Hi.

I don't know why --step is omited, but if no value for --step is givven
it defaults to 300 seconds (see man rrdcreate). Also you should adjust 
the 600sec. heartbeat interval and increase the number of rows in the
RRA from 240.

But if you want to know _why_ check_traffic uses 5min interval instead
1minute ... well you have to ask the author.

HTH,

Andreas.
