A first overal setting for the offloads is the offload interval, which is by default 5 minutes.
In the 'Trend data' section it's also possible to set the offload interval for real time trending, which is by default 1 minute.
The offload for average trending is set to All timeframe records (5 minutes, 60 minutes).
How often will the realtime and average trending be pushed to central DB with these settings?
Especially for realtime trending it's a bit confusing.
Jeroen,
For real-time trend data this will be the specific value for the data offload in this case 1 minute to write the data to the files.
For average trending and the other settings checked this will be every 5 minutes.
