System.Discovery.ClassSnapShotDataMapper

System Center

Updated: August 10, 2011

Applies To: Operations Manager 2007 R2

The System.Discovery.ClassSnapshotDataMapper module is a condition detection module type that maps any type of data to class type instance System.Discovery.Data data.

Usage

This module is only used in discovery workflows. Use this module when you want to map any type of data to class type instance System.Discovery.Data. This module only maps a single class type instance. Generally, this module is used as a member module in various existing discovery data source module type definitions. Rarely will you have to use this module directly. See the “External Module References” section later in this topic to see which modules use this module as a member module.

Parameters

System.Discovery.ClassSnapshotDataMapper supports the configuration parameters described in the following table.

 

Parameter Type Overrideable Description

ClassId

String

False

Required parameter. The class that is being discovered.

InstanceSettings

SettingsType

False

Optional parameter. The property settings for the instance or instances of the class that is being discovered.

The ClassID parameter takes a string that must be in the $MPElement format. This element must refer to a defined class in the same management pack or a publicly available class in a referenced management pack. The following XML snippet shows the ClassID configuration element.

<ClassId>$MPElement[Name="Microsoft.Samples.ApplicationX"]$</ClassId>

The InstanceSettings parameter defines the mapping of configuration, data, target, and static values to the discovered instance or instances. The exact mapping depends on the discovery scenario and the hosting relationships that are related to the class that is being discovered. For more information about the InstanceSettings parameter, see SettingsType.
