OTel Config Examples

An OpenTelemetry receiver ingests telemetry data (metrics, logs, traces) in specific formats from agents or services and forwards it through a processing pipeline. A full raw configuration involves manually defining the entire pipeline—receivers, processors, and exporters—providing full control over data flow, enrichment, and output. Below are some example configuration templates to help you get started.

OTel Full Raw Configuration Examples

Below are full raw configuration examples for OpenTelemetry Collector deployments, covering Windows, Linux, and macOS environments. These examples demonstrate end-to-end pipeline setups, including receivers, processors, and exporters, tailored for each operating system.

Windows

Use otlp with TLS (if required) not otlphttp since it’s more efficient.

receivers:
  windowseventlog/security:
    channel: security

processors:
  attributes:
    actions:
      - key: environment
        value: "production"

exporters:

      initial_interval: 5s
      max_elapsed_time: 300s
      max_interval: 30s
    timeout: 30s
    tls:
      insecure: true
