You can open a field viewer as a callout from a dependency map or as a standalone visualization from the Admin menu.
When you open a field viewer from a dependency map (as shown in Opening Field Viewers), the viewer is populated automatically based on the log source, transformation, or dimension that you right-click. For a log source or a transformation, the fields in the viewer are inputs or outputs of the log source or transformation. For a dimension, the fields are inputs of the dimension. You can add and remove fields as desired.
When you open a field viewer as a standalone visualization, you can create a Log Processing Field Viewer or a Transformation Field Viewer. The viewer is blank, and you must add the desired fields to the viewer. For a Log Processing Field Viewer, you can add fields from the Log Processing.cfg file or any Log Processing dataset include file. For a Transformation Field Viewer, you can add fields from the Transformation.cfg file or any Transformation dataset include file.
For more information about configuration and include files, see the Dataset Configuration Guide.
To add a field to a field viewer
Right-click within the field viewer and click Fields > < field name> > < instance>.
Right-click within an existing column in the field viewer and click Fields > < field name> > < instance>.
Field name refers to the field’s name, and instance refers to where in the dataset configuration the field is used, such as a dataset processing stage or a transformation. Some fields are used in multiple places within the dataset configuration (for example, a field can be modified by multiple transformations), so you must select which instance of the field to add to your field viewer.
In the list of available fields, an X appears to the left of any field already displayed in the viewer.
