(or better the next valid slot and sleep until that time has come [and than gather fresh data to fill in]) rrdfirst accepts an parameter named rraindex. do i have to look in a rrddump to gather a valid rraindex or is there a better way? that rraindex would serve my calculation perfectly well, wouldn't it? >You need to have updatetime = n * 300 yes. the last 20 lines of this mail i tried to question how to determine n. :) can you give me a hint, if i don't have the information of rrdcreate? thanx in advance. cheers thomas -- Unsubscribe mailto:[EMAIL PROTECTED] Help mailto:[EMAIL PROTECTED] Archive http://lists.ee.ethz.ch/rrd-users WebAdmin http://lists.ee.ethz.ch/lsg2.cgi
