Hello, I'm using rrdtool together with mrtg and wan't to read the data with a php script (similar to mrts). Now I facing some problems according to the different RRA I used.
When I fill up the rra with data and compare the data for the "last" day with the following command (<resolution> : 300, 1800, 7200, 86400) I got different results (for the same range of time): rrdtool fetch data.rrd AVERAGE -r <resolution> -s 1160438400 -e 1160524800 Resolution | Result 86400 | 1,7567 7200 | 1,7611 1800 | 1,7201 300 | 1,7201 I though it could not differ, because the small resolution (300) database feed the larger one (1800) and so on ? Where is my fault?
