I don't understand why you think you can retrieve 5-minute samples... You write it yourself: the part of the RRD that lasts 12.5 days has 30-minute samples ?!? You are right in saying that there is only 50 hours worth of 5-minute samples. If you go back further than 50 hours, the next RRA is choosen and thus you can't have 5-minute samples. cheers, -- __________________________________________________________________ / [EMAIL PROTECTED] [EMAIL PROTECTED] \ | work private | | My employer is capable of speaking therefore I speak only for myself | +----------------------------------------------------------------------+ | Technical questions sent directly to me will be nuked.
