elasticsearch 基巴纳。通过匹配来自其他筛选的值筛选记录

我在kibana看到这样的消息持续了5秒钟：

Date, Message, TraceId

Dec 10, 2020 @ 10:49:50.285 New request start http://somehost/path1   7ec708ab153e644f
Dec 10, 2020 @ 10:49:51.179 New request end http://somehost/path1     7ec708ab153e644f
Dec 10, 2020 @ 10:49:52.285 New request start http://somehost/path2   1e090982aeb026a3
Dec 10, 2020 @ 10:49:54.285 New request start http://somehost/path3   b880dfa9c4fd39ad
Dec 10, 2020 @ 10:49:53.179 New request end http://somehost/path3     b880dfa9c4fd39ad
Dec 10, 2020 @ 10:49:54.349 New request start http://somehost/path4   65184024b220dd0c

我如何筛选记录以仅查看“新请求开始”行，这些行没有通过“traceId”匹配的相应“新请求结束”

例如，对于上面的行，我希望看到结果：

Dec 10, 2020 @ 10:49:52.285 New request start http://somehost/path2   1e090982aeb026a3
Dec 10, 2020 @ 10:49:54.349 New request start http://somehost/path4   65184024b220dd0c

你可以

按traceID分组

仅获取一个按日期排序的结果，或在“消息”字段中使用“开始”筛选1个结果

以下是一些示例：

{
  "size": 0,
  "aggs": {
    "group_by_trace": {
      "terms": {
        "field": "TraceId.keyword",
        "size": 10,
        "min_doc_count": 2
      },
      "aggs": {
        "startt_request": {
        "top_hits": {
          "sort": [
            {
              "date": {
                "order": "asc"
              }
            }
          ],
          "_source": {
            "includes": [
              "date",
              "message",
              "TraceId"
            ]
          },
          "size": 1
        }
        }
      }
    }
  }
}

答复如下：

或者更好，您可以使用过滤器：

GET /_search?filter_path=aggregations.group_by_trace.buckets.start_messages.buckets.start.start_request.hits.hits
{
  "size": 0,
  "aggs": {
    "group_by_trace": {
      "terms": {
        "field": "TraceId.keyword",
        "size": 10,
        "min_doc_count": 2
      },
      "aggs": {
        "start_messages": {
          "filters": {
            "filters": {
              "start": {
                "match": {
                  "message": "start"
                }
              }
            }
          },
          "aggs": {
            "start_request": {
              "top_hits": {
                "_source": {
                  "includes": [
                    "date",
                    "message",
                    "TraceId"
                  ]
                },
                "size": 1
              }
            }
          }
        }
      }
    }
