Hi Folks,
is it possible in Logstash to rename fields (received as json) based on a dictionary File? Basically the same function like the translate filter does, but not for values but for field names.
Background: At the moment our applications are sending there logs in json format to logstash. Problem is that the applications don´t use a unified fieldname set, some fieldnames are the same some not.
We´re now want to implement ECS to harmonize all Fields over all different Logtypes.
Because it would now take a very long time until all teams had converted all their applications to ecs-compliant logging, we would like to rename the old field names in logstash to the new ecs field names. For this we would like to use a dictionary just like the translate filter does.
Is this possible within Logstash?
regards,
Frank
