网络拨测



该采集器是网络拨测结果数据采集,所有拨测产生的数据,上报观测云。

配置

私有拨测节点部署

私有拨测节点部署,需在 观测云页面创建私有拨测节点。创建完成后,将页面上相关信息填入 conf.d/network/dialtesting.conf 即可:

进入 DataKit 安装目录下的 conf.d/network 目录,复制 dialtesting.conf.sample 并命名为 dialtesting.conf。示例如下:

[[inputs.dialtesting]]
  # We can also configure a JSON path like "file:///your/dir/json-file-name"
  server = "https://dflux-dial.guance.com"

  # [require] node ID
  region_id = "default"

  # if server are dflux-dial.guance.com, ak/sk required
  ak = ""
  sk = ""

  # The interval to pull the tasks.
  pull_interval = "1m"

  # The timeout for the HTTP request.
  time_out = "30s"

  # The number of the workers.
  workers = 6

  # Collect related metric when job execution time error interval is larger than task_exec_time_interval
  task_exec_time_interval = "5s"

  # Stop the task when the task failed to send data to dataway over max_send_fail_count.
  max_send_fail_count = 16

  # The max number of jobs sending data to dataway in parallel. Default 10.
  max_job_number = 10

  # The max number of job chan. Default 1000.
  max_job_chan_number = 1000

  # Custom tags.
  [inputs.dialtesting.tags]
  # some_tag = "some_value"
  # more_tag = "some_other_value"
  # ...

配置好后,重启 DataKit 即可。

目前可以通过 ConfigMap 方式注入采集器配置来开启采集器。


Attention

目前只有 Linux 的拨测节点才支持「路由跟踪」,跟踪数据会保存在相关指标的 traceroute 字段中。

指标

拨测采集器会暴露 Prometheus 指标,如果需要上报这些指标至观测云,可以通过 DataKit 采集器 进行采集,相关配置参考如下:

[[inputs.dk]]
  ......

  metric_name_filter = [

  ### others...

  ### dialtesting
  "datakit_dialtesting_.*",

  ]

  ......

日志

以下所有数据采集,默认会追加名为 host 的全局 tag(tag 值为 DataKit 所在主机名),也可以在配置中通过 [[inputs.dialtesting.tags]] 另择 host 来命名。

traceroute 字段描述

traceroute 是「路由跟踪」数据的 JSON 文本,整个数据是一个数组对象,对象中的每个数组元素记录了一次路由探测的相关情况,示例如下:

[
    {
        "total": 2,
        "failed": 0,
        "loss": 0,
        "avg_cost": 12700395,
        "min_cost": 11902041,
        "max_cost": 13498750,
        "std_cost": 1129043,
        "items": [
            {
