Hi all.
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.
