I'm tying to create and RRD for keeping track of an Ethernet interface
at intervals of 15 second, and I don't know how many rows to keep for
the 1 min, 5 min, 15 min, 1 hour, and 1 day averages I am keeping.

Would someone please explain to me how to pick a proper amount of rows
for an archive


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:? \
