Required - A JSON representation of the Calculated expression object
  • regex_property_identifier - Required - String - The identifier of the event regex property to which this expression belongs.
  • enabled - Optional - Boolean - Flag that indicates whether this expression is enabled. It defaults to true if not provided.
  • first_operand - Required - Operand Object - An object describing the first operand in the expression.
  • second_operand - Required - Operand Object - An object describing the second operand in the expression.
  • operator - Optional -String - A string that represents one of the basic arithmetic operations in the expression. Defaults to "ADD".
  • payload - Optional - String - Test payload. This parameter is only used in the UI so that you can verify that your expression matches the expected payload.
  • log_source_type_id - Required - Integer - The expression is only applied to events for this log source type.
  • log_source_id - Optional - Integer - The expression is only applied to events for this log source (more specific than type alone).
  • qid - Optional - Integer - The expression is only applied to events associated with this QID record.
  • low_level_category_id - Optional - Integer - The expression is only applied to events with this low level category.

Response Description

The newly created Calculated expression that contains the following fields:
  • id - Integer - The sequence ID of the Calculated expression.
  • identifier - String - The unique ID of the Calculated expression. This value is in the form of a UUID.
  • regex_property_identifier - String - The identifier of the event regex property to which this expression belongs.
  • enabled - Boolean - Flag that indicates whether this expression is enabled.
  • first_operand - Operand Object - An operand object describing the first operand in the expression.
  • second_operand - Operand Object - An operand object describing the second operand in the expression.
  • operator - String - A string that represents one of the basic arithmetic operations in the expression.
  • creation_date - Long - The epoch timestamp in milliseconds of the time the expression was created.
  • modification_date - Long - The epoch timestamp in milliseconds of the time the expression was last modified.
  • payload - String - Test payload. This parameter is only used in the UI so that you can verify that your expression matches the expected payload.
  • log_source_type_id - Integer - The expression is only applied to events for this log source type.
  • log_source_id - Integer - The expression is only applied to events for this log source (more specific than type alone).
  • qid - Integer - The expression is only applied to events associated with this QID record.
  • low_level_category_id - Integer - The expression is only applied to events with this low level category.
  • username - String - The owner of the Calculated expression.
An operand object contains the following fields:
  • type - String - can be "STATIC" (for numeric operand) or "PROPERTY" (for operand that is a property).
  • numeric_value - Number - when property_type is "STATIC", this is the value of the operand; otherwise, it is suppressed.
  • property_name - String - when property_type is "PROPERTY", this is the name of the property that is being used as the operand; otherwise, it is suppressed.
