@metadata is missing in Logstash
edit@metadata is missing in Logstash
editLogstash outputs remove @metadata
fields automatically. Therefore, if Logstash instances are chained directly or via some message
queue (for example, Redis or Kafka), the @metadata
field will not be available in the final Logstash instance.
To preserve @metadata
fields, use the Logstash mutate filter with the rename setting to rename the fields to
non-internal fields.
