Event Generation

Most hardware devices generate various events. These events usually reflect changes in device status or operating conditions. The Agent application maybe used to poll events from external hardware as well as generate them internally. These events are represented as context events in context provided by Agent.

Some Agents require reliable event delivery. Such Agents should declare a confirmEvent() function that will be called by the server each time it has received and successfully processed an non-system event from an Agent.

Some Agents can react to server-side event acknowledgements added by system operators. Such Agents should declare a acknowledgeEvent() function that will be called by the server each time an agent-declared event instance was acknowledged.

Sometimes is may be necessary to "push" new value of some changed Agent variable to the Iotellect Server and update settings cache without waiting for a regular synchronization cycle. If such case, Agent should generate and Updated event for the changed variable. Updated event contains name and new value of the variable. Iotellect Server will put new value to the server cache upon receiving Updated event if synchronization options for this variable don't block device-to-server synchronization.
