Represents how critical an alarm is. A severity determines how Foglight for SQL Server behaves when the values for a metric fall within a user-defined range of values. A severity specifies whether the information returned in the metric represents normal or abnormal behavior for the system under diagnosis. For example, unusually high values might mean that a metric has crossed a threshold into a high severity state. This, in turn, could change the color of a component on the home page; for example, from orange to red when moving from a critical to a fatal state.
The severity determines what action Foglight for SQL Server takes when a metric value falls into the range defined by a threshold.
