1 At nms=1000, the manager does the baseline poll to get everything since the last agent restart (Timefilter =0)
2 At nms=2500 (15 second later), the manager get an update on all changes since the last report (agent time=600)
GetRequest (sysUpTime.0, fooCounts.600.1, fooCount.600.2)
The agent received the request at a local time of 2100 ; a counter 1 was incremented at time 900 counter 2 was incremented at 1100 and 1400
3 At nms=4000, the manager get an update on all changes since the last report (agent time=2100)
GetRequest (sysUpTime.0, fooCounts.2100.1, fooCount.2100.2)
A counter 1 was incremented at time 2300 counter 2 has not changed since 2100 , so no value returned
4 At nms=5500, the manager get an update on all changes since the last report (agent time=3600)
GetRequest (sysUpTime.0, fooCounts.3600.1, fooCount.3600.2)
Neither counter has been updated since time 3600 , so no value returned
