Attributes and Elements

The following sections describe attributes, child elements, and the parent element of the DataSourceModuleType element.

Attributes

Attribute	Description
ID	Required attribute. Represents the identity of the element. To learn how to identify your element in a management pack, see Element Identity and Namespace Conventions.
Comment	Optional attribute. Represents commentary by the management pack author.
Accessibility	Required attribute. Defines the visibility of the module type definition.
RunAs	Optional attribute. Refers to a SecureReference type ID. All instances of this module type definition will run under the credentials set for the SecureReference ID. When not specified, the module will run under the default action account.
Batching	Optional attribute. Indicates whether or not the module type can accept a batch of input data at one time. Not relevant for composite module types. Default value is false.

Accessibility Attribute Values

Value	Description
Public	Indicates that the module type definition is visible to external management packs.
Internal	Indicates that the module type definition is not visible to external management packs.

Child Elements

Element	Description
Configuration (DataSourceModuleType)	Required element. Represents the parameters for a monitor or module type definition in XSD schema.
OverrideableParameters (DataSourceModuleType)	Optional element. Contains any overrideable configuration parameters in a monitor or module type definition.
ModuleImplementation (DataSourceModuleType)	Required element. Defines the implementation type for native or managed module type definitions and defines the composite elements for composite module type definitions.
OutputType (DataSourceModuleType)	Required element. Defines the output data type of a module type definition.

Parent Elements

Element	Description
ModuleTypes	Contains module type definitions in a management pack.

Remarks

Data source module types have no input and a single output. Because they take no input, they are usually the first module in any workflow.

Example

The following sample shows two DataSourceModuleType elements. Both are defined in the Microsoft.Windows.Library management pack. The Microsoft.Windows.BaseEventProvider is implemented in native code and is used inside the composite data source module type element Microsoft.Windows.EventCollector. To offer filtering through a condition detection module, the Microsoft.Windows.EventCollector module wraps the functionality of Microsoft.Windows.BaseEventProvider.
