Configure Observability

Configuring platform observability

Setup metrics

Custom metrics are collected by Prometheus, to enable this, install Prometheus into your Kubernetes cluster. By default, the operator will configure Prometheus to scrape metrics from the OpenTelemetry collector. To publish custom metrics, use the Prometheus client library, and push them to http://otel-collector:4317

Install Prometheus

kubectl create namespace dapr-monitoring
helm repo add prometheus-community https://prometheus-community.github.io/helm-charts
helm repo update
helm install dapr-prom prometheus-community/prometheus -n dapr-monitoring

To explore the metrics, forward a port to the Prometheus server to your local machine.

kubectl port-forward services/dapr-prom-prometheus-server 82:80 -n dapr-monitoring

In your browser, go to http://localhost:82 and you will see the Prometheus UI.

Setup tracing

Traces are sent by the Dapr sidecar to Zipkin. To enable this, install Zipkin in your Kubernetes cluster.

Install Zipkin

kubectl create deployment zipkin --image openzipkin/zipkin
kubectl expose deployment zipkin --type ClusterIP --port 9411

To explore the traces, forward a port to the Zipkin server to your local machine.

kubectl port-forward svc/zipkin 9411:9411

In your browser, go to http://localhost:9411 and you will see the Zipkin UI.
