I want to make rrd graphs similar to how MRTG works & I am logging various temperatures at 5 minute intervals. Are these the correct formulas to feed into "rrdtool create" so it has the correct data to make the graphs? I couldn't find "cookbook recipes" for this anywhere, although I'm sure it has been done many times before...

For Daily Graph, every 5 minute average for 24 hours:
RRA:AVERAGE:0.5:1:288

For Weekly Graph, every 30 minute average for 7 days:
RRA:AVERAGE:0.5:6:336

For Monthly Graph, every 2 hour average for 30 days:
RRA:AVERAGE:0.5:24:360

For Yearly Graph, every 1 day average for 365 days:
RRA:AVERAGE:0.5:288:365

Thanks,
Josh

For Daily Graph, every 5 minute average for 24 hours:
RRA:AVERAGE:0.5:1:288

ok theres 24 hours in a day
1440 minutes in a day
your are logging every 5 minutes
therefore you want to use 288 logs per day

same goes with the rest of them

For Weekly Graph, every 30 minute average for 7 days:
RRA:AVERAGE:0.5:6:336

7 days * 24 hours * 60 mins = 10080 mins
you log every 5 mins so 10080/5 = 2016 samples per week
you want to average every 6 samples so 2016/6 = 336


im still learning how to use rrdtool but reading through the online help on the website
http://people.ee.ethz.ch/~oetiker/webtools/rrdtool/

and going through the samples and tutorials at
http://martybugs.net/linux/rrdtool/traffic.cgi

i am getting better

good luck
