OTLP (OpenTelemetry Protocol) enables modern, standards-based telemetry with Instana for traces and metrics. The official IBM Instana documentation explains that enabling OTLP support should be done during installation or upgrade viaHelm, using either values set in a YAML file or via the --set command line argument. This method is described as, "To enable OTLP, use Helm with the provided chart and set OTLP values in your values.yaml or with the --set flag." Helm automation allows administrators to easily manage, update, and version-control agent and collector configuration at scale—especially in Kubernetes environments. It is favored because it is compatible with Instana’s operator and dynamic config approaches. Manual edits in settings.hcl or params.yaml are not recommended or officially documented for enabling OTLP streams. Multiple tracers relate to instrumentation and are not for enabling the protocol itself. Using Helm provides a streamlined, repeatable and supported approach – per IBM Instana deployment best practices.
