[rrd-users] RRD Archiving (AVERAGE,MIN,MAX,LAST)

[nate]

Hello!

I am trying to define some RRA archives for some new stats I hope
to start collecting and am wondering if what I am doing is redundant:

rrdtool create filename.rrd --step 300 DS:idle:GAUGE:600:0:100
RRA:LAST:0.5:1:200000 RRA:MIN:0.5:1:200000 RRA:MAX:0.5:1:200000
RRA:AVERAGE:0.5:1:200000

I am interested in storing every data point collected for the
200000 cycles, would just making an archive with LAST be sufficient:

rrdtool create filename.rrd --step 300 DS:some_name:GAUGE:600:0:100
RRA:LAST:0.5:1:200000

or do I also need archives for MIN MAX and AVERAGE as well? Will
RRD not be able to calculate averages if I only store the raw data
points?

thanks!

nate
