Following on from Alex explanations has anybody else managed to successfully create daily/weekly consolidated data points based in non UTC/GMT timezones either as a chart or xport.

I thought I was beginning to understand this but from your two previous emails I have to ask one last questions (I hope).... "How do I get an average value for a week (step=604800) starting on a Monday." All this sort of leads back to my original question which I attempted to pose to the development mailgroup having found a reference to in one of the archives... "Is it still being considered for future versions to enable the origin of an rrd chart to be at a specified point in time in addition to the default of epoch." The reason behind the variety of chart resolutions is aimed at different people. Technicians what access to detailed intra-day data (5 minutes) as well as the longer term trends.

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. HTH Alex -- I ask you to respect any "Reply-To" and "Mail-Follow-Up" headers. If you reply to me off-list, you'd better tell me you're doing so. If you don't, and if I reply to the list, that's your problem, not mine. -- 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 ------------------------------------------------------------------------------ This message is intended only for the personal and confidential use of the designated recipient(s) named above.
