Zipkin

Datakit 内嵌的 Zipkin Agent 用于接收，运算，分析 Zipkin Tracing 协议数据。

Zipkin 文档

配置 Zipkin Agent

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

[[inputs.zipkin]]
  pathV1 = "/api/v1/spans"
  pathV2 = "/api/v2/spans"

  ## customer_tags is a list of keys contains keys set by client code like span.SetTag(key, value)
  ## that want to send to data center. Those keys set by client code will take precedence over
  ## keys in [inputs.zipkin.tags]. DOT(.) IN KEY WILL BE REPLACED BY DASH(_) WHEN SENDING.
  # customer_tags = ["key1", "key2", ...]

  ## Keep rare tracing resources list switch.
  ## If some resources are rare enough(not presend in 1 hour), those resource will always send
  ## to data center and do not consider samplers and filters.
  # keep_rare_resource = false

  ## Ignore tracing resources map like service:[resources...].
  ## The service name is the full service name in current application.
  ## The resource list is regular expressions uses to block resource names.
  ## If you want to block some resources universally under all services, you can set the
  ## service name as "*". Note: double quotes "" cannot be omitted.
  # [inputs.zipkin.close_resource]
    # service1 = ["resource1", "resource2", ...]
    # service2 = ["resource1", "resource2", ...]
    # "*" = ["close_resource_under_all_services"]
    # ...

  ## Sampler config uses to set global sampling strategy.
  ## sampling_rate used to set global sampling rate.
  # [inputs.zipkin.sampler]
    # sampling_rate = 1.0

  # [inputs.zipkin.tags]
    # key1 = "value1"
    # key2 = "value2"
    # ...

  ## Threads config controls how many goroutines an agent cloud start to handle HTTP request.
  ## buffer is the size of jobs' buffering of worker channel.
  ## threads is the total number fo goroutines at running time.
  # [inputs.zipkin.threads]
    # buffer = 100
    # threads = 8

  ## Storage config a local storage space in hard dirver to cache trace data.
  ## path is the local file path used to cache data.
  ## capacity is total space size(MB) used to store data.
  # [inputs.zipkin.storage]
    # path = "./zipkin_storage"
    # capacity = 5120

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。
