I would like to measure the processor utilization of my linux system. It is an embedded system with linux (2.4.18, non-preemptible) running on a MIPS processor. Basically it runs VoIP related stack (signaling + data).
I would like to measure how much is the processor utilization when a series of events occur. I know that we have a "top" command to see the load on a per second basis.I don't want a per second utilization but utilization under a given test scenario.
For an RTOS like system, we have techniques like running a low-priority task and a very high priority task and then estimating on the basis of how much time the low-priority task gets scheduled. This may not be of use because we are on a non-preemptible linux running processes without priorities.
Any techniques or ways of measuring in this scenario would be of help.
Thank you in advance.
