Very interesting. Not very easy to guess though :-), thanks. Can we have any interval? I wonder what's the utility of having several RRA lines. My creation was like RRA:AVERAGE:0.5:1:17280 \ RRA:AVERAGE:0.5:12:2880 \ RRA:AVERAGE:0.5:720:720 \ RRA:AVERAGE:0.5:17280:365 \ RRA:MAX:0.5:1:17280 \ RRA:MAX:0.5:6:2880 \ RRA:MAX:0.5:24:720 \ RRA:MAX:0.5:288:365 If we can get any interval from the resolution, as the manual says it'll try to, only one RRA for average would be necessary. I've tried several values, substituted in END=..., but only those corresponding to an interval of one of the RRA lines worked. Now, the manual says rrdgraph will adjust the resolution to the size of the gif. But if one cannot specify any resolution, it means one cannot have an arbitrary size for the gif, right? -- Unsubscribe mailto:[EMAIL PROTECTED] Help mailto:[EMAIL PROTECTED] Archive http://www.ee.ethz.ch/~slist/rrd-users WebAdmin http://www.ee.ethz.ch/~slist/lsg2.cgi
