[rrd-users] Re: Spikes (1.0.8)

[Tobias Oetiker]

Yesterday you sent me mail regarding RE: [rrd-users] Re: Spikes (1.0.8):

*> No, we are not mixing bits and bytes... The spikes occur
*> when the routers are reloaded or just sometimes randomly.
*> I can mail you dumps of the rrds if that helps. The target
*> machine is a FreeBSD 3.3 Intel unix server.

when you reset the router, then its internal counters get reset. If you have
not set proper min and max values in the DS definitions it can be that RRD
tool finds very large values ... If you think there is a bug in rrdtool it
would help a lot if you could produce an example set of data which
reproduces it ... 

cheers
