Run nmon

nmon has one important parameter which decides how often the screen is updated. The default is quite slow but if you hit space-bar it will update immediately. To set the update rate to three seconds use the -s 3 parameter, as below:

nmon -s 3

Note: a one second refresh rate can take 10% of the machine's CPU which is not friendly unless you are the sole user of the machine.

There are other parameters (we don't use them much) which you can find out more about by typing:

nmon -h
