Produce and deliver reports on system utilization (processor, memory, disk, and network)

This is a relatively easy objective. You need to use the sar command. This command has a large number of flags that can be combined. If you want to get everything, hopefully you won't have to analyse it :), just use:

sar -A

In order to get processor utilization statistics use simply use (note that cpunumber is zero based, in other words the first cpu is 0) :

sar
or
sar -P cpunumber
or
sar -u ALL

In order to get memory usage statistics, use:

sar -rR

To get swap usage statistics, use:

sar -S

Arguably paging usage statistics are part of the memory, so:

sar -B

You can get disk usage statistics with:

sar -b
or
sar -d
or even
sar -dp

Finally network usage statistics can be obtained with (note that there are over 15 different keyworks, e.g. ICMP, EICMP,TCP, ETCP etc, and you can normally add an E to the keyword to get the error statistics):

sar -n DEV
and
sar -n EDEV

Unfortunately, the manual page is very long and unwieldy, so it might be a good idea to remember some of these by heart for the exam.
