    logstash code
    input {
      http_poller {
        urls => {
         urlname =>"http://.."
         }
        }
        request_timeout => 60
        schedule => {every=>"20s"}
        codec => "line"
      }
    }


output {
elasticsearch{
hosts=>{"localhost:9200"}
index =>"logstash_http_poller"
}
  stdout {
    codec => rubydebug
  }
}

command from powershell logstash -f logstash_http_poller.conf

Answer 1

Your elasticsearch output is wrong, you don't need curly braces around the hosts:

elasticsearch {
    hosts => "localhost:9200"                     <-- change this
    index => "logstash_http_poller"
}

Answer 2

input {
  http_poller {
    urls => 
    { 
    test1 => "rest api url"
    }
    request_timeout => 60
    # Supports "cron", "every", "at" and "in" schedules by rufus scheduler
    schedule => { cron => "* * * * * UTC"}
    codec => "json"
    # A hash of request metadata info (timing, response headers, etc.) will be sent here
    metadata_target => "http_poller_metadata"
  }
}

output {
  stdout {
    codec => rubydebug
  }
}
