Understanding widgets
Widgets are tables, graphs, pie charts, and more, made to display information collected by Observer Platform products. For widgets to have any effect, they must be put into dashboards.
Widgets are the building blocks of your dashboards. Every widget type is designed to help you better understand the traffic of your network. For example, the graph widget type could help you visualize traffic over time, while a chart widget type could display which protocols contributed most of the traffic during the report period.

Widgets show the data collected by other products. Widgets show the data collected by data sources. Data sources are your other Observer Platform products. This retrieved data, from data sources, is parsed by Apex and displayed in dashboards that include the widget. Without dashboards to operate inside, widgets will not show any data.
System widgets are available "out-of-the-box" and cannot be modified. Widgets that were created by VIAVI are available to you as system widgets. System widgets are identical in function to widgets you create on your own, but system widgets cannot be modified. As your teams become comfortable with creating their own widgets, you might develop less reliance on these. We recommend using system widgets as needed, and even exploring how the system widgets were created can aid your learning about Apex!
Widgets can be filtered. The purpose of widget filtering is to narrow the scope of reported criteria, so the end result, like a graph, is specific and easily understood by viewers. Any widget can have a filter written directly into its design. Widget filters force the widget to display only information that meets the filter.
For example, you can filter a widget so that it shows statistics from only specific applications or ports. The filter can be applied to the design of the widget itself, which creates always-filtered results when viewing that widget. You can combine a widget filter with other filtering techniques, such as filtering the dashboard or business group, to further filter your results. The widget retains its filter regardless of the dashboards it is placed into. Finally, filtering a widget will not displace or modify your underlying data.
The same widget can be put into different dashboards. Widgets can be reused by any number of dashboards. For example, if a widget is placed in one dashboard, the widget can also be put into a different dashboard. Each "instance" of a widget behaves exactly the same regardless of the dashboard, or dashboards, it was placed into. There are some exceptions, however. One example is if a dashboard or business group is being filtered, the information shown by the widget is influenced by the filter. Under these circumstances, it is possible for the same widget to display different information based on the filter of its parent dashboard or business group.
