Internals
Database connection problem
The dashboard icon for the Trending App will show a message when the database connection is not working properly:
In this case the Trending App cannot be started.
Recording data
A trending is based on a Server Item.
If the Item Quality property of the Server Item is "UNCERTAIN", no values will be recorded for the trending. The recording of values starts as soon as the Item Quality property is "GOOD".
