Hello,
I am trying to copy the value of @timestamp to new field timestamp keeping the same format.
Is that possible ? Do you have any suggestion ?
Thank you.
Mustapha

Hello,
Thanks for the reply.

Thank you.

I also tried using the copy filter, but that fails silently. mutate { copy =\> { "%{@timestamp}" =\> "logstash\_intake\_timestamp" } } I tried this, but it also caused exceptions (I don't have the stack trace right now, but I could get it if it would help the investigation). mutate { copy =\> { "@timestamp" =\> "logstash\_intake\_ti…
