hi,
i want to add a new field in my config filebeat and put in it the @timestamp value :
fields:
harvest\_timestamp: @timestamp
but it doesn't work ...
my goal, at the end, is to delete the field @timestamp and just keep the new field 'harvest\_timetamp'. Thus, my logstash shipper, output in my config, will create his own @timestamp... and i will know :
1 - the harvest timestamp
2 - the shipping timestamp
A solution exists please ? ty

you can not rename fields in filebeat directly. You have to do this kind of processing in logstash, but no idea if you can overwrite the `@timestamp` in logstash.

the timestamp is not set by output plugin, but by input plugins. Using ruby or mutate filter you can try to store `@timestamp` into `harvest_timestamp` and try to overwrite timestamp. Never tried, but with ruby filter you can try
```auto
ruby {
code => 'event["[@timestamp]"] = Time.now'
}
```
Regarding questions about event processing in logstash, have a look at the logstash forum.
