App Sources
The App sources enables a generic definition of the Apps logs/folders/servers sources which will be added to all used search queries in the dashboard's gadgetswidgets.
For example if the App's dashboards should refer to servers x, y, z then it is possible to specify this directly in each gadgetwidget's search query. Alternatively, it is possible to use generic queries in the gadgets widgets and specify the list of sources in the App Sources section.

XpoLog Apps support definition of multiple export schedulers. Using more than one export scheduler allows a configuration of a specific date range for each scheduled export. For example it is possible to configure on the same App an export scheduler once a week on the last week and another scheduler once a day on the last day - the result will be a daily export presenting the last day and a weekly export presenting the last week of the specified dashboards in this App.
