Get current time using ruby filter in logstash

I was only able to have a similar feature as what you wanted by creating explicit created_at and updated_at fields: input { stdin { codec => json } } filter { ruby { code => "event.set('updated_date', event.get('@timestamp'))" } } output { elasticsearch { action => update document_id => "%{my_id}" upsert => '{ "document_id": "%{my_id}", "value": "%{value}", "created_at": "%{@timestamp}", "updated_at": "%{@timestamp}" }' } }
