logstatsh.conf

input {
  elasticsearch {
    hosts => "XXXXXXXXX"
    index => "mon"
  }
}

output {
  elasticsearch {
    hosts => "XXXXXX"
    index => "mon"
    user => "XXXXX"
    password => "XXXXXX"

    }
}

_id在Logstash中运行管道时没有获取数据。我希望在8.9中有相同的_id数据
例如：输出2.3 V的_id值为“yyyy-mm-dd-hh-mi-ss-ms”

"hits" : [
      {
        "_index" : "mon",
        "_id" : "2017-10-23-16.41.22.548866",
        "_score" : 1.0,
        "_source" : {

输出8.9 v的_id值为“AwedmdfkgkiAkfkls”

"hits" : [

      {
        "_index" : "mon",
        "_id" : "AwedmdfkgkiAkfkls",
        "_score" : 1.0,
        "_source" : {
