That is like asking how long one should make a length of string. It really depends on what *you* want to be able to do with the data. In my presumably uncommon case I want three days of 1 second averages and then keep some number of weeks and months of 10 second and 1 minute (from memory, the other two RRAs aren't as important to me so I don't have it mesmerized at my fingertips as it were). rick jones > Thanks, > rrdtool create foo.rrd -s 15 DS:ds0:COUNTER:30:0:4294967295 \ > RRA:AVERAGE:0.5:4:240:? \ > RRA:AVERAGE:0.5:20:? \ > RRA:AVERAGE:0.5:60:? \ > RRA:AVERAGE:0.5:240:? \ > RRA:MAX:0.5:240:? \ > RRA:AVERAGE:0.5:5760:? \ > RRA:MAX:0.5:5760:? > _______________________________________________ > rrd-users mailing list > rrd-users@lists.oetiker.ch > https://lists.oetiker.ch/cgi-bin/listinfo/rrd-users _______________________________________________ rrd-users mailing list rrd-users@lists.oetiker.ch https://lists.oetiker.ch/cgi-bin/listinfo/rrd-users
