While OProfile can be used by developers to analyze application
performance, it can also be used by system administrators to perform
system analysis. For example:
Determine which applications and services are used the
most on a system — opreport can
be used to determine how much processor time an application or
service uses. If the system is used for multiple services but is
under performing, the services consuming the most processor time
can be moved to dedicated systems.
Determine processor usage — The
CPU_CLK_UNHALTED event can be
monitored to determine the processor load over a given period of
time. This data can then be used to determine if additional processors
or a faster processor might improve system performance.
