OpenTelemetry Traces Integration

Helm Installation

These instructions install the trace collector in daemonset mode.

For additional modes and more configuration options, see OpenTelemetry documentation for OpenTelemetry Collector Chart.

  1. Get the IP for the Kloudfuse endpoint.

    If the Kloudfuse stack installs with a DNS or VPC endpoint, use that address instead of the IP address.

    		 
    kubectl get svc -n kfuse | grep kfuse-ingress-nginx-controller-internal
kfuse-ingress-nginx-controller-internal   LoadBalancer   10.53.250.80    10.53.232.3   80:32716/TCP,443:30767/TCP   125m

  2. Create a file otel-values.yaml that contains the following code.

    Use the IP address from the previous step. Note that tls.insecure is true, which is default. Replace the endpoint, and ensure that you use https or http correctly, depending on Kloudfuse stack TLS protocol settings. See Configure HTTPS and TLS on Kloudfuse.

    Add any tolerations and affinity as required by your deployment.

  1. Add otel repo, and update it.

    helm repo add open-telemetry https://open-telemetry.github.io/opentelemetry-helm-charts
helm repo update

  2. Install the otel collector.

    helm install my-opentelemetry-collector open-telemetry/opentelemetry-collector -f otel-values.yaml
