Applying the Wait Volumes overlay on a particular action displays the number of waiting instances of the action for the selected Campaign. The overlay displays this count for each wait-enabled shape in the action.

To view this overlay, perform the following steps:

1. Select the Wait Volumes item from the Overlay toolbar menu in the action canvas.
   
   
2. Specify the Campaign for which you wish to view waiting action counts. You can specify either the name or the work id of the Campaign.
   
   
3. Click Submit.

Upon application of the overlay, the count of action waiting is shown on every wait-enabled shape. In addition, the name and work id of the selected Campaign is displayed in the canvas toolbar next to the Overlay menu. The count shown on each shape represents the number of instances of the action that are waiting at the shape and have been initiated as part of the selected Campaign - either via a scheduled run or via a triggered Event.

Hovering over the count on a shape displays an expanded view of the overlay with links to perform the Update Expiration Time for Waiting Actions and Stop Waiting Actions actions.

To view the wait volumes for a different Campaign, re-apply the overlay (by following steps 1-3 above) and select the desired Campaign.

To remove the applied overlay, select the None item from the Overlay menu.
