Represents a relationship between two monitoring 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
upon each other. For example, a database could reference another
database that it is replicating. The existence of each of the
databases is not dependent upon 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 only exist when it
is hosted within another class. For example a hosting relationship
exists when an SQL database is hosted within an instance of 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
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 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.
