You have one fixed amount of time (the duration of each log)
and the number of <whatever> per this fixed time.
To me it seems that you want to collect your data using GAUGE.
If you get 172800 messages each day, this is -->on average<-- 2 msg
per second. Just divide this number (172800) by the number of seconds
If you count the number of messages multiple times per day and thus
get a real wrap then yes, use either the NaN approach or the ABSOLUTE
Both ways would involve programming a front-end for RRDtool. When
you ask for automation you are asking for a front-end.
