I want to make it from timestams to timestamp like one message and then parsing in filter, my code bellow. but there is no data in elastic even without filtering. Could you give any advise?

My guess-work is that input can't understand what to do with this beginnig part of log:
Trace file /gh/app
Oracle Database 11g Enterprise Edition Release 11.2.0.4.0 - 64bit Production
With the Partitioning option
ORACLE_HOME

Node name: kz-cdb
Release: 5.11

How to say input to skip this part, because when i remove this part everything works fine?

input {

    file {
        path => "/home/ubuntu/ora_24994.trc"
        start_position => "beginning"
        codec => multiline {
          pattern => "^\*** %{TIMESTAMP_ISO8601}"
        negate => "true"
        what => "previous"
      }
    }
    }

    filter {
    }




    output {

        elasticsearch {
          hosts => ["localhost:9200"]
             index => "cdb_logs2"
        }
    }

I solved with drop in filter part
