Alert rule, event's level precedence order

We are setting up an alert rule and would only like to trigger the alert if the event’s level is greater than info. Looking through the documentation I cannot find anywhere were the precedence of these levels are stated. Since the rule greater than or equal to I need to know what is one level above info which I cannot reliably identify. The alert rules event level dropdown contains: fatal, error, warning, info, debug, and sample. Perhaps this is the order as they are in the dropdown? Would be nice to know for sure.

Thank you,
