A while ago someone posted a link to some mrtg/iptraff type gifs showing
the cpu/disk/IO for 4 identical real-servers for several hours. The graphs
for the real-servers were indistinguishable.
What are you going to do if you find that (say) disk activity is too high
on one real-server? All other real-servers are going to be having equally
busy disks.
