    If you look into the lo stream of voltha, you can see an entry every 3 seconds indicating that voltha received the health check request and responded (you need -v (verbose mode) enabled to see these).
   
-   One way to see the health checks are passing is to point your browser to the user interface of consul: [http://10.100.198.220:8500/ui](http://10.100.198.220:8500/ui). Click on the voltha-rest entry and you shall see its passing two health tests, the one with the name volta-rest is our healthcheck.

 6. Consul exposes the service records also as a DNS server. This is how it can be used:
 
    To check the IP address(es) for voltha's REST interface, you can use:
    
    ```
-   dig @localhost -p 8600 voltha-rest.service.consul
+   dig @localhost -p 8600 voltha-health.service.consul
    ```
    
    Which shall print, among other things an A record:
    
    ```
-   voltha-rest.service.consul. 0  	IN     	A      	10.0.2.15
+   voltha-health.service.consul. 0  	IN     	A      	10.0.2.15
    ```
    
    Or if you want the IP adress only:
    
    ```
-   dig @localhost -p 8600 +short voltha-rest.service.consul
+   dig @localhost -p 8600 +short voltha-health.service.consul
    ```
