Answer / c. anthony francis
Sar – system activity reporter
In the first instance, the sar utility 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 can be difficultto read. If
the –o options is specifeied, it saves the samples in
filename in binary format. The default value of n is 1.
In the second instance, no sampling interval is specidied.
Sar extracts data from a previously recorded filename,
either the one specified by the –f option or, by deafault,
the standard system activity daily data
file /var/adm/sa/sad for the current day dd.
Example:- sar –o temp 10 5
Binary read sar –f temp
