The timer job fetches all the key technical metrics about the SharePoint farm infrastructure using SharePoint object model and WMI (Windows Management Instrumentation). It’s frequency can be adjusted based on specific administrative needs. The timer job creates a SharePoint list that is linked to a Visio diagram.
