  ## ignore_tags will work as a blacklist to prevent tags send to data center.
  ## Every value in this list is a valid string of regular expression.
  # ignore_tags = ["block1", "block2"]

  ## 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 ddtrace: It is possible to compatible OTEL Trace with DDTrace trace
  # compatible_ddtrace=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.opentelemetry.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.opentelemetry.sampler]
    # sampling_rate = 1.0

  # [inputs.opentelemetry.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.opentelemetry.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.opentelemetry.storage]
    # path = "./otel_storage"
    # capacity = 5120

  ## OTEL agent HTTP config for trace and metrics
  ## If enable set to be true, trace and metrics will be received on path respectively, by default is:
  ## trace : /otel/v1/trace
  ## metric: /otel/v1/metric
  ## and the client side should be configured properly with Datakit listening port(default: 9529)
  ## or custom HTTP request path.
  ## for example http://127.0.0.1:9529/otel/v1/trace
  ## The acceptable http_status_ok values will be 200 or 202.
  [inputs.opentelemetry.http]
   enable = true
   http_status_ok = 200
   trace_api = "/otel/v1/trace"
   metric_api = "/otel/v1/metric"

  ## OTEL agent GRPC config for trace and metrics.
  ## GRPC services for trace and metrics can be enabled respectively as setting either to be true.
  ## add is the listening on address for GRPC server.
  [inputs.opentelemetry.grpc]
   trace_enable = true
   metric_enable = true
   addr = "127.0.0.1:4317"

  ## If 'expected_headers' is well configed, then the obligation of sending certain wanted HTTP headers is on the client side,
  ## otherwise HTTP status code 400(bad request) will be provoked.
  ## Note: expected_headers will be effected on both trace and metrics if setted up.
  # [inputs.opentelemetry.expected_headers]
  # ex_version = "1.2.3"
  # ex_name = "env_resource_name"
