Sorry for to invade the conversation, but I am interested in this

I am still using rrdtool 1.0.49
Thanks

I assume the objective of this is to stop the single nightly traffic spikes?

Apart from the fact that stopping MRTG wont stop the network counters, there
are several better ways to do this.

1) If you are using routers2 as your frontend, then just click on the
'rescale' button and it will trim off the spike to show you the detail.
2) If you are using RRD as a backend, you could run killspike.pl on the RRD
file nightly to erase the data.
3) Set MaxBytes on the target so that it doesnt allow high data.
4) Generate your graphs with an enforced upper-limit to the Y axis.

We use (1) of course :)

Steve
