The ability to send email notifications for Faults is a great feature, but I only realized today that it must be enabled for each fault individually. The text under the setting implies that you simply need to turn this switch and will receive notifications:
"Automatically sends email when notification enabled faults are detected"
Just enabling the "Email Notifications" on the "Faults" tab under "Insights" does not actually do anything. It appears that you have to click the triple dots to the right of each fault (Enable Email Notifications) and configure it to send a notification to a specific recipient.
Given the above, I think the following would be helpful additions:
Add more columns (by selecting the gear) to show:
Which faults are setup for email notifications (this should be a default).
Which Email addresses configured as recipients for those faults.
The ability to select multiple faults at one time and then enable email notifications as well as configure the recipients.
On the main "Fault Settings" tab, add a tool tip to indicate that you need to enable each fault separately, as well as configure the recipient settings.
