Hi all, I tried to change the samples collection time from 5 minutes to 15 minutes but failed.
Here are the steps that I have done: 1. Create a rrd with steps = 900 by rrdtool create router.rrd --step 900 \ DS:ifInOctets:COUNTER:600:U:U \ DS:ifOutOctets:COUNTER:600:U:U \ RRA:AVERAGE:0.5:1:600 \ RRA:AVERAGE:0.5:6:700 \ RRA:AVERAGE:0.5:24:775 \ RRA:AVERAGE:0.5:288:797 2. Change crontab so that the data would be collected every 15 minutes. However, I found that no data could be input in router.rrd. (I use the command "rrdtool fetch router.rrd AVERAGE" to view data in router.rrd. I c that all values are "nan".) Anybody knows what happen? Thanks a lot!!
