Returns: 1 - in range; 0 - otherwise.

Parameter:

• value - the value to check;
  
• min - the minimum value;
  
• max - the maximum value.

Example:

Check if the value is equal to at least one of the listed values.
Supported value types: Integer, Float, Character, Text, Log.
Returns: 1 - if equal; 0 - otherwise.

Parameter:

Example:

in(last(/host/key),5,10)=1 #trigger if the last value is equal to 5 or 10
       in("text",last(/host/key),last(/host/key,#2))=1 #trigger if "text" is equal to either of the last 2 values
