Graylog supports a wide variety of widgets that let you quickly visualize data from your logs. Adding search result information is easy and quick. Once you add widgets to the dashboard, you can rearrange and configure those widgets to customize the look.
Advanced data aggregation allows you to combine different types of data in a single chart so you can perform multiple aggregations on the same field and/or present different types of aggregations on different fields in the same chart. This enables a pivot table-like experience.
You can also add widgets from stream search results. Every widget you add this way will always be bound to streams. The Graylog streams are a mechanism to route messages into categories in real time while they are processed. You define rules that instruct Graylog which message to route into which streams.
