Hello,  
I am trying to read csv file with logstash but logstash reads only firs 10 rows. Where could be a problem?

Structure of my CSV file:  
500;message 1  
200;message 2  
500;message 1  
200;message 2  
500;message 1  
200;message 2  
500;message 1  
200;message 2  
500;message 1  
200;message 2  
500;message 1  
200;message 2  
500;message 1  
200;message 2

my logstash.conf

```
input {
  file {
    path => ["/usr/share/logstash/data1/*"]
    start_position => "beginning"
    sincedb_path => "/dev/null"
  }
}

filter {
  csv {
    separator => ";"
    columns => ["statuscode", "message"]
  }
}

output {
  elasticsearch {
    hosts => ["http://host.docker.internal:9200"]
    index => "mylog"
  }
}

```

When I open [http://localhost:9200/mylog/\_search?pretty](http://localhost:9200/mylog/_search?pretty) I see only first 10 rows of my file.

Thanks for your detailed input, configuration and query commands used to get your desired output. It makes it really easier to troubleshoot 🙂

Your issue is related to the **elasticsearch query** : if the output "size" is not specified, **the default is 10 results**.

It is better explained in this response: [Get query is showing only 10 results while searching for a particular data - #2 by ogtool](https://discuss.elastic.co/t/get-query-is-showing-only-10-results-while-searching-for-a-particular-data/88187/2)
