Ingesting Telegraf metrics

If you're using Telegrafopen in new window 1.20.0+ to collect metrics, you can ingest them to Uptrace using the OpenTelemetryopen in new window output plugin:

[[outputs.opentelemetry]]
  service_address = "otlp.uptrace.dev:4317"

  [outputs.opentelemetry.headers]
  uptrace-dsn = "https://FIXME@api.uptrace.dev?grpc=4317"

  ## Additional OpenTelemetry resource attributes
  # [outputs.opentelemetry.attributes]
  # "service.name" = "demo"

[[outputs.opentelemetry]]
  service_address = "localhost:14317"

  ## Optional TLS Config.
  ##
  ## Root certificates for verifying server certificates encoded in PEM format.
  # tls_ca = "/etc/telegraf/ca.pem"
  ## The public and private key pairs for the client encoded in PEM format.
  ## May contain intermediate certificates.
  # tls_cert = "/etc/telegraf/cert.pem"
  # tls_key = "/etc/telegraf/key.pem"
  ## Use TLS, but skip TLS chain and host verification.
  # insecure_skip_verify = false
  ## Send the specified TLS server name via SNI.
  # tls_server_name = "foo.example.com"

  [outputs.opentelemetry.headers]
  uptrace-dsn = "http://project2_secret_token@localhost:14318?grpc=14317"

  ## Additional OpenTelemetry resource attributes
  # [outputs.opentelemetry.attributes]
  # "service.name" = "demo"
