SmartSource Site ID 

The SmartSource Site id (DCSID) is generated when you create a data source or space in Webtrends On Demand, or when you create an SDC data source in Webtrends Marketing Lab. In both cases, a unique DCSID is created.

JavaScript Example:
window.webtrendsAsyncInit = function () {
	var dcs = new Webtrends.dcs();
	dcs.init( {
		dcsid: "dcs9x99xxxx9xxx9xx9xxxx9x_9x9x"
	});
	dcs.track();
}
