Unfortunately, you've hit a limitation in the 32-bit counter. Unless there's a 64-bit one you can start polling, your best bet is to convert over to a 1-minute polling interval. At that rate, you shouldn't see a double-wrap until about the low-500Mbps mark.

I'm monitoring a STM1, and I'm having problems when it gets over 100 Mbps. I'm getting que in traffic via snmp. The problem is when the traffic is really high and the router's counter gets wrap. The counter is 32bits length. Some examples of the counter's value are: 1649124260 , 1985404175, 2410413980 , 3137526950, 3728976455, 4188225691, ... counter wrap .. , 180039546, 619861589. My rrd file was created in this way: rrdtool create /usr/lib/cgi-bin/graphs/rrds/test.rrd \ DS:input:COUNTER:600:0:4294967295 \ DS:output:COUNTER:600:0:4294967295 \ RRA:AVERAGE:0.5:1:600 \ RRA:AVERAGE:0.5:6:700 \ RRA:AVERAGE:0.5:24:775 \ RRA:AVERAGE:0.5:288:797 \ RRA:MAX:0.5:1:600 \ RRA:MAX:0.5:6:700 \ RRA:MAX:0.5:24:775 \ RRA:MAX:0.5:288:797 With these values, I'm getting a wrong graph, I mean the high traffic is not drawn properly, is drawn as a low traffic instead. What can I do to get the right graph ? Thanks in advance. -- _________________________________ Ing. Pablo A.
