Description
|
string
|
|
The Description property provides a textual description of the object. |
ElementName
|
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.The Name property of ManagedSystemElement is also defined as a user-friendly name. But, it is often subclassed to be a Key. The same property cannot 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. |

EnabledState is an integer enumeration that indicates the enabled and disabled states of an element. It can also indicate the transitions between these requested states. For example, shutting down (value=4) and starting (value=10) are transient states between enabled and disabled. The following text briefly summarizes the various enabled and disabled states:Enabled (2) indicates that the element is or could be running commands, will process any queued commands, and queues new requests.Disabled (3) indicates that the element will not run commands and will drop any new requests.Shutting Down (4) indicates that the element is in the process of going to a Disabled state.Not Applicable (5) indicates the element does not support being enabled or disabled.Enabled but Offline (6) indicates that the element might be completing commands, and will drop any new requests.Test (7) indicates that the element is in a test state.Deferred (8) indicates that the element might be completing commands, but will queue any new requests.Quiesce (9) indicates that the element is enabled but in a restricted mode. The behavior of the element is similar to the Enabled state, but it processes only a restricted set of commands. All other requests are queued.Starting (10) indicates that the element is in the process of going to an Enabled state. New requests are queued. |
HeaderFormat
|
string
|
|
If the SizeOfHeader property is non-zero, this property describes the structure and format of the Log header. It is a free-form string. If the SizeOfHeader property is 0, then the information in this property is undefined. |
InstallDate
|
datetime
|
|
A datetime value indicating when the object was installed. A lack of a value does not indicate that the object is not installed. |
IsFrozen
|
boolean
|
|
Boolean indicating that the Log is currently frozen and modifications are not allowed. |
LastChange
|
uint16
|
Unknown | 0 |
Add | 1 |
Delete | 2 |
Modify | 3 |
Log Cleared | 4 |
|
An enumeration describing the last change to the MessageLog. |
MaxLogSize
|
uint64
|
|
The maximum size, in bytes, to which the Log can grow. If there is no maximum, then MaxLogSize should be set to 0. |
MaxNumberOfRecords
|
uint64
|
|
Maximum number of records that can be capturedin the Log. If undefined, a value of zero should be specified. |
MaxRecordSize
|
uint64
|
|
Maximum size, in bytes, to which an individual Log entry (record) can grow - if the Capabilities array includes a value of 7 ("Variable Length Records Supported"). If the Capabilities array does not include a 7, then the Log only supports fixed length entries. The size of these entries is described by this property. |

Indicates the current status(es) of the element. Various health and operational statuses are defined. Many of the enumeration's values are self- explanatory. However, a few are not and are described in more detail."Stressed"indicates that the element is functioning, but needs attention. Examples of"Stressed"states are overload, overheated, etc."Predictive Failure"indicates that an element is functioning nominally but predicting a failure in the near future."In Service"describes an element being configured, maintained, cleaned, or otherwise administered."No Contact"indicates that the monitoring system has knowledge of this element, but has never been able to establish communications with it."Lost Communication"indicates that the ManagedSystem Element is known to exist and has been contacted successfully in the past, but is currently unreachable."Stopped"and"Aborted"are similar, although the former implies a clean and orderly stop, while the latter implies an abrupt stop where the element's state and configuration may need to be updated."Dormant"indicates that the element is inactive or quiesced."Supporting Entity in Error"describes that this element may be"OK"but that another element, on which it is dependent, is in error. An example is a network service or endpoint that cannot function due to lower layer networking problems."Completed"indicates the element has completed its operation. This value should be combined with either OK, Error, or Degraded so that a client can till if the complete operation passed (Completed with OK), and failure (Completed with Error). Completed with Degraded implies the operation finished, but did not complete OK or report an error."Power Mode"indicates the element has additional power model information contained in the Associated PowerManagementService association.OperationalStatus replaces the Status property on ManagedSystemElement to provide a consistent approach to enumerations, to address implementation needs for an array property, and to provide a migration path from today's environment to the future. This change was not made earlier since it required the DEPRECATED qualifier. Due to the widespread use of the existing Status property in management applications, providers/instrumentation must provide both the Status and OperationalStatus properties. Further, the first value of OperationalStatus will contain the primary status for the element. When instrumented, Status (since it is single-valued) will also provide the primary status of the element. |
OtherEnabledState
|
string
|
|
A string that describes the enabled or disabled state of the element when the EnabledState property is set to 1 ("Other"). This property must be set to null when EnabledState is any value other than 1. |
OtherPolicyDescription
|
string
|
|
When the OverwritePolicy specifies a value of 1 ("Other"), the Log's behavior can be explained using this property. If OverwritePolicy is not 1, then this property's contents are undefined. |
OverwritePolicy

Unknown | 0 |
Other | 1 |
Wraps When Full | 2 |
Clear When Near Full | 3 |
Overwrite Outdated When Needed | 4 |
Remove Outdated Records | 5 |
Overwrite Specific Records | 6 |
Never Overwrite | 7 |
|
An enumeration describing the behavior of the Log, when it becomes full or near full. For example, the Log may wrap (value=2) or may simply stop recording entries (value =7).Some of the property's possible values need further explanation:3="Clear When Near Full"indicates that all of the Log's entries will be deleted when a specified record capacity is reached. The capacity is specified in percentage, using the property, PercentageNearFull.'Near Full'may be less than 100% if the Log takes time to clear, and a position should always be available for new records.4="Overwrite Outdated When Needed"describes that Log entries (timestamped later than the date/time specified in the property, TimeWhenOutdated) can be overwritten.5="Remove Outdated Records"specifies that records (timestamped later than the date/time specified in the property, TimeWhenOutdated) are logically and/or physically removed from the Log.6="Overwrite Specific Records"indicates that specially flagged records may be overwritten. This property only makes sense when the Capabilities array includes a value of 10,"Can Flag Records for Overwrite". |
PercentageNearFull
|
uint8
|
|
If the OverwritePolicy is based on clearing records when the Log is near full (value=3), this property defines the record capacity (in percentage) that is considered to be'near full'. |
RecordHeaderFormat
|
string
|
|
If the SizeOfRecordHeader property is non-zero, this property describes the structure and format of the record headers. It is a free-form string. If the SizeOfRecordHeader property is 0, then the information in this property is undefined. |
RecordLastChanged
|
uint64
|
|
When a change is made to the Log, the record number that was modified is captured. |

RequestedState is an integer enumeration that indicates the last requested or desired state for the element. The actual state of the element is represented by EnabledState. This property is provided to compare the last requested and current enabled or disabled states. When EnabledState is set to 5 ("Not Applicable"), then this property has no meaning. By default, the RequestedState of the element is 5 ("No Change"). Refer to the EnabledState property description for explanations of the values in the RequestedState enumeration.It should be noted that there are two new values in RequestedState that build on the statuses of EnabledState. These are"Reboot"(10) and"Reset"(11). Reboot refers to doing a"Shut Down"and then moving to an"Enabled"state. Reset indicates that the element is first"Disabled"and then"Enabled". The distinction between requesting"Shut Down"and"Disabled"should also be noted. Shut Down requests an orderly transition to the Disabled state, and might involve removing power, to completely erase any existing state. The Disabled state requests an immediate disabling of the element, such that it will not run or accept any commands or processing requests.This property is set as the result of a method invocation (such as Start or StopService on CIM_Service), or can be overridden and defined as WRITEable in a subclass. The method approach is considered superior to a WRITEable property, because it allows an explicit invocation of the operation and the return of a result code.A particular instance of EnabledLogicalElement might not support RequestedStateChange. If this occurs, the value 12 ("Not Applicable") is used. |
SizeOfHeader
|
uint64
|
|
The size of the Log header, in bytes, if one is present. If there is no Log header, then this property should be set to 0. Headers may include general information about the Log such as the current number of records, time of last update, or a pointer to the location of the first Log entry. Note that this property is not the size of the header for an individual Log entry. The latter is described by the property, SizeOfRecordHeader. |
SizeOfRecordHeader
|
uint64
|
|
The size of the header for the Log's individual entries, in bytes, if record headers are defined. If there are no record headers, then this property should be set to 0. Record headers may include information such as the type of the Log entry, the date/time that the entry was last updated, or a pointer to the start of optional data. This property defines the header size for individual records in the Log, while the SizeOfHeader property describes the Log's overall header, typically located at the start ofthe MessageLog. |
StatusDescriptions
|
string
|
|
Strings describing the various OperationalStatus array values. For example, if"Stopping"is the value assigned to OperationalStatus, then this property may contain an explanation as to why an object is being stopped. Entries in this array are correlated with those at the same array index in OperationalStatus. |
TimeOfLastChange
|
datetime
|
|
When a change is made to the Log, the date/time of that modification is captured. This property could be used to event against any update to the MessageLog. |
TimeWhenOutdated
|
datetime
|
|
If the OverwritePolicy is based on'outdated'records (values 4 or 5), this property defines when a Log entry is considered to be outdated - either by time interval or at a specific date and time. |
