for a component computer system that communicate with systems that initiate IO requests. 4, "Peer Computer System": Statistics for a component computer system that communicates with peer storage systems e.g. to provide remote mirroring of a volume. 5, "Back-end Computer System": Statistics for a component computer system that communicates with back-end storage. 6, "Front-end Port": Statistics for a port that communicates with systems that initiate IO requests. 7, "Back-end Port": Statistics for a port that initiates IO requests to storage devices. 8, "Volume": Statistics for an exposable storage extent, such as a StorageVolume or LogicalDisk. 9, "Extent": Statistics for an intermediate storage extent, i.e. an extent that is neither a volume or a disk. 10, "Disk Drive: Statistics for a StorageExtent that is associated to a DiskDrive through the MediaPresent association. 11, "Arbitrary LUs": Statistics that derive from access to Logical Units that are NOT StorageVolumes (e.g., controller commands). 12, "Remote Replica Group": Statistics for control IOs between an array and a remote mirror across a Network. Note that statistics for the actual movement of data to the remote mirror are attributed to the targeted StorageVolume (or LogicalDisk). Note that a particular element could be associated to multiple BlockStorageStatisticalData instances if it had multiple roles. For example, a storage array could contain redundant component computer systems that communicate both with hosts on the front end and disks on the back end. Such a device could have one BlockStorageStatisticalData instance where ElementType=3 and another instance where ElementType=5.</TD> </TR> <TR> <TD VALIGN="TOP">Required</TD><TD VALIGN="TOP">boolean</TD><TD VALIGN="TOP">true</TD> </TR> <TR> <TD VALIGN="TOP">ValueMap</TD><TD VALIGN="TOP">string</TD><TD VALIGN="TOP">2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, .., 0x8000..</TD> </TR> <TR> <TD VALIGN="TOP">Values</TD><TD VALIGN="TOP">string</TD><TD VALIGN="TOP">Computer System, Front-end Computer System, Peer Computer System, Back-end Computer System, Front-end Port, Back-end Port, Volume, Extent, Disk Drive, Arbitrary LUs, Remote Replica Group, DMTF Reserved, Vendor Specific</TD> </TR> <TR> <TH ROWSPAN="3" VALIGN="TOP">IdleTimeCounter</TH><TD ROWSPAN="3" VALIGN="TOP">uint64</TD><TD ROWSPAN="3" VALIGN="TOP"></TD> </TR> <TR> <TD VALIGN="TOP">Counter</TD><TD VALIGN="TOP">boolean</TD><TD VALIGN="TOP">true</TD> </TR> <TR> <TD VALIGN="TOP">Description</TD><TD VALIGN="TOP">string</TD><TD VALIGN="TOP">The cumulative elapsed idle time using ClockTickInterval units (Cumulative Number of Time Units for all idle time in the array).</TD> </TR> <TR> <TH ROWSPAN="3" VALIGN="TOP">IOTimeCounter</TH><TD ROWSPAN="3" VALIGN="TOP">uint64</TD><TD ROWSPAN="3" VALIGN="TOP"></TD> </TR> <TR> <TD VALIGN="TOP">Counter</TD><TD VALIGN="TOP">boolean</TD><TD VALIGN="TOP">true</TD> </TR> <TR> <TD VALIGN="TOP">Description</TD><TD VALIGN="TOP">string</TD><TD VALIGN="TOP">The cumulative elapsed I/O time (number of Clock Tick Intervals) for all I/Os as defined in 'Total I/Os'.
