All configured DCIs are checked for polling requirement every two seconds and if DCI needs to be polled, appropriate polling request is placed into internal data polling queue. First available data collector will pick up the request and gather information from the node according to DCI configuration. If a new value was received successfully, it's being stored in the database, and thresholds are checked. After threshold checking, data collector is ready for processing new request. Processing of a newly received parameter value is outlined on Figure 4 | All configured DCIs are checked for polling requirement every two seconds and if DCI needs to be polled, appropriate polling request is placed into internal data polling queue.
