AWS::IoTEvents::AlarmModel AssetPropertyValue

Examples

• For literal values, the expressions must contain single quotes. For example, the value for the quality parameter can be 'GOOD'.

• For references, you must specify either variables or input values. For example, the value for the quality parameter can be $input.TemperatureInput.sensorData.quality.
