[rrd-users] Storimg 5 min data for 2 yr

[Andrew Werbowy]

I got request to store 5 min MRTG data for 2 yr. I know what it is not possible with MRTG, so I will have to use RRDTools. I read basic stuff about RRD and looks like I would have to do something like this:
 rrdtool create myrouter.rrd         \
            DS:input:COUNTER:600:U:U   \
            DS:output:COUNTER:600:U:U  \
            RRA:AVERAGE:0.5:1:210240     \
            RRA:AVERAGE:0.5:6:700      \
            RRA:AVERAGE:0.5:24:775     \
            RRA:AVERAGE:0.5:288:797    \
            RRA:MAX:0.5:1:210240          \
            RRA:MAX:0.5:6:700          \
            RRA:MAX:0.5:24:775         \
            RRA:MAX:0.5:288:797
note 210240 which is 2 year of 5 min stats (I think). Database would be 6.8 meg big per switch/router/server interface.
What are best practices in such cases?
 
Regards,
Andrew
