[mrtg] How the interval value works...

Sorry about the cross-post, but I don't know which list this is more
appropriate for...

Another question for the MRTG / RRD 'leet out there: Can $interval in MRTG
be fractional?  I want 5-minute averages because that's what our upstream
uses to bill us, but an OC-3 can over-run a 2^32 counter twice in a 300
second poll!

After looking at the code, it looks like it just takes the $interval and
multiplies it by 60.  I was thinking of keeping the interval at 5 minutes,
but changing the multiplier to 30.  Of course, then in my cgi I'd have to
add every other poll to get a 5-minute average...  And looking more into it,
it would make just as much sense to change the interval to 2.5 - as long as
it's not looking for an integer.

Any suggestions / comments on this?
