I have some problems with interface graphs. Basicially they are looking ok, but
sometimes there are gaps for the outbound traffic. The cacti log looks good, the
values are received via snmp. But they are not in the rrd file. The maximum
value for this data source is 1.0000000000e+07 (64bit counters). The interface
in this example is the uplink for a 125Mbit/s line and there is a gap for the outbound traffic between 3 and 5 o'clock.
I can't see a reason why there are gaps in the rrd file and in the graphs
too.
