If you are trying to build images like the one attached in http://www.ee.ethz.ch/~slist/p/image_7089.png , you probably do not want to update each minute. IF you try to do so: Set heartbeat to a large number (larger than 86400) and update at midnight only. > RRDs::graph (-imgformat,PNG > --width,500, > --height, 300, > --step, 86400, step 86400 ... > --start, 1092628800, > --end, 1093233600, ... but: 1092628800 mod 86400 != 0 -> cannot work 1093233600 mod 86400 != 0 -> cannot work RRDtool will modify the start and end so that it _is_ n*86400. > --step 86400, another step. Get rid of them both. > 1092628800 = Monday 16 August 2004 00:00 EDT (I think!) > 1093233600 = Monday 23 August 2004 00:00 EDT (I think!) if EDT is four hours behind UTC then this is OK. perl -e 'use POSIX; print ctime(1093233600);' will show the wall clock time.
