Yes, but you'll need to regenerate your databases (logs under "native" MRTG, .rrd under RRDTool) because the current resolution of 5 minutes will still be there. You'll need to restart MRTG once you've installed RRDTool and set the interval to 1. > > I believe that you're thinking of MRTG as being more than it is. MRTG > > is a collector.

Neither will 1 minute intervals. You need to set up snmp on your router to send a trap when your line has reached maximum capacity. That is the ONLY was you'll get this. Not even a 1 second polling granularity will give you this information. And in going down to 1 second, you've introduced a TON of potential errors.
