I had previously opened
[METRON-450](https://issues.apache.org/jira/browse/METRON-450) to help the user
with this kind of problem. With METRON-450, I could query the types of
profiles that I have and see that profile P has a duration of D. This would
help the user understand that they are using the wrong period duration, among
other things.
METRON-450 is not exactly what you're looking for, but I thought I would
mention it.
