## Class Methods

### Local Class Methods

#### GetStatisticsCollection (uint32)

#### Method Qualifiers (GetStatisticsCollection)

Name | Data Type | Value
--- | --- | ---

Description

string

Retrieves statistics in a well-defined bulk format. The collection of statistics returned is determined by the list of element types passed in to the method and the manifests for those types contained in the supplied BlockStatisticsManifestCollection. If both the Elements and BlockStatisticsManifestCollection parameters are supplied, then the types of elements returned is an intersection of the element types listed in the Elements parameter and the types for which BlockStatisticsManifest instances exist in the supplied BlockStatisticsManifestCollection. The statistics are returned through a well-defined array of strings, whose format is specified by the StatisticsFormat parameter, that can be parsed to retrieve the desired statistics as well as limited information about the elements that those metrics describe.

ValueMap | string | 0, 1, 2, 3, 4, 5, .., 4096, 4097, 4098, 4099..32767, 32768..65535
Values | string | Job Completed with No Error, Not Supported, Unknown, Timeout, Failed, Invalid Parameter, Method Reserved, Method Parameters Checked - Job Started, Element Not Supported, Statistics Format Not Supported, Method Reserved, Vendor Specific

#### Method Parameters (GetStatisticsCollection)

Name | Type | Qualifiers
--- | --- | ---
Name | Data Type | Value
StatisticsFormat | uint16
Description | string | Specifies the format of the Statistics output parameter. - CSV = Comma Separated Values.
IN | boolean | true
ValueMap | string | 0, 1, 2, .., 0x8000..
Values | string | Unknown, Other, CSV, DMTF Reserved, Vendor Specific
ElementTypes | uint16[]

Description

string

Element types for which statistics should be returned. If not supplied (i.e. parameter is null) this parameter is not considered when filtering the instances of StatisticalData that will populate the Statistics output parameter. If the array is not null, but is empty, then no statistics will be returned by this method. A client SHOULD NOT specify this parameter if it is not meaningful (i.e. the service only provides statistics for a single type of element).

IN | boolean | true
ModelCorrespondence | string | CIM_BlockStorageStatisticalData.ElementType
ValueMap | string | 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, .., 0x8000..
Values | string | 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
Statistics | string[]
Description | string | The statistics for all the elements as determined by the Elements, ManifestCollection parameters, and StatisticsFormat parameters.
ModelCorrespondence | string | CIM_BlockStatisticsService.GetStatisticsCollection(ElementTypes), CIM_BlockStatisticsService.GetStatisticsCollection(ManifestCollection), CIM_BlockStatisticsService.GetStatisticsCollection(StatisticsFormat)
OUT | boolean | true
Job | REF CIM_ConcreteJob
Description | string | Reference to the job (may be null if job completed).
IN | boolean | false
OUT | boolean | true
ManifestCollection | REF CIM_BlockStatisticsManifestCollection

Description

string

The BlockStatisticsManifestCollection that contains the manifests that list the metrics to be returned for each element type. If not supplied (i.e. parameter is null), then all available statistics will be returned unfiltered. Only elements that match the element type properties (if meaningful) of the BlockStatisticsManifest instances contained within the BlockStatisticsManifestCollection will have data returned by this method. If the supplied BlockStatisticsManifestCollection does not contain any BlockStatisticsManifest instances, then no statistics will be returned by this method.

IN | boolean | true

#### CreateManifestCollection (uint32)

#### Method Qualifiers (CreateManifestCollection)

Name | Data Type | Value
--- | --- | ---
Description | string | Creates a new BlockStatisticsManifestCollection instance, whose members can serve as a filter for metrics retrieved through the GetStatisticsCollection method.
ValueMap | string | 0, 1, 2, 3, 4, 5, 6..32767, 32768..65535
Values | string | Ok, Not Supported, Unknown, Timeout, Failed, Invalid Parameter, Method Reserved, Vendor Specific

#### Method Parameters (CreateManifestCollection)

Name | Type | Qualifiers
--- | --- | ---
Name | Data Type | Value

Description | string | Reference to the new BlockStatisticsManifestCollection.
OUT | boolean | true
Statistics | REF CIM_StatisticsCollection
Description | string | The collection of statistics that will be filtered using the new BlockStatisticsManifestCollection.

#### AddOrModifyManifest (uint32)

#### Method Qualifiers (AddOrModifyManifest)

Name | Data Type | Value
--- | --- | ---

Description

string

Method that creates or modifies a BlockStatisticsManifest for this statistics service. A client supplies a BlockStatisticsManifestCollection in which the new BlockStatisticsManifest will be placed or an existing BlockStatisticsManifest will be modified, the element type of the statistics that the BlockStatisticsManifest will filter, and a list of metrics, which serves as a filter for statistical data of that element type.

ValueMap | string | 0, 1, 2, 3, 4, 5, .., 4096, 4097, 4098, 4099..32767, 32768..65535
