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.
