# Class CIM_CIMOMStatisticalData
extends CIM_StatisticalData

CIM_CIMOMStatisticalData provides statistical data about the performance of the CIM Object Manager. Each object of this class provides elapsed time and size data for a particular type of CIM operation. All operations of that type, regardless of the CIM operations protocol being used, are accumulated in one object and covers the CIM operations issued by all clients of the Object Manager scoping the instance. Batched CIM operations are accumulated into a separate operation type for "Batched". The counters in this class SHOULD be implemented such that they always increment and naturally wrap around when their numerical limit is exceeded. A client that calculates the difference of two snapshots of a counter at the beginning and end of a measurement interval should get the correct result, even if there was a wrap-around in between obtaining the two snapshots. (Two or more wrap arounds will result in wrong data being calculated.) The gathering of the data can be controlled through the property, CIM_ObjectManager.GatherStatisticalData. The time interval to which the statistical data applies, ends at the current time and therefore includes the most current CIM operations. The interval starts when the statistical data gathering was last turned on for the Object Manager.

Name | Data Type | Value
CimomElapsedTime | datetime |

Description

string

The CimomElapsedTime property contains the elapsed time spent in the CIM Object Manager for this operation type, not counting the elapsed time spent in providers and the underlying instrumentation. The measurement points for this property SHOULD be at the transport layer interface on the network side, and at the provider interface on the instrumentation side of the CIM Object Manager.

Required | boolean | true
InstanceID | string |
Description | string | The InstanceID property opaquely identifies a unique instance of CIMOMStatisticalData and MUST be unique within a namespace. In order to ensure uniqueness, the value of InstanceID MUST be constructed in the following manner: CIM<ID> The <ID> MUST include a CIM Object Manager specified unique identifier.
Key | boolean | true
Override | string | InstanceID
NumberOfOperations | uint64 |
Counter | boolean | true
Description | string | The NumberOfOperations property contains the number of CIM operations of the specified type. This property can be used to calculate average values per CIM operation.
Required | boolean | true
OperationType | uint16 |
Description | string | The OperationType property identifies the type of CIM operation for which data is reported in this instance. Batched CIM operations (consisting of multiple simple CIM operations) are reported against the "Batched" type only.
ModelCorrespondence | string | CIM_CIMOMStatisticalData.OtherOperationType
Required | boolean | true
ValueMap | string | 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26

OtherOperationType | string |
Description | string | The OtherOperationType property identifies the operation if the OperationType property has a value of 1 ("Other"). For all other values of OperationType, the property is NULL.
MaxLen | uint32 | 64
ModelCorrespondence | string | CIM_CIMOMStatisticalData.OperationType
ProviderElapsedTime | datetime |
Description | string | The ProviderElapsedTime property contains the elapsed time spent in all providers involved with this operation type, including the underlying instrumentation. The measurement point for this property SHOULD be from the provider interface of the CIM Object Manager.
Required | boolean | true
RequestSize | uint64 |
Counter | boolean | true
Description | string | The RequestSize property contains the size of the operation requests sent to the CIM Object Manager. Any overhead of protocols above the transport protocol SHOULD be included in the count. For example, for the HTTP protocol, the size would include the size of the HTTP payload and the size of the HTTP headers.
PUnit | string | byte
Units | string | Bytes
ResponseSize | uint64 |
Counter | boolean | true
Description | string | The ResponseSize property contains the size of the operation responses sent back from the CIM Object Manager. Any overhead of protocols above the transport protocol SHOULD be included in the count. For example, for the HTTP protocol, the size would include the size of the HTTP payload and the size of the HTTP headers.
