Data logging every 15min, No Data, Bad Data
I try to log a signal every 15min. The goal is to summarize the value for the last 15 min.
I am using the following log configuration:
1. Log: every second for 30min (Direct Log)
2. Log: Total every 15min (Hierarchical)
The log seems to work properly, but some data are bad, see the next print screen...
If the data is bad, the total value of the last 15min is also to low.
I use this log for statistical evaluation with DataDirect. If I have several bad data in my statistic, this statistic will not be plausible.

Is the one second log missing data or does it have one bad sample ?
You have the "Bad Data Quality Limit" set to 0%, so even one bad sample will cause the entire 15min totalised value to be bad. Try setting this to some small value ( say 1 % ) so that it can handle some bad data but still not loose accuracy.
