See Configure/Alarm Settings page, click Alarm Events, to see all alarm types that are supported.
Only one alarm email is sent for each event. If the same event happens again, no alarm will be
sent until you clear the alarm on the Monitor/All Alarms page.
AP interference levels are not monitored until/unless they cause the AP to reboot (lost contact).https://support.ruckuswireless.com/documents/1609-zonedirector-10-0-ga-zd-user-guide
If you can give your business case for Interernce alert emails to your local Ruckus SE, he can
