hi, I would like to ask is my calculations correct.. what I want is to display as much as better graphics.. so here goes.. with the deafult rrdgraph-image-with I have 400px usable area for plotting the data. Now with this in mind I have to calculate the correct "steps" in RRA. /cdp-interval is 5 min = 300sec, time is interval for which i need graphics/
(time/cdp-interval) * steps = image-useble-width steps = (time/cdp-interval)/image-useble-witdh steps = time/(cdp-interval * image-useble-witdh) steps = time/(300 * 400) steps = time/120 000 Now if I want to calculate this for day(86400 sec), week (604800), month (18748800), year (31536000) steps = 86400/120 000 = 0.72 => 1 steps = 604800/120 000 = 5.04 => 5 steps = 18748800/120 000 = 156.24 => 156 steps = 31536000/120 000 = 262.8 => 263 so my rrdcreate should be : "RRA:AVERAGE:0.5:1:400", #day, it can be 288 instead 400 "RRA:AVERAGE:0.5:5:400", #week "RRA:AVERAGE:0.5:156:400", #month "RRA:AVERAGE:0.5:263:400", #year Is my calculations correct... !!!! If they are correct put them in some how-to :") tia -- 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
