Configure Dapr to send distributed tracing data
NoteIt is recommended to run Dapr with tracing enabled for any production scenario. You can configure Dapr to send tracing and telemetry data to many observability tools based on your environment, whether it is running in the cloud or on-premises.
tracing section under the
Configuration spec contains the following properties:
spec: tracing: samplingRate: "1" otel: endpointAddress: "https://..." zipkin: endpointAddress: "https://..."
The following table lists the properties for tracing:
||string||Set sampling rate for tracing to be enabled or disabled.|
||bool||True write more verbose information to the traces|
||string||Set the Open Telemetry (OTEL) server address.|
||bool||Is the connection to the endpoint address encrypted.|
||string||Set the Zipkin server address. If this is used, you do not need to specify the
To enable tracing, use a configuration file (in self hosted mode) or a Kubernetes configuration object (in Kubernetes mode). For example, the following configuration object changes the sample rate to 1 (every span is sampled), and sends trace using OTEL protocol to the OTEL server at localhost:4317
apiVersion: dapr.io/v1alpha1 kind: Configuration metadata: name: tracing spec: tracing: samplingRate: "1" otel: endpointAddress: "localhost:4317" isSecure: false protocol: grpc
Dapr uses probabilistic sampling. The sample rate defines the probability a tracing span will be sampled and can have a value between 0 and 1 (inclusive). The default sample rate is 0.0001 (i.e. 1 in 10,000 spans is sampled).
samplingRate to 0 disables tracing altogether.
The OpenTelemetry (otel) endpoint can also be configured via an environment variables. The presence of the OTEL_EXPORTER_OTLP_ENDPOINT environment variable turns on tracing for the sidecar.
||Sets the Open Telemetry (OTEL) server address, turns on tracing|
||Sets the connection to the endpoint as unencrypted (true/false)|
||Transport protocol (
