Represents a relationship between two management pack classes.
When a relationship type is declared in a management pack, it must use one of the following three base relationship types:
- Reference. Parent and child classes are not
dependent on each other. For example, a database could reference
another database that it is replicating. The existence of each of
the databases is not dependent on the other, and the objects are
discovered separately. There is no restriction on the number of
sources that can be connected to a single target or the number of
targets that can be connected to a single source. This constitutes
a many-to-many relationship type.
- Containment. One class can be contained
within another class. For example, a computer is contained within a
computer group, but the computer can exist even if it is not part
of a computer group. This constitutes a many-to-many relationship
- Hosting. The instance of a class can exist
only when it is hosted within another class. For example, a hosting
relationship exists when a Structured Query Language (SQL) database
is hosted within an instance of Microsoft SQL Server. An
instance of the target class can be hosted only by an instance of
the source class, and it cannot be part of any other hosting
relationship. A member of the target class can be hosted only by an
instance of the source class, and it cannot be part of any other
hosting relationship. This constitutes a one-to-many relationship
All relationship types require a source class and a target class. The source and target objects must have been created by the MOMDiscoveryData.CreateClassInstance method of the discovery data object.
An example of this object is shown in the MOMDiscoveryData. CreateRelationshipInstance method.
Adds a new property value to the relationship instance.
Gets or sets the value of the relationship instance source.
Gets or sets the monitoring object to which this relationship instance is targeted.
