TrackingProfile.ActivityTrackPoints Property

  • Reference

Definition

Namespace:
System.Workflow.Runtime.Tracking
Assembly:
System.Workflow.Runtime.dll

Gets the collection of activity track points used by the runtime tracking infrastructure to filter activity status events.

public:
 property System::Workflow::Runtime::Tracking::ActivityTrackPointCollection ^ ActivityTrackPoints { System::Workflow::Runtime::Tracking::ActivityTrackPointCollection ^ get(); };
public System.Workflow.Runtime.Tracking.ActivityTrackPointCollection ActivityTrackPoints { get; }
member this.ActivityTrackPoints : System.Workflow.Runtime.Tracking.ActivityTrackPointCollection
Public ReadOnly Property ActivityTrackPoints As ActivityTrackPointCollection

Property Value

ActivityTrackPointCollection

An ActivityTrackPointCollection that specifies the points in a workflow instance for which the runtime tracking infrastructure should send an ActivityTrackingRecord to the tracking service.

Examples

The following code example demonstrates how you can create a TrackingProfile using the TrackingProfile constructor and use the object's properties to help track the execution of a workflow. The example code uses the ActivityTrackPoints, Version, and WorkflowTrackPoints properties.

This code example is part of the Query using SQLTrackingService SDK sample from the Program.cs file. For more information, see Query Using SQLTrackingService.

private static void CreateAndInsertTrackingProfile()
{
    TrackingProfile profile = new TrackingProfile();
    ActivityTrackPoint activityTrack = new ActivityTrackPoint();
    ActivityTrackingLocation activityLocation = new ActivityTrackingLocation(typeof(Activity));
    activityLocation.MatchDerivedTypes = true;
    IEnumerable<ActivityExecutionStatus> statuses = Enum.GetValues(typeof(ActivityExecutionStatus)) as IEnumerable<ActivityExecutionStatus>;
    foreach (ActivityExecutionStatus status in statuses)
    {
        activityLocation.ExecutionStatusEvents.Add(status);
    }

    activityTrack.MatchingLocations.Add(activityLocation);
    profile.ActivityTrackPoints.Add(activityTrack);
    profile.Version = version;

    WorkflowTrackPoint workflowTrack = new WorkflowTrackPoint();
    WorkflowTrackingLocation workflowLocation = new WorkflowTrackingLocation();
    IEnumerable<TrackingWorkflowEvent> eventStatuses = Enum.GetValues(typeof(TrackingWorkflowEvent)) as IEnumerable<TrackingWorkflowEvent>;
    foreach (TrackingWorkflowEvent status in eventStatuses)
    {
        workflowLocation.Events.Add(status);
    }

    workflowTrack.MatchingLocation = workflowLocation;
    profile.WorkflowTrackPoints.Add(workflowTrack);

    TrackingProfileSerializer serializer = new TrackingProfileSerializer();
    StringWriter writer = new StringWriter(new StringBuilder(), CultureInfo.InvariantCulture);
    serializer.Serialize(writer, profile);
    string trackingprofile = writer.ToString();
    InsertTrackingProfile(trackingprofile);
}

Shared Sub CreateAndInsertTrackingProfile()
    Dim profile As TrackingProfile = New TrackingProfile()

    Dim activityTrack As ActivityTrackPoint = New ActivityTrackPoint()
    Dim activityLocation As ActivityTrackingLocation = New ActivityTrackingLocation(GetType(Activity))
    activityLocation.MatchDerivedTypes = True
    Dim statuses As IEnumerable(Of ActivityExecutionStatus) = CType(System.Enum.GetValues(GetType(ActivityExecutionStatus)), IEnumerable(Of ActivityExecutionStatus))
    For Each status As ActivityExecutionStatus In statuses
        activityLocation.ExecutionStatusEvents.Add(status)
    Next

    activityTrack.MatchingLocations.Add(activityLocation)
    profile.ActivityTrackPoints.Add(activityTrack)
    profile.Version = version

    Dim workflowTrack As WorkflowTrackPoint = New WorkflowTrackPoint()
    Dim workflowLocation As WorkflowTrackingLocation = New WorkflowTrackingLocation()
    Dim eventStatuses As IEnumerable(Of TrackingWorkflowEvent) = CType(System.Enum.GetValues(GetType(TrackingWorkflowEvent)), IEnumerable(Of TrackingWorkflowEvent))
    For Each status As TrackingWorkflowEvent In eventStatuses
        workflowLocation.Events.Add(status)
    Next

    workflowTrack.MatchingLocation = workflowLocation
    profile.WorkflowTrackPoints.Add(workflowTrack)

    Dim serializer As TrackingProfileSerializer = New TrackingProfileSerializer()
    Dim writer As StringWriter = New StringWriter(New StringBuilder(), CultureInfo.InvariantCulture)
    serializer.Serialize(writer, profile)
    Dim trackingProfile As String = writer.ToString()
    InsertTrackingProfile(trackingProfile)
End Sub

Remarks

A workflow instance emits activity status events to the runtime tracking infrastructure whenever the ActivityExecutionStatus of an activity instance changes. The runtime tracking infrastructure uses the ActivityTrackPoints property to filter these activity status events to determine when to send an ActivityTrackingRecord to the tracking service. You can add an ActivityTrackPoint to the ActivityTrackPoints property to specify points of interest in the potential execution path of the workflow instance for which you want the runtime infrastructure to send an ActivityTrackingRecord.

An ActivityTrackPoint does not actually define a physical point in a workflow instance, but instead defines a set of match parameters that can be used by the runtime tracking infrastructure to match an activity status event for which it should send an ActivityTrackingRecord. Therefore, the same ActivityTrackPoint can be matched many times during the lifespan of a workflow instance. An ActivityTrackPoint can also specify data to be extracted from the workflow instance and returned in the ActivityTrackingRecord.
