filebeat version: filebeat-6.2.3
kafka version: 0.10.2.1
filebeat.yml as follows:
filebeat.prospectors:
- type: log
enabled: ture
paths:
- /opt/filebeat/test.log
fields:
log\_topic: test
tag: bdu
output.kafka:
hosts: ["kafka1", "kafka2", "kafka3"]
topic: '%{[fields.log\_topic]}'
required\_ack: 1
It works perfect, but I have a requirement for changing the default @timestamp format (ISO 8601)
from: "@timestamp": "2018-04-12T10:58:01.787Z"
to: "@timestamp": "2018-04-12T18:58:01.787+08:00"
and I found in the /var/lib/filebeat/registry
the timestamp is exactly the format I need
is it possible to get the timestamp format in /var/lib/filebeat/registry ?
is there any other solution like getting the local time in fields ?

Have a look at [https://www.elastic.co/guide/en/logstash/current/plugins-filters-date.html](https://www.elastic.co/guide/en/logstash/current/plugins-filters-date.html)
date {
match =\> ["@timestamp", "YYYY-MM-ddddTHH:mm:ssZZ"]
}
or something like this could work.
You need some testing. Also i wouldn't quite recommend messing with timestamp itself, not sure how kibana/elastic might be affected.Try to create a second field "custom\_date"(?) and test on that.
Edit: My bad you are not using logstash, you can't use this approach unless you add logstash in your stack.

Thanks for the respond
So is it possible to have a field like this:
fields:
timestamp: {local host time}
Cause I haven’t figured out what variable to deal with that
