Class Declaration Attributes Name Value SUPERCLASS CIM_StatisticalData NAME CIM_BlockStorageStatisticalData
Class CIM_BlockStorageStatisticalData Qualifiers Name Type Value From Class Experimental boolean true CIM_BlockStorageStatisticalData Version string 2.10.0 CIM_BlockStorageStatisticalData Description string A subclass of StatisticalData which identifies individual statistics for an element of a block storage system. This class defines the metrics that MAY be kept for managed elements of the system. CIM_BlockStorageStatisticalData Description string CIM_StatisticalData is a root class for any arbitrary collection of statistical data and/or metrics applicable to one or more ManagedElements. These statistics MUST represent the most recent observations and MUST NOT be provided if irrelevant or stale. Note that this class uses a simplified naming/identity algorithm as compared to CIM_StatisticalInformation. CIM_StatisticalData Description string ManagedElement is an abstract class that provides a common superclass (or top of the inheritance tree) for the non-association classes in the CIM Schema.

Property Qualifiers
Property ElementType Qualifiers Name Type Value From Class Required boolean true CIM_BlockStorageStatisticalData Description string Defines the role that the element played for which this statistics record was collected. 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.

CIM_BlockStorageStatisticalData Counter boolean true CIM_BlockStorageStatisticalData
Property InstanceID Qualifiers Name Type Value From Class Key boolean true CIM_StatisticalData Description string Within the scope of the instantiating Namespace, InstanceID opaquely and uniquely identifies an instance of this class. In order to ensure uniqueness within the NameSpace, the value of InstanceID SHOULD be constructed using the following ’ preferred ’ algorithm: < OrgID > : < LocalID > Where < OrgID > and < LocalID > are separated by a colon ’ : ’ , and where < OrgID > MUST include a copyrighted, trademarked or otherwise unique name that is owned by the business entity creating/defining the InstanceID, or is a registered ID that is assigned to the business entity by a recognized global authority (This is similar to the < Schema Name > _ < Class Name > structure of Schema class names.) In addition, to ensure uniqueness < OrgID > MUST NOT contain a colon ( ’ : ’ ). When using this algorithm, the first colon to appear in InstanceID MUST appear between < OrgID > and < LocalID > . < LocalID > is chosen by the business entity and SHOULD not be re-used to identify different underlying (real-world) elements. If the above ’ preferred ’ algorithm is not used, the defining entity MUST assure that the resultant InstanceID is not re-used across any InstanceIDs produced by this or other providers for this instance ’ s NameSpace. For DMTF defined instances, the ’ preferred ’ algorithm MUST be used with the < OrgID > set to ’ CIM ’ . CIM_StatisticalData
Property ElementName Qualifiers Name Type Value From Class Required boolean true CIM_StatisticalData Override string ElementName CIM_StatisticalData Description string The user friendly name for this instance of StatisticalData. In addition, the user friendly name can be used as a index property for a search of query. (Note: Name does not have to be unique within a namespace.) CIM_StatisticalData
Property StartStatisticTime Qualifiers Name Type Value From Class Description string The time, relative to managed element 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. CIM_StatisticalData
Property StatisticTime Qualifiers Name Type Value From Class Description string The time the most recent measurement was taken, relative to the managed element where the statistic was collected. CIM_StatisticalData
Property SampleInterval Qualifiers Name Type Value From Class Description string Some statistics are sampled at consistent time intervals. This property provides the sample interval so that client applications can determine the minimum time that new statistics should be pulled. If the statistics are not sampled at consistent time intervals, this property must be set to a zero time interval. CIM_StatisticalData
Property Caption Qualifiers Name Type Value From Class Description string The Caption property is a short textual description (one- line string) of the object. CIM_ManagedElement MaxLen uint32 64 CIM_ManagedElement
Property Description Qualifiers Name Type Value From Class Description string The Description property provides a textual description of the object. CIM_ManagedElement
Property ElementName Qualifiers Name Type Value From Class Description string A user-friendly name for the object. This property allows each instance to define a user-friendly name in addition to its key properties, identity data, and description information. Note that the Name property of ManagedSystemElement is also defined as a user-friendly name. But, it is often subclassed to be a Key. It is not reasonable that the same property can convey both identity and a user-friendly name, without inconsistencies. Where Name exists and is not a Key (such as for instances of LogicalDevice), the same information can be present in both the Name and ElementName properties. CIM_ManagedElement
Name Type Value Qualifiers Parameters ClassOrigin ResetSelectedStats uint32 Description SelectedStatistics CIM_StatisticalData Method Qualifiers
Method ResetSelectedStats Qualifiers Name Type Value From Class Description string Method to reset one or more of the instance ’ s statistics. The method takes one parameter as input - an array of strings indicating which statistics to reset. If all the statistics in the instance should be reset, the first element of the array MUST be set to " All " or " ALL " . If one or more individual statistics should be reset, the corresponding property names are entered into the elements of the array. The method returns 0 if successful, 1 if not supported, and any other value if an error occurred. A method is specified so that the StatisticalInformation ’ s provider/ instrumentation, which calculates the statistics, can reset its internal processing, counters, etc. In a subclass, the set of possible return codes could be specified, using a ValueMap qualifier on the method. The strings to which the ValueMap contents are ’ translated ’ may also be specified in the subclass as a Values array qualifier. CIM_StatisticalData Parameters
