You have "--step 60" and update every 10 seconds. Your finest RRA will
> still contain a composed number built from 6 updates.
Update every 10 seconds is a little bit "aggressive" but it is not really
needed, you're right. The reason is that when I run my tests, I only need
10s to have an update and check that everything works (graphs update is
also every 10s)
But do you confirm that I can update with a higher freq than de DB ? Let's
say update every 30 sec still have sense ?

Mmmm... the next points will show that... no :(

arglll... I'm totally wrong !

Thanks for the warning, but it is not a very big issue in my case (unless
for the 23h and 25h days which will show abnormal low or high consumption).
Let's use UTC time.
