Hi there... Ok, I have finally the hang of most of what I intended to do.
Logging my power usage ; then calculating power consumption as charged by the electricity company (in kWh). http://htpc.avenard.org/power/ For each graph; you can click on a part of the graph ; and it goes down to one resolution down (e.g weekly view gives you daily view etc...) For the power usage ; I want to show the data as follow: daily: midnight to midnight local time weekly: midnight of day -7 to midnight previous day local time monthly: midnight of day-30 to midnight previous day local time yearly: doesn't really matter. daily view is averaged per hour weekly view is averaged per day monthly view is averaged per day yearly view is averaged per month (30 days) I created the RRD with data being fed every minute and keeping consolidated data as follow: 100 days of 1 minute average 5 years of 5 minutes average 5 years of 30 minutes average 5 years of 1 hour average 5 years of 2 hours average 5 years of daily average Everything is nice and rosy but for the weekly and monthly view... The average isn't calculated from midnight to midnight local time ; even though I provide end and start data at those values. For the weekly view, the x-grid is 'HOUR:3:DAY:1:HOUR:24:86400:%a' As you can see on the weekly graph: http://htpc.avenard.org/power/?graph=2&view=week A plot doesn't start at midnight ; but around 11AM. I understand that this is UTC time ; I read http://www.vandenbogaerdt.nl/rrdtool/timezone.php and in particular this thread: http://groups.google.com/group/mailing.unix.rrd-users/browse_thread/thread/326e32b152c9f6a9 Is there any way to make the plotted bar goes from midnight to midnight local time, and calculate the average of the data of a day (local time)? If I set TZ to UTC ; then obviously the x axis matches the graph perfectly ; but that's not what I want to do... Thank you...
