Above the defined threshholds

Default threshold values

High:3
Medium:1
Low:0

Note: Alert thresholds are directly linked to the integer values of the Database state metric on which the alert is based. By default, any value over 0 (ONLINE) requires attention. Values 1 (RESTORING) and 2 (RECOVERING) are common states, but do mean the database is unusable while the database. Values of 3 (RECOVERY_PENDING) and higher (4 = SUSPECT, 5 = EMERGENCY, 6 = OFFLINE, 7 = Database Does Not Exist on Server) indicate that the database will not be available without user intervention. These thresholds are intended as guideline values. If they seem too high or too low, replace them with values more suited to your own server performance.
