I have to project in rails which have huge logs, I want to parse them in logstash and kibana, the problem is when logs do from web application logstash could not pars them but after modified them even very unused change then logstash pars them. I'm looking in logstash logs but everything is fine, I also found this issues which are completely mine but our config file is different I don't know what's wrongs could you please help me.

```auto
input {
    file {
        start_position => "beginning"
        type => "json"
        path => ["/usr/share/logstash/MPD_LOCATION/*",
                 "/usr/share/logstash/MPD_LOCATION/*/*",
                 "/usr/share/logstash/MPD_LOCATION/*/*/*",
                 "/usr/share/logstash/MPD_LOCATION/*/*/*/*",
                 "/usr/share/logstash/MPD_LOCATION/*/*/*/*/*"]
# sincedb_path => "/dev/null"
  }
}

filter {
    mutate {
        gsub => ["message","/}+({)/", "}::{"]
    }
    mutate {
        gsub => ["message","/}+( )/", "}::"]
    }
    split {
        field => "message"
        terminator => "::"
    }
    json { source => "message" }
    mutate {
        add_field => { "uuid" => "D%{driver_id}T%{created_at}" }
        rename => {
                "[location][latitude]" => "[location][lat]"
                "[location][longitude]" => "[location][lon]"
        }
        convert => {
                "[location][lat]" => "float"
                "[location][lon]" => "float"
        }
    }
}
output {
    if ([type] == "location") {
      elasticsearch {
        hosts => "http://elasticsearch:9200"
        index => "live_locations_%{+YYYY_MM_dd}"
        manage_template => true
        template => "/usr/share/logstash/Template/live_locations.json"
        template_name => "live_locations"
        document_id => "%{uuid}"
      }
    } else if ([type] == "app_info") {
      elasticsearch {
        hosts => "http://elasticsearch:9200"
        index => "app_info_%{+YYYY_MM_dd}"
        document_id => "%{uuid}"
      }
    }
    stdout {}
}
