Abstract class CIM_ManagedSystemElement
- extends CIM_ManagedElement
General Information:
CIM_ManagedSystemElement is the base class for
the System Element hierarchy. Any distinguishable component of a System is a
candidate for inclusion in this class. Examples of system components include:
- software components such as application servers, databases, and
applications
- operating system components such as files, processes, and
threads
- device components such as disk drives, controllers, processors,
and printers
- physical components such as chips and
cards.

ElementName
public string ElementName
- General Information:
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.

InstanceID
public string InstanceID
- General Information:
InstanceID is an optional property that may
be used to opaquely and uniquely identify an instance of this class within the
scope of the instantiating Namespace. Various subclasses of this class may
override this property to make it required, or a key. Such subclasses may also
modify the preferred algorithms for ensuring uniqueness that are defined
below.
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 that is creating or defining the InstanceID or that is a
registered ID assigned to the business entity by a recognized global
authority. (This requirement 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 reused to identify different underlying (real-world) elements.
If not null and the above "preferred" algorithm is not used, the defining
entity must assure that the resulting InstanceID is not reused across any
InstanceIDs produced by this or other providers for the NameSpace of this
instance.
If not set to null for DMTF-defined instances, the "preferred"
algorithm must be used with the <OrgID> set to
CIM.

InstallDate
public datetime InstallDate
- General Information:
A datetime value that indicates when the
object was installed. Lack of a value does not indicate that the object is not
installed.

Name
public string Name
- General Information:
The Name property defines the label by
which the object is known. When subclassed, the Name property can be
overridden to be a Key
property.

OperationalStatus
public uint16[] OperationalStatus
- General Information:
Indicates the current statuses of the
element. Various operational statuses are defined. Many of the enumeration's
values are self-explanatory. However, a few are not and are described here in
more detail.
"Stressed" indicates that the element is functioning, but
needs attention. Examples of "Stressed" states are overload, overheated, and
so on.
"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 state and configuration of the element might need to be
updated.
"Dormant" indicates that the element is inactive or quiesced.
"Supporting Entity in Error" indicates that this element might 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 that the element has completed its
operation. This value should be combined with either OK, Error, or Degraded so
that a client can tell if the complete operation Completed with OK (passed),
Completed with Error (failed), or Completed with Degraded (the operation
finished, but it did not complete OK or did not report an error).
"Power
Mode" indicates that 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 because it
required the deprecated qualifier. Due to the widespread use of the existing
Status property in management applications, it is strongly recommended that
providers or instrumentation provide both the Status and OperationalStatus
properties. Further, the first value of OperationalStatus should contain the
primary status for the element. When instrumented, Status (because it is
single-valued) should also provide the primary status of the
element.

StatusDescriptions
public string[] StatusDescriptions
- General Information:
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. Note that entries in this array are
correlated with those at the same array index in
OperationalStatus.

Status
public string Status
- General Information:
A string indicating the current status of
the object. Various operational and non-operational statuses are defined. This
property is deprecated in lieu of OperationalStatus, which includes the same
semantics in its enumeration. This change is made for 3 reasons:
1) Status
is more correctly defined as an array. This definition overcomes the
limitation of describing status using a single value, when it is really a
multi-valued property (for example, an element might be OK AND Stopped.
2)
A MaxLen of 10 is too restrictive and leads to unclear enumerated values.
3) The change to a uint16 data type was discussed when CIM V2.0 was
defined. However, existing V1.0 implementations used the string property and
did not want to modify their code. Therefore, Status was grandfathered into
the Schema. Use of the deprecated qualifier allows the maintenance of the
existing property, but also permits an improved definition using
OperationalStatus.

HealthState
public uint16 HealthState
- General Information:
Indicates the current health of the
element. This attribute expresses the health of this element but not
necessarily that of its subcomponents. The possible values are 0 to 30, where
5 means the element is entirely healthy and 30 means the element is completely
non-functional. The following continuum is defined:
"Non-recoverable
Error" (30) - The element has completely failed, and recovery is not possible.
All functionality provided by this element has been lost.
"Critical
Failure" (25) - The element is non-functional and recovery might not be
possible.
"Major Failure" (20) - The element is failing. It is possible
that some or all of the functionality of this component is degraded or not
working.
"Minor Failure" (15) - All functionality is available but some
might be degraded.
"Degraded/Warning" (10) - The element is in working
order and all functionality is provided. However, the element is not working
to the best of its abilities. For example, the element might not be operating
at optimal performance or it might be reporting recoverable errors.
"OK"
(5) - The element is fully functional and is operating within normal
operational parameters and without error.
"Unknown" (0) - The
implementation cannot report on HealthState at this time.
DMTF has
reserved the unused portion of the continuum for additional HealthStates in
the future.
