I've notice the when I graph mrtg rrd data older than a few months, the step size is always 24 hours. For example, if I graph mrtg data (gathered at 5 minute intervals) from 6 months ago, it's clearly graphed in 24-hour step sizes:
rrdtool graph - \ --start='7/11/2006' \ --end='7/13/2006' \ --imgformat=PNG \ --width=1024 \ --base=1000 \ --height=256 \ --interlaced \ DEF:a=/var/www/mrtg/rtr-wan-mci//my_rtr_3.rrd:ds0:MAX:step=300 \ DEF:b=/var/www/mrtg/rtr-wan-mci//my_rtr_3.rrd:ds1:MAX:step=300 \ LINE1:a#008000:'Serial0/3/0 in' \ LINE1:b#0000FF:'Serial0/3/0 out' Produces a graph that only shows changes at 7pm each day, even though I forced the step in the DEF to 300 seconds. I also tried the --step=300 leaving out the 'MAX:step=300' from the DEFs, with the same result. I also tried with start and end times anywhere from an hour apart to a day apart, and still there I couldn't get 300 second steps. Is that just how RRD works, or is there a way to get the 5-minute granularity from older time periods? -- Unsubscribe mailto:[EMAIL PROTECTED] Help mailto:[EMAIL PROTECTED] Archive http://lists.ee.ethz.ch/rrd-users WebAdmin http://lists.ee.ethz.ch/lsg2.cgi
