My shell script:
----
./rrdtool create test2.rrd \
--start now --step=5 \
DS:ok:GAUGE:10:0:100 \
RRA:LAST:0:1:10
for i in 2 20 4 40 6 60 8 80 10 100
do
sleep 5
./rrdtool update test2.rrd -t ok N:$i
echo "Updated DS \"ok\" with value $i"
done
./rrdtool dump test2.rrd
----
Wen I run my script it output this:
Updated DS "ok" with value 2
Updated DS "ok" with value 20
Updated DS "ok" with value 4
Updated DS "ok" with value 40
Updated DS "ok" with value 6
Updated DS "ok" with value 60
Updated DS "ok" with value 8
Updated DS "ok" with value 80
Updated DS "ok" with value 10
Updated DS "ok" with value 100

Questions
1. Is there a way to get the values I add to show up unaltered in the RRA?
Tried with LAST, AVERAGE, MIN and MAX in the RRA declaration.
2. How are the values in my RRA calculated?
