A method for cloud service includes receiving, by processing circuitry that operates for a cloud service, a request including a first reporting descriptor object including (i) a first variables descriptor object associated with variables, (ii) a first events descriptor object associated with events, and (iii) a reporting interval. The method also includes generating, by the processing circuitry, at a time within the reporting interval, a message including a second reporting descriptor object with (i) a second variables descriptor object having updated values for the variables and (ii) a second events descriptor object associated with a subset of the events. The method also includes sending, by the processing circuitry, the message to a recipient.
