Hi. The item trends record are kept in mysql database. It seems the trends records are written into the database every 1 hour. Now I need the trends datas of every half hour. Where can i customer this interval?
Anyone knows ? Thanks in advance!

The trending interval is not configurable. I don't know your requirements but perhaps you could you use data from history instead if it makes sense to you.

Thanks, Alexei. I see. I just want to do some statistiscs. The datas in Trends are somehow statistical. So if i could use the Trends datas other than the origin datas in history, I would search quite a lot fewer datas and save much more time. But i need the datas by every half an hour, for example, 9:00-11:30 am, so, I'm afraid i have to use the history datas. Thank you.
