  The EaseProbe would listen on the `0.0.0.0:8181` port by default. And you can access the Live SLA report by the following URL:
 
- - HTML: `http:https://localhost:8181/`
+ - HTML: `http:https://localhost:8181/` or `http:https://localhost:8181/?refersh=30s`
  - JSON: `http:https://localhost:8181/api/v1/sla`
 
  Refer to the [Global Setting Configuration](#38-global-setting-configuration) to see how to configure the access log.
