Logstash does not transfer all CSV files to an Elasticsearch index

Hi everyone,

Background info:
I am trying to read CSV files' data and transfer it to an Elasticsearch index.

Issue:
Elasticsearch index shows only one CSV path in that specific index. I called it "rosindex". Refreshing the page at https://***.found.io:9243/rosindex/_search?pretty will show different JSON content for different CSV paths, but I don't want it it this way. I want all CSV files to show up at once in the index.

Is there anyway i can show all CSV datas at once?

Logstash.conf file:

input {
    file {
        type => ".csv"
        start_position => "beginning"
        path => "/home/kourosh/Documents/metrics/files/*.csv"
    }
}

filter {
 ....
}

output{
    elasticsearch{
        hosts => ["https://***.found.io:9243"]
        user => "..."
        password => "..."
        index => "rosindex"
        workers => 1
    }
    stdout { 
        codec => rubydebug 
    }
}

Elasticsearch index:

  "timed_out" : false,

Bump, I'm still having problems with this. Any suggestions?
