The Wallboard Builder utilizes real-time metrics to populate the widgets. Real-time metrics pull data from various areas in Agent Desktop and are constantly updated in real-time (every few seconds) to reflect the current status of your contact center operations.
For a complete list of these statistics including definitions, see All Real-time Metrics in the Reporting Reference Guide. Real-time metrics names often have several variations depending on where they appear in Agent Desktop; the Wallboard names will be listed under the main real-time metric name. Information About Real-time Metrics, also located in the Reporting Reference Guide, provides general details about how these metrics function.
