Create a collector

Requirements

• go

Step by step

• Create a file called mainifest.yaml with contents

dist:
  name: otelcol-dev
  description: Basic OTel Collector distribution for Developers
  output_path: ./otelcol-dev

exporters:
  - gomod:
      go.opentelemetry.io/collector/exporter/debugexporter v0.119.0
  - gomod:
      go.opentelemetry.io/collector/exporter/otlphttpexporter v0.119.0

processors:
  - gomod:
      go.opentelemetry.io/collector/processor/batchprocessor v0.119.0

receivers:
  - gomod: 
      github.com/open-telemetry/opentelemetry-collector-contrib/receiver/netflowreceiver v0.119.0

• install ocb

curl --proto '=https' --tlsv1.2 -fL -o ocb \
https://github.com/open-telemetry/opentelemetry-collector-releases/releases/download/cmd%2Fbuilder%2Fv0.119.0/ocb_0.119.0_linux_amd64
chmod +x ocb

• build the collector

./ocb --config manifest.yaml

• create the config.yaml file

receivers:
  netflow:
    hostname: "0.0.0.0"
    scheme: netflow
    port: 2055
    sockets: 16
    workers: 32

processors:
  batch:
    send_batch_size: 30 
    timeout: 30s

exporters:
  debug:
  otlphttp:
    endpoint: https://<environment>.live.dynatrace.com/api/v2/otlp
    headers: 
      Authorization: "Api-Token <dynatrace_ingest_logs_token>"

service:
  pipelines:
    logs:
      receivers: [netflow]
      processors: [batch]
      exporters: [debug, otlphttp]
  telemetry:
    logs:
      level: debug

• run the collector

./otelcol-dev/otelcol-dev --config config.yaml
