Yesterday you sent me mail regarding [rrd-users] Spurious averages being...:
*> I'm having a lot of trouble when the counters on my routers/machines
*> roll around and am getting averages of up to 100MBits.
*> IE the counter gets to 4 billion odd, wraps, and the graphs show
*> nothing but a HUGE spike (the average speed is usually about 100kbit to
*> 1mbit on any interface.
*> Also, if a machine is turned off and then on, the counter is reset, and
*> the same problem occurs.
*> What can I do to fix this?
a) make sure you set min and max values for your rrds either when creating
or with tune ...
b) one the limits are set you can do a dump restore cycle and have restore
check for invalid entries in the rrds ..
normal counter wraps btw should be recognized by rrdtool and handled
