How do I find average CPU usage on Linux?

CPU Utilization is calculated using the ‘top’ command.

1. CPU Utilization = 100 – idle time.
2. CPU Utilization = ( 100 – 93.1 ) = 6.9\%
3. CPU Utilization = 100 – idle_time – steal_time.

How can I see how much memory a process is using?

Processes have private memory to hold their stack space, heap, and data areas. The only way to see how much memory a process is actively using is to use above command. This command is available in Solaris 2.6 and later releases. 1. NMUPM utility (Oracle Support)

How does SAR measure cumulative activity in the operating system?

In the first instance, sar samples cumulative activity counters in the operating system at n intervals of t seconds, where t should be 5 or greater. If t is specified with more than one option, all headers are printed together and the output may be difficult to read. -u 12 5: Comparison of CPU utilization; 12 seconds apart; 5 times.
