Index name removes date

[John_McAfee1 (John Mc Afee)]

Hello,

I am using Logstash 7.2.0 and have encountered an issue with naming my index with a timestamp. An index is created in Logstash, but it doesn't contain the date. It only contains the characters before the dash. For example, if the index is named performance-%{YYYY.MM.dd} the index created in Elasticsearch is only performance- and the date is missing.

My output config is:
output {
stdout { codec => rubydebug }
elasticsearch {
hosts => ["10.x.x.x:9200"]
user => "user"
password => "password"
action => "update"
doc_as_upsert => true
document_id => "%{uuid}"
index => "test-%{+YYYY.MM.dd}"
}
}

I also tried lowercase yyyy thinking maybe the syntx is incorrect. but it did not work either.

Thanks,

John

My reading of the code is that that means you have deleted the @timestamp field.

Thank you! Not sure why I did that, but that was definitely the problem.
