    Dapr 公开了一个 Prometheus 指标终结点，您可以扫描该终结点，以更深入地了解 Dapr 的行为方式，针对特定条件设置警报。

    默认指标端口为 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.
