Attributes and Elements

The following sections describe attributes, child elements, and parent elements.

Attributes

None.

Child Elements

Element Description
<participants> A collection of configuration elements defining participants that subscribe to tracking records. The tracking participants contain the logic to process the payload from the tracking records (for example, they could choose to write to a file).
<trackingProfile> A tracking profile to filter tracking records emitted from a workflow instance.

Parent Elements

Element Description
system.ServiceModel The root element of all workflow configuration elements.

Remarks

Tracking provides you with the ability to examine the execution of a workflow. The workflow tracking infrastructure instruments a workflow to emit records reflecting key events during the execution. For example, when a workflow instance starts or completes tracking records are emitted. Tracking can also extract business relevant data associated with the workflow variables. For example, if the workflow represents an order processing system the order id can be extracted along with the tracking record. In general, enabling WF tracking facilitates diagnostics or business analytics over a workflow execution.
