[rrd-users] Re: rrdtool graph more average :)

[Warnes, Jason SktnHR]

Whew, I thought my email may have been a bit confusing.  I was getting
confused writing it.  :)  But it looks like you nailed it on the head.  As
you mentioned, an un avoidable side effect is the database size explodes,
but disk is cheap right?  :)

hmm,

In deed this might be the simplest solution in doing this now why didnt i 
think of this in the first place :)

new - old / 6 = value (negative or positive)
where value is what is needed to add every 10mins if real interwal is 
60minutes
that should work right then making the heartbeat 10mins instead of 60mins
higher datarate whould make it look better but then again it whould 
increase database size alot!
