Today you sent me mail regarding Re: [rrd-users] Spikes:

*> > it would be great if I could get some code demonstrating this behaviour ...
*> > it would make debugging so much simpler ... 
*> 
*> 	I don't know if this is related but I've also been seeing some
*> strange spikes in Octet readings I've been getting from one of my Cisco
*> Catalyst 8510 ATM switches. I'm still at the initial stages of debugging this
*> problem but this is what I have found so far.
*> 	Values as seen by my Perl script doing the collection before
*> passing them off to RRD:
*>                   'atm_out' => 3438905,
*>                   'atm_out' => 3457190,
*>                   'atm_out' => 1484,
*>                   'atm_out' => 19875,
*> 
*> 	Another sample:
*>                   'atm_out' => 3421998,
*>                   'atm_out' => 3452632,
*>                   'atm_out' => 26394,
*>                   'atm_out' => 58936,
*> 
*> 	Maybe, I'm missing something, but that sure looks like an odd wrap
*> point to me.	

maybe there are routers which do not wrap at 2^32-1 or 2^64-1 ... hmmm

grr

cheers
