{% raw %} Configure OpenTelemetry programmatically rather than through environment variables or command-line flags. This creates a more maintainable and standardized approach to observability. Additionally, ensure all observability components like collectors are explicitly included in your deployment configurations. Example: ```yaml # Preferred - Adding collector to Docker Compose services services: "${{ format('{0}\notel-collector', join(matrix.containers, '\n')) }}" # Avoid passing as environment variables # make OTEL=true functional-test-coverage # Not recommended ``` This approach ensures consistent observability setup across environments and makes configuration changes more traceable through source control. {% endraw %}
