It doesn't help if you only have RRAs with 1 PDP per CDP, if you graph 1600 minutes then you will *have to* combine four PDPs into one pixel. Yes, this means averaging. Yes, this means you cannot have exact numbers as fetched from the source. This is how RRDtool works. This is how rates work. Everything is computed into an x per second value. You may be able to produce something that looks like what you want. This would involve LAST as a consolidation function. However I think this will show up as 35 if a range of "23 56 10 35" is consolidated. (I'm not sure. Can anybody who knows for sure tell please?) The closest you can get is to enter the values at suitable times. This means cheating: in stead of the real time you tell RRDtool to store it at time-(time modulo 60). Example: if now == 997745684 then you store the sample at 997745684 - 44 = 997745640. The numbers will be whole numbers in the RRA that has 1 PDP per CDP. When averaged into the RRA with 4 PDPs per CPD, you will end up with numbers that are x.25, x.50 or x.75, perhaps you want to round those using RPN instructions in a CDEF. This is not what you should want. You could also think of a perminute display, a perhour display, a perday display etcetera. All numbers end up in the database as rates (x per second) and can thus be multiplied by a number of seconds. Alternative to this suggestion: if your database contains GAUGE entries of number of users per minute, you can multiply by 60 to get the number of users per hour. 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.
