Mutate filter replace - please clarify the documentation

This is the info given in the docs:

Replace a field with a new value. The new value can include %{foo} strings to help you build a new value from other parts of the event.

This first sentence is highly ambiguous.

Does this either means:

  1. Replace the value of a field with a new value
  2. Change the name of a field into another name (i.e. "a new value")
2
  1. Replace the value of a field with a new value

Yes.

Feel free to submit a patch to the documentation.

I will when I find out how (I will look :wink: )
