DDTrace

[[inputs.ddtrace]]
  ## DDTrace Agent endpoints register by version respectively.
  ## Endpoints can be skipped listen by remove them from the list.
  ## NOTE: DO NOT EDIT.
  endpoints = ["/v0.3/traces", "/v0.4/traces", "/v0.5/traces"]

  ## customer_tags will work as a whitelist to prevent tags send to data center.
  ## All . will replace to _ ,like this :
  ## "project.name" to send to GuanCe center is "project_name"
  # customer_tags = ["sink_project", "custom_dd_tag"]

  ## 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

  ## By default every error presents in span will be send to data center and omit any filters or
  ## sampler. If you want to get rid of some error status, you can set the error status list here.
  # omit_err_status = ["404"]

  ## compatible otel: It is possible to compatible OTEL Trace with DDTrace trace.
  ## make span_id and parent_id to hex encoding.
  # compatible_otel=true

  ##  It is possible to compatible B3/B3Multi TraceID with DDTrace.
  # trace_id_64_bit_hex=true

  ## When true, the tracer generates 128 bit Trace IDs, 
  ## and encodes Trace IDs as 32 lowercase hexadecimal characters with zero padding.
  ## default is true.
  # trace_128_bit_id = true

  ## delete trace message
  # del_message = true

  ## max spans limit on each trace. default 100000 or set to -1 to remove this limit.
  # trace_max_spans = 100000

  ## max trace body(Content-Length) limit. default 32MiB or set to -1 to remove this limit.
  # max_trace_body_mb = 32

  ## 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.ddtrace.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.ddtrace.sampler]
  #   sampling_rate = 1.0

  # [inputs.ddtrace.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.ddtrace.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.ddtrace.storage]
  #   path = "./ddtrace_storage"
  #   capacity = 5120
