Logstash无法在elasticsearch中为metricbeat文件输出创建索引

Question

我试图通过logstash摄取metricbeat文件输出，但logstash没有在elasticsearch中创建任何索引。下面是我的logstash .conf文件

  input {
          file {
            type => "my-metricbeat"
            path => ["C:/tmp/metricbeat/metric*"]
            codec => "json"
            start_position => beginning
            sincedb_path => "/dev/null"
          }
         }
        output {
          if([type] == "my-metricbeat") {
              elasticsearch {
                hosts => "http://localhost:9200"
                index => "metricbeat-test-%{+YYYY.MM.dd}"
              }
}
      stdout { codec => rubydebug }
         }

ELK版本为5.2.1
