無法在Grafana 2.x中從Elasticsearch Lucene查詢中繪制圖表

Question

我正在使用帶有Elasticsearchas數據源的Grafana。 在每個文檔上，我都有一個字段“ id”和“ lastmodifiedDate”。 我想顯示帶有ID相應上次修改日期的計數表。

這是我的文件：

{
        "_index": "global_search",
        "_type": "News_Item",
        "_id": "48",
        "_score": 1,
        "_source": {
          "id": "48",
          "dueDate": 1478802600000,
          "lastModifiedDate": 1478802600000,
          "whenCreatedDate": 1477506600000,
          "ownerEmail": "abc@gmail.com",
          "owner": {
            "firstname": "ABC",
            "lastname": "Kumar",
            "email": "abc@gmail.com"
          },
          "subject": "USA','According to NBCDFW.com, an explosion at a silicon plant ",
          "status": "NEW",
          "updatedby": "ABC Kumar",
          "content": "Text data"
        }
      },
      {
        "_index": "global_search",
        "_type": "News_Item",
        "_id": "26",
        "_score": 1,
        "_source": {
          "id": "26",
          "dueDate": 1477679400000,
          "lastModifiedDate": 1477679400000,
          "whenCreatedDate": 1477506600000,
          "researchTitle": "Flash Floods Hit Parts of Southern France",
          "ownerEmail": "xyz@gmail.com",
          "owner": {
            "firstname": "XYZ",
            "lastname": "Kumar",
            "email": "xyz@gmail.com"
          },
          "subject": "Flash Floods Hit Parts of Southern France",
          "status": "MONITORING",
          "updatedby": "XYZ",
          "content": "Text2 data"
        }
      }

問：如何繪制具有ID的依日期的表格？Lucene查詢要繪制表格的確切方式是什么？

Answer 1

您可以使用以下查詢參數獲取它：

Metric:
  Count
Group by:
  type: Date Histogram
  field: lastModifiedDate

查詢字段可以留為空白。
