To get this graph,

  • collect all system data, in this example for 20 intervals lasting 1 second each, using the data file /tmp/sar.out:
sar -o /tmp/sar.out 1 20
  • convert the binary data to a human-readable format. -A stands for "all".
export LC_ALL=C; sar -A -f /tmp/sar.out >/tmp/sar.out.txt
java -jar kSar.jar -input /tmp/sar.out.txt
