Hi,
Please, how could I fix this ? My pollers aren´t in sync...
and I´m detecting chart gaps...
The sync time does not need to be spot on time synch'd between each poller, but you shouldnt get a DB sync of over 10 seconds without it affecting data quality, which this is moving towards and demonstrated by your statement of gaps appearing in your charts.
The following KB article will assist with determining the cause and resolution:
