Question

我正在尝试绘制我在grafana中存储在elasticsearch中的数据。所有数据如下所示：

{
  "_index": "cisco-ios-xr-pfi-im-cmd-oper:interfaces-interface-briefs-interface-brief",
  "_type": "devices",
  "_id": "oPcd_mMBJueaJFICTywM",
  "_version": 1,
  "_score": null,
  "_source": {
    "keys": [
      {
        "interface-name": "Bundle-Ether23"
      }
    ],
    "content": [
      {
        "interface": "Bundle-Ether23",
        "parent-interface": "<No interface>",
        "type": "IFT_ETHERBUNDLE",
        "state": "im-state-up",
        "actual-state": "im-state-up",
        "line-state": "im-state-up",
        "actual-line-state": "im-state-up",
        "encapsulation": "ether",
        "encapsulation-type-string": "ARPA",
        "mtu": 2000,
        "sub-interface-mtu-overhead": 0,
        "l2-transport": "false",
        "bandwidth": 10000000
      }
    ],
    "node": "ncs-5508-CX",
    "timestamp": 1529004751493
  },
  "fields": {
    "timestamp": [
      "2018-06-14T19:32:31.493Z"
    ]
  },
  "sort": [
    1529004751493
  ]
}

我想绘制时间戳的图形（当我将弹性搜索添加到grafana时，它采用了时间戳字段，我将索引作为*）。

如何查询内容值？

说我想图索引：键：{键值} - ＆gt; y轴上的content.mtu。

我看到当我计算时，我得到的所有文件都与我给出的任何索引相匹配，但我似乎无法弄清楚如何得到一个值来绘制。
