Want a good fedora profiler
 

Can anyone suggest me a good linux profiler for my proj work.. Some good one whose parameters can be extracted through scipts..

What exactly is your purpose? Just googling gives Oprofile and Sysprof that seem to be what you need. But I have used none of those.

I have to monitor CPU usage for load balancing in virtualized environment.. Can the output of those profilers be extracted using scripts??

I already said I have not used any of those. For cpu usage I usually use top command that gives me real time usage of cpu.

though the top command displays the cpu usage, i want some profiler which monitors various system parameters periodically say every 5 min and provides it as an input to a script..this will help me balance the load on either a virtual or physical machine..

But why do you want to manipulate the cpu usage of a system? Anyhow, if you still want to do that you can try one of those profilers.

actually im supposed to balance the load of a virtualized network. Shud start or stop the virtual machines according to the load of the physical machine. In such a case monitoring of CPU usage periodically is mandatory.

In that case you are just monitoring the cpu usage and not manipulating it.
