>From Tobi's email, it seems that MRTG can now accept decimal intervals (I wonder when this was added? I'm behind the times).  However it still holds that the routers2 frontend will not show graphs for smaller periods than 6 hours, IE, 1min-per-pixel, so you'll need to have some other way of displaying them.  I think 14all and default mrtg-rrd will also only show Daily graphs (IE, 5min interval) and not smaller (but I may be behind the times on these, too?)
