Hey @aliraxa

Do you have a pipeline or extract configured. How are you send this data?

We don’t have any pipeline configured or any extractor related to that. we have 2 input one for syslog-ng and one for logstash.syslog-ng send show the logs correctly but we have issue in logstash logs it showing duplicate entries in source field.

hey @aliraxa

Can you share you logstash pipe? Ensure you hide you personal info if you do.
