Objet: Re: [hobbit] strange rrd data
It might be the "signed/unsigned" think that happens when counters roll over. In signed integers there is a "sign bit" that tells whether the value is positive or negative, and it can cause strange things to happen if one element treats a value as signed and another element treats it as unsigned. Just guessing, but a common source of error...
