Is it true that every retrieveStatisticRequest can only get a statistics for one single object?
Does that mean if I want to get total not_ready_time for 100 agents from a agent group, then I need to send 100 retrieveStatisticRequest ?
I am not sure which version you plan to use. But at least 7.5 version gave you possibility to subscribe bunch of stats (subscribeStatistic), and then use retrieveSubscribedStatistics to get list of all what you earlier subscribed..
