Dapr exposes a Prometheus metrics endpoint that you can scrape to gain a greater understanding of how Dapr is behaving and to setup alerts for specific conditions.
The metrics endpoint is enabled by default, you can disable it by passing the command line argument
--enable-metrics=false to Dapr system processes.
The default metrics port is
9090. This can be overridden by passing the command line argument
--metrics-port to Daprd. Additionally, the metrics exporter can be disabled for a specific application by setting the
dapr.io/enable-metrics: "false" annotation to your application deployment. With the metrics exporter disabled,
daprd will not open the metrics listening port.

To disable the metrics collection in the Dapr side cars running in a specific namespace, you can use the
metric spec configuration and set
enabled: false to disable the metrics in the Dapr runtime.

Each Dapr system process emits Go runtime/process metrics by default and have their own metrics:
