I am searching for an element that will permit me to determine a present status of php scripts running and showing me just how much memory/io/cpu they're consuming at this time.

I've got a wordpress website that includes a lot of plug ins set up in it, and I am presently getting performance problems that I suspect are based on one of the numerous plug ins.

I am searching for a fast method to check which script/wordpress plugin is consuming probably the most IO/memory/cpu.

You are able to install the Xdebug extension and employ its profiling functions. The profile will highlight the length of time is put in each function so you'll most likely have the ability to discover the Wordpress wordpress plugin that consumes a lot time.

I am afraid there's no such command or utility that actually works 'natively' within PHP.

Because you have labeled Apache, please take a look to Apache's Status module: http://httpd.apache.org/docs/2.0/mod/mod_status.html

The output goes like http://www.apache.org/server-status

This obviously requires you to definitely have root use of your webserver, however i accept is as true shows useful informations. This could demonstrate, which Web addresses take most CPU time. To research further you may need a profiler like (pointed out) Xdebug.
