MRTG help?

Hey guys,

I have MRTG setup on the DA box... however, the traffic analysis graphs are mostly useless, because at 12am, 2am, and 4am, the traffic has big spike that throw the graph out of proportion.

Anyone have any ideas as to how to trim out the spikes?

I don't think you can change existing data, however you might be able to modify the default configuration so that it's less sensitive.
