In the following example from the NSX Advanced Load Balancer Controller web interface, the VS-Down event is shown associated with a new alert action named my-SNMP-alert-action. However, you can modify the default alert action System-Alert-Level-High. You can leave the system default alert action unchanged, and instead create a new custom alert action.
