 Ok... i MUST CHANGE ALL!!!!!

 But i am too confussed now to know/calculate the values.

 Can you help me with this????

 If i want to make this kind of graphs:

 graph of 1 hour (last one) 
 graph of 2 hours (last one) 
 graph of 1 day (last one) 
 graph of 1 week (last one) 
 graph of 1 month (last one) 
 graph of 1 year (last one)
 graph of 2 years (last ones)
 graph of 1 year (1 year ago)
 graph of 1 year (2 year ago)
 graph of 1 year (3 year ago)
 graph of 1 year (4 year ago)
 graph of 1 year (5 year ago)

 these graphs are about:
  servers: swap, ram, processes, ethernet, partitions, cpus, ...
  switchs: ports, ...


Now i have the following 
(all rrd files have the same values in step, heartbeat and RRA,
 DS has diferent names and DST is diferent for Ethernet):

rrdtool create XXXX.rrd --step 60 \
  DS:in:GAUGE:600:U:U             \
  DS:out:GAUGE:600:U:U            \
  RRA:AVERAGE:0.5:1:600           \
  RRA:AVERAGE:0.5:6:700           \
  RRA:AVERAGE:0.5:24:775          \
  RRA:AVERAGE:0.5:288:3725        \
  RRA:MAX:0.5:1:1:600             \
  RRA:MAX:0.5:6:700               \
  RRA:MAX:0.5:24:775              \
  RRA:MAX:0.5:288:3725




 The IMPORTANT questions (with the information above):

 * how many RRAs and with which values must i use???

 * What hearbeat and step values are the correct????

 NOTA: i get data each minute.



 Thanks in advance.......
