move operator

The move operator moves (or renames) a field from one location to another.

Configuration Fields

Field Default Description
id move A unique identifier for the operator.
output Next in pipeline The connected operator(s) that will receive all outbound entries.
from required The field from which the value will be moved.
to required The field to which the value will be moved.
on_error send The behavior of the operator if it encounters an error. See on_error.
if An expression that, when set, will be evaluated to determine whether this operator should be used for the given entry. This allows you to do easy conditional parsing without branching logic with routers.
