Hey, as long I'm wasting bandwidth... :) It just occurred to me that my calculations prior on the number of KB per row(s) was wrong.
The calculation I used was 8.5MB / (4300 + 4300 + 2400) = MB / RRD row But after looking at the details of the RRD file, it appears I'm wrong, and the calc should look something like this: 8.5MB / (4300 + (4300*3) + (2400 * 3)) = MB / RRD row So, provided my new calculations are right, the general rough estimate for number of rows per MB is really something different. Also, I'm using 40 pings, rather than 20, so I have twice as many values as the default. So, it's probably really something like this 8.5MB / ((4300 + (4300*3) + (2400 * 3)*# of pings)) = MB / RRD row So, really, my calculations are pretty much bollocks. I'm sure there's a better formula - but it's probably just a whole heap easier just to create the dang thing and see how big it is. :) Which reminds me of that Calvin and Hobbes strip... http://www.s-anand.net/blog/calvin-and-hobbes-dad-explains-science/ "How do they know the load limit on bridges Dad?” “They drive bigger and bigger trucks over the bridge until it breaks. Then they weigh the last truck and rebuild the bridge.” “Oh. I should’ve guessed. -Greg _______________________________________________ smokeping-users mailing list [email protected] https://lists.oetiker.ch/cgi-bin/listinfo/smokeping-users
