source_field [string]

The source field of the string before being split, if not configured, the default is raw_message

target_field [string]

target_field can specify the location where multiple split fields are added to the Event. If it is not configured, the default is _root_ , that is, all split fields will be added to the top level of the Event. If a specific field is specified, the divided field will be added to the next level of this field.

fields [list]

In the split field name list, specify the field names of each character string after splitting in order. If the length of the fields is greater than the length of the separation result, the extra fields are assigned null characters.
