Our customer would like to calculate the data point value in 1 message.  
To check Octave user guide ([Using the REST API in an External System](https://docs.octave.dev/docs/using-the-rest-api-in-an-external-system#getting-events-from-octave)), we saw the following sample code in “Sending Events to Octave”.
