Often customers want to monitor WCM syndication from a point-to-point viewpoint. The WCM API provides many ways to do this but in this scenario the requirement is to validate that content created on the authoring server can be displayed on rendering server's web site. The design for this implementation is to periodically update a content item on the authoring server and verify that the update appears on the rendering server.
You can then build alarm system to check the content and, if it is too out of date, alert administrators. You would need to define the alarm criteria but for instance if your syndication is on an 30 minute schedule you could raise an alarm if the health heck item is more than 90 minutes old.
