OTLP Integration Requirements

Confirm that your OpenTelemetry Collector server meets the following configuration requirements:

Transport protocol

The OpenTelemetry Collector server should be configured to allow the following OTLP receiver protocols:

  • HTTP - for unencrypted connections.
  • HTTPS - for encrypted connections. Certificate validation and mutual TLS are not supported.
  • gRPC - for unencrypted gRPC connections.
  • gRPC + TLS - for encrypted gRPC connections. Certificate validation and mutual TLS are not supported.

OTLP protocol

The server should expose the OTLP receiver.

The forwarder produces an OTLP protocol ExportMetricsServiceRequest message with the following restrictions:

  • every metric is mapped to Gauge.
  • unit is set to 1(no unit).
  • the ResourceMetrics fields for SchemaUrl and Resource are empty.
  • the InstrumentationLibraryMetric fields for InstrumentationLibrary and SchemaUrl are empty.

Authentication

Authentication is currently not supported.

Example configuration for OpenTelemetry Collector

The following example configuration for OpenTelemetry Collector can receive OTLP on HTTP and HTTPS endpoints and forward it to DataDog:

receivers:
  otlp/https:
    protocols:
      http:
        endpoint: "0.0.0.0:4318"
        tls_settings:
          cert_file: /etc/otel/server.crt
          key_file: /etc/otel/server.key
  otlp/http:
    protocols:
      http:
        endpoint: "0.0.0.0:4319"
  otlp/grpc_tls:
    protocols:
      grpc:
        endpoint: "0.0.0.0:4418"
        tls_settings:
          cert_file: /etc/otel/server.crt
          key_file: /etc/otel/server.key
  otlp/grpc:
    protocols:
      grpc:
        endpoint: "0.0.0.0:4419"
exporters:
    datadog:
        api:
          key: key
service:
  pipelines:
    metrics/1:
      receivers: [otlp/http, otlp/https, otlp/grpc_tls, otlp/grpc]
      exporters: [datadog]

Add an OTLP Integration

Take the following steps to create an integration for OpenTelemetry Collector:

  1. Open the F5 NGINX Controller user interface and log in.

  2. Select the NGINX Controller menu icon, then select Platform.

  3. On the Platform menu, select Integrations.

  4. On the Integrations menu, select Create Integration.

  5. Add a name.

  6. (Optional) Add a display name.

  7. (Optional) Add a description.

  8. (Optional) Add tags.

  9. In the Integration Type list, select GENERIC_INTEGRATION.

  10. In the Endpoint URI box, add the one of HTTP, HTTPS, gRPC or gRPC+TLS endpoint for your OpenTelemetry Collector. This is the same address that's configured in the OpenTelemetry Collector config in the receivers section. See the [example config]({{< ref "/controller/platform/integrations/otlp-integration.md#example-configuration-for-opentelemetry-collector" >}}):

    • HTTP endpoint should be http://collector_ip:4319
    • HTTPS endpoint should be https://collector_ip:4318
    • gRPC endpoint should be tcp://collector_ip:4419
    • gRPC with TLS endpoint should be tcp+tls://collector_ip:4418

  11. In the Credential Type list, select UNAUTHENTICATED (at this time we do not support any authentication methods).

  12. Select Submit.
