There are more than 600 pieces of data in my log, but only more than 300 pieces are written to elasticsearch.
Does anyone know the reason for this?
This is my configuration
input {

file {
    path => ["／usr/local/20170730.log"]
    type => "log_test_events"
    tags => ["log_tes_events"]
    start_position => "beginning"
    sincedb_path => "/data/logstash/sincedb/test.sincedb"
    codec => "json"
    close_older => "86400"
    #1 day
    ignore_older => "86400"
}
beats{port => 5044}

}
filter {

urldecode {
    all_fields => true
}

}

output{

   elasticsearch {
      hosts  => "localhost:9200"
      index  => "logstash_%{event_date}"
}

stdout { codec => json }
}
