DEFINING THRESHOLD FORMULAS

Threshold Formula

The threshold formula uses Backus-Naur Form (BNF) as follows:

Threshold::=	SimpleExpression
	ComplexExpression
	<NULL>	-- Nothing
SimpleExpression::=Variable rel_op Value
Variable::=	"R"	-- Value of data
	"H"	-- Changes in data per hour
	"M"	-- Changes in data per minute
	"S"	-- Changes in data per second
rel_op::=	">"	-- Greater than
	"<"	-- Less than
	">="	-- Greater than or Equal to
	"<="	-- Less than or Equal to
	"=="	-- Equal
	"!="	-- Unequal

Value::=<INTEGER VALUE> -- Number represented in decimal digits, within the range of a 4-byte unsigned integer.

ComplexExpression::=

"(" SimpleExpression ")"

"(" ComplexExpression ")"

ComplexExpression logic_op ComplexExpression

logic_op::="AND""OR"
