Select the Category, or pick "All events" for everything.
Either pick All Events, or a Subset of Events. If the subset is selected,
customize the checkbox list to match the desired alerts events.
Use the drop down menu in "Alert actions" to select which alert type.
Enter details for the Alert action. The "TEST" button can be clicked to create
a test alert and execute this alert action (useful for checking if email or SNMP
is configured correctly).
The add icon next to "Alert actions" can be clicked to add multiple alerts
actions.
