Parameters with CTL2 Expressions (Dynamic Parameters)
A CTL2 expression can be used in parameters, but it has to return a string
data type.
//#CTL2
function string getValue() {
return date2str(today(), "YYYY-MM-dd HH:mm:ss");
}
To assign CTL2 expression to a graph parameter, use the Edit Parameter CTL2 Value dialog.
You can access dynamic parameter’s value using getParamValue()
or ${PARAMETER_NAME}
. However, it is evaluated only once during the graphs initialization phase, since values are cached and constant throughout graph execution.
