Configure metrics

Enable or disable Dapr metrics

By default, each Dapr system process emits Go runtime/process metrics and has their own Dapr metrics.

Prometheus endpoint

The Dapr sidecars exposes a Prometheus metrics endpoint that you can scrape to gain a greater understanding of how Dapr is behaving.

Configuring metrics using the CLI

The metrics application endpoint is enabled by default. You can disable it by passing the command line argument --enable-metrics=false.

The default metrics port is 9090. You can override this by passing the command line argument --metrics-port to Daprd.

Configuring metrics in Kubernetes

You can also enable/disable the metrics for a specific application by setting the dapr.io/enable-metrics: "false" annotation on your application deployment. With the metrics exporter disabled, daprd does not open the metrics listening port.

The following Kubernetes deployment example shows how metrics are explicitly enabled with the port specified as “9090”.

apiVersion: apps/v1
kind: Deployment
metadata:
  name: nodeapp
  labels:
    app: node
spec:
  replicas: 1
  selector:
    matchLabels:
      app: node
  template:
    metadata:
      labels:
        app: node
      annotations:
        dapr.io/enabled: "true"
        dapr.io/app-id: "nodeapp"
        dapr.io/app-port: "3000"
        dapr.io/enable-metrics: "true"
        dapr.io/metrics-port: "9090"
    spec:
      containers:
      - name: node
        image: dapriosamples/hello-k8s-node:latest
        ports:
        - containerPort: 3000
        imagePullPolicy: Always

Configuring metrics using application configuration

You can also enable metrics via application configuration. To disable the metrics collection in the Dapr sidecars running in a specific namespace:

  • Use the metrics spec configuration.
  • Set enabled: false to disable the metrics in the Dapr runtime.
apiVersion: dapr.io/v1alpha1
kind: Configuration
metadata:
  name: tracing
  namespace: default
spec:
  tracing:
    samplingRate: "1"
  metrics:
    enabled: false
