使用 ILM 运行降采样

编辑

这是一个简化的示例,让您可以快速了解 降采样 如何作为 ILM 策略的一部分工作,以减少采样指标集的存储大小。该示例使用典型的 Kubernetes 集群监控数据。要使用 ILM 测试降采样,请按照以下步骤操作

先决条件

编辑

请参阅时间序列数据流先决条件

在运行此示例之前,您可能需要尝试手动运行降采样示例。

创建索引生命周期策略

编辑

为您的时间序列数据创建 ILM 策略。虽然不是必需的,但建议使用 ILM 策略来自动化管理您的时间序列数据流索引。

要启用降采样,请添加一个 降采样操作,并将 fixed_interval 设置为您要聚合原始时间序列数据的降采样间隔。

在此示例中,为 hot 阶段配置了 ILM 策略。降采样发生在索引滚动之后,并且在 索引时间序列结束时间 过期后进行,因为源索引在此之前仍有望接收主要写入。在 索引的结束时间 过期之前,索引生命周期管理将不会继续执行任何期望索引不再接收写入的操作。在继续之前等待结束时间的索引生命周期管理操作包括: - 删除 - 降采样 - 强制合并 - 只读 - 可搜索快照 - 收缩

创建索引模板

编辑

这将为基本数据流创建一个索引模板。有关索引模板的可用参数的详细描述,请参阅设置时间序列数据流

为简单起见,在时间序列映射中,所有 time_series_metric 参数都设置为类型 gauge,但也可以使用 counter 指标类型。time_series_metric 值决定了在降采样期间使用的统计表示类型。

索引模板包含一组静态的时间序列维度hostnamespacenodepod。时间序列维度不会被降采样过程更改。

摄取时间序列数据

使用批量 API 请求自动创建您的 TSDS 并索引一组十个文档。

重要提示: 在运行此批量请求之前,您需要将时间戳更新为当前时间后的三到五个小时内。也就是说,搜索 2022-06-21T15 并替换为您的当前日期,并将小时调整为当前时间加三个小时。

现在您已经创建了数据流并向其中添加了文档,请检查以确认新索引的当前状态。

resp = client.indices.get_data_stream()
print(resp)
response = client.indices.get_data_stream
puts response
const response = await client.indices.getDataStream();
console.log(response);
GET _data_stream

如果尚未应用 ILM 策略,则您的结果将如下所示。请注意原始 index_name.ds-datastream-<timestamp>-000001

{
  "data_streams": [
    {
      "name": "datastream",
      "timestamp_field": {
        "name": "@timestamp"
      },
      "indices": [
        {
          "index_name": ".ds-datastream-2022.08.26-000001",
          "index_uuid": "5g-3HrfETga-5EFKBM6R-w"
        },
        {
          "index_name": ".ds-datastream-2022.08.26-000002",
          "index_uuid": "o0yRTdhWSo2pY8XMvfwy7Q"
        }
      ],
      "generation": 2,
      "status": "GREEN",
      "template": "datastream_template",
      "ilm_policy": "datastream_policy",
      "hidden": false,
      "system": false,
      "allow_custom_routing": false,
      "replicated": false,
      "rollover_on_write": false,
      "time_series": {
        "temporal_ranges": [
          {
            "start": "2022-08-26T13:29:07.000Z",
            "end": "2022-08-26T19:29:07.000Z"
          }
        ]
      }
    }
  ]
}

接下来,运行搜索查询

resp = client.search(
    index="datastream",
)
print(resp)
response = client.search(
  index: 'datastream'
)
puts response
const response = await client.search({
  index: "datastream",
});
console.log(response);
GET datastream/_search

该查询返回您新添加的十个文档。

{
  "took": 17,
  "timed_out": false,
  "_shards": {
    "total": 4,
    "successful": 4,
    "skipped": 0,
    "failed": 0
  },
  "hits": {
    "total": {
      "value": 10,
      "relation": "eq"
    },
...

默认情况下,索引生命周期管理每十分钟检查一次符合策略条件的索引。等待大约十分钟(也许可以泡一杯咖啡或茶 ☕),然后重新运行 GET _data_stream 请求。

resp = client.indices.get_data_stream()
print(resp)
response = client.indices.get_data_stream
puts response
const response = await client.indices.getDataStream();
console.log(response);
GET _data_stream

在 ILM 策略生效后,原始的 .ds-datastream-2022.08.26-000001 索引将替换为一个新的降采样索引,在本例中为 downsample-6tkn-.ds-datastream-2022.08.26-000001

{
  "data_streams": [
    {
      "name": "datastream",
      "timestamp_field": {
        "name": "@timestamp"
      },
      "indices": [
        {
          "index_name": "downsample-6tkn-.ds-datastream-2022.08.26-000001",
          "index_uuid": "qRane1fQQDCNgKQhXmTIvg"
        },
        {
          "index_name": ".ds-datastream-2022.08.26-000002",
          "index_uuid": "o0yRTdhWSo2pY8XMvfwy7Q"
        }
      ],
...

在数据流上运行搜索查询(请注意,在查询降采样索引时,需要注意一些细微之处)。

resp = client.search(
    index="datastream",
)
print(resp)
response = client.search(
  index: 'datastream'
)
puts response
const response = await client.search({
  index: "datastream",
});
console.log(response);
GET datastream/_search

新的降采样索引仅包含一个文档,该文档包括基于原始采样指标的 minmaxsumvalue_count 统计信息。

使用数据流统计 API 获取数据流的统计信息,包括存储大小。

resp = client.indices.data_streams_stats(
    name="datastream",
    human=True,
)
print(resp)
response = client.indices.data_streams_stats(
  name: 'datastream',
  human: true
)
puts response
const response = await client.indices.dataStreamsStats({
  name: "datastream",
  human: "true",
});
console.log(response);
GET /_data_stream/datastream/_stats?human=true
{
  "_shards": {
    "total": 4,
    "successful": 4,
    "failed": 0
  },

    }
  ]
}

此示例演示了降采样如何作为 ILM 策略的一部分工作,以减少指标数据的存储大小,因为指标数据变得不再是最新的,并且查询频率较低。

您也可以尝试我们的手动运行降采样示例,以了解降采样如何在 ILM 策略之外工作。
