Once a health check configuration is added to a site and you deploy DNS resolver service from that site, the health check configuration validates the health of the endpoint and reports the results in the health check results page. From the details panel of the health check, you can verify information about the health check and determine why certain endpoints are unhealthy.
In the top navigation bar, click

From the Health check results page, select the name of the endpoint to load additional information.
