The following are demonstrations of the runocc.d script.
Here we run it on a single CPU server that is fairly busy,
# ./runocc.d
CPU %runocc
0 86
CPU %runocc
0 85
CPU %runocc
0 82
^C
The run queue occupancy is around 85%, meaning most of the time there
are runnable threads queued waiting for CPU.
This script is more interesting on a multi-CPU server,
# ./runocc.d
CPU %runocc
1 16
3 27
0 38
2 75
CPU %runocc
0 25
2 41
3 42
1 50
CPU %runocc
3 1
0 17
2 26
1 27
CPU %runocc
3 2
2 5
0 24
1 25
^C
Here there was some degree of saturation, especially on CPU 2 to start with.
