How to add new line in between string field

Elastic Stack Logstash
1

Hi,

Added the below configuration in logstash

mutate {

add_field => ["temp", "Adapter Name: %{adaptername}
 			Records Imported: %{records}
 			Records Failed: %{[failedrecords][1]}  "]

i would like to display the text like below

Adapter Name: ad1
Records Read:10
Records Failed: 10

each in new line.

Please let me know the solution. Thanks you for the help!

Any luck with this? I'm trying to format a string being sent as part of the HTTP output plugin, and need to insert newlines into a string built from different fields of my incoming log.
