FUNCTION
DescriptionFunction-specific parametersComments
between (value,min,max)
Check if a value belongs to the given range.value - value to check
min - minimum value
max - maximum value		Supported value types: integer, float

Returns:
1 - in range
0 - otherwise

Example:
=> between(last(/host/key),1,10)=1 - trigger if the value is between 1 and 10.
in (value,value1,value2,…valueN)
Check if a value is equal to at least one of the listed values.value - value to check
value1,value2,…valueN - listed values (string values must be double-quoted)		Supported value types: all

Returns:
1 - if equal
0 - otherwise

The value is compared to the listed values as numbers, if all of these values can be converted to numeric; otherwise compared as strings.

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.

Function details

Some general notes on function parameters:

  • Function parameters are separated by a comma
  • Expressions are accepted as parameters
between(value,min,max)

Check if the value belongs to the given range.
Supported value types: Integer, Float.
Returns: 1 - in range; 0 - otherwise.

Parameter:

  • value - the value to check;

  • min - the minimum value;

  • max - the maximum value.

Example:

  1. between(last(/host/key),1,10)=1 #trigger if the value is between 1 and 10
in(value,value1,value2,…valueN)

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:

  • value - the value to check;

  • valueX - listed values (string values must be double-quoted).

The value is compared to the listed values as numbers, if all of these values can be converted to numeric; otherwise compared as strings.

Example:

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