The Diagnostics tab on the appliance Status > Alerts and Diagnostics page provides the capability to run a series of system tests to determine the current state of the cloud service. As a best practice, it is recommended that you run these tests when you first deploy an appliance, and if you encounter any connectivity issues.
Click Run Diagnostics to start the tests. The Results column displays test status (In progress) and results (Passed, Failed, or Could not complete). For tests that do not complete or fail, the Details column displays more information, including suggestions for resolving the issue that caused the failure.
