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
