Using the admin interface to build a field
Taking our pattern from the previous example, we can build the configuration
to "wire up" this extract.
First, click on Manager in the upper-right corner. The Fields section contains
everything, funnily enough, about fields.
There are a number of different things you can do with fields via configuration,
but for now, we're interested in Field extractions .
After clicking on Add new to the right of Field extractions , or on the New button
after clicking on Field extractions , we are presented with the interface for creating
a new field.
