Data sources

I would expect that data sources with Poller Interval of 30 seconds are interrogated once every 30 seconds. Instead i'm seeing following log info:

Where you can see that datasource is called for update every 15 seconds. It seems that poller use global poller setting instead of respecting value setted in data source. Is it a bug or I'm missing something?

Thanks.

IMHO, current implementation is bad. So it may very well happen, that you've found a bug. Please file a bug report along with all of your findings
