Subject: [PATCH 8/8] tools/vm/slabinfo: gnuplot slabifo extended stat
GNUplot `slabinfo -X' stats, collected, for example, using the
following command:
while [ 1 ]; do slabinfo -X >> stats; sleep 1; done
`slabinfo-gnuplot.sh stats' pre-processes collected records
and generate graphs (totals, slabs sorted by size, slabs
sorted by size).
Graphs can be [individually] regenerate with different samples
range and graph width-heigh (-r %d,%d and -s %d,%d options).
To visually compare N `totals' graphs:
slabinfo-gnuplot.sh -t FILE1-totals FILE2-totals ... FILEN-totals
