[rrd-users] Memory usage on large RRAs

Hi,

I am monitoring ~700 nodes using rrdtool, each updating 7 databases on a
central server.

Does anybody have experience on writing DEFs and CDEFs to minimize memory
usage? At the time being I am unable to successfully plot a cumulative graph
of all nodes, as memory runs out.
