#Go Auto-instrumentation

The Go auto-instrumentation enables automatic telemetry collection for Go applications by leveraging eBPF (Extended Berkeley Packet Filter) technology. This approach instruments Go applications at runtime without requiring code modifications or recompilation.

The Operator injects the OpenTelemetry Go auto-instrumentation components into Go application containers, using eBPF to capture function calls, HTTP requests, and other telemetry data. This provides observability for Go applications with minimal performance overhead.

#Enabling Go Instrumentation

To enable auto-instrumentation for Go applications, annotate your pod or namespace:

apiVersion: v1
kind: Pod
metadata:
  name: go-app
  annotations:
    instrumentation.opentelemetry.io/inject-go: "true"
spec:
  containers:
  - name: app
    image: mygoapp:latest

The Operator will automatically inject the instrumentation components when the pod is created.
