Anyone know how using applescript to get the CPU level, and free/consumed ram?

I know there is some shell integration in AppleScript, but have failed to do this successfully yet.

Call this as a shell script and it will get what you want. It should be easy to parse the string that it prints out from within Applescript.

Don't forget that in Applescript, you'll need to escape the quotes with \" and \':

Code:
top -l 1 1 | awk '/CPU usage/ {printf("user\t%s\nsys\t%s\nidle\t%s\n",$8,$10,$12)} /PhysMem/ {printf("wired\t%s\nactive\t%s\ninactive\t%s\nused\t%s\nfree\t%s\n",$2,$4, $6, $8, $10, $12)}'

You can try pasting it into the Terminal to see how it works. It just takes the output from top and feeds it through awk, which is a very handy tool for extracting text.

You can use the Standard Additions' "system attribute" event.

It is a wrapper to Gestalt. which will allow you to get all sorts of info about the machine.

e.g.

Code:
get system attribute "cput"

then (if you have the Dev tools) look through gestalt.h for the return values. here's a bit:

/*
The gestaltNativeCPUtype ('cput') selector can be used to determine the
native CPU type for all Macs running System 7.5 or later.

The 'cput' selector is not available when running System 7.0 (or earlier)
on most 68K machines. If 'cput' is not available, then the 'proc' selector
should be used to determine the processor type.

An application should always try the 'cput' selector first. This is because,
on PowerPC machines, the 'proc' selector will reflect the CPU type of the
emulator's "virtual processor" rather than the native CPU type.

The values specified below are accurate. Prior versions of the Gestalt
interface file contained values that were off by one.

The Quadra 840AV and the Quadra 660AV contain a bug in the ROM code that
causes the 'cput' selector to respond with the value 5. This behavior
occurs only when running System 7.1. System 7.5 fixes the bug by replacing
the faulty 'cput' selector function with the correct one.

The gestaltNativeCPUfamily ('cpuf') selector can be used to determine the
general family the native CPU is in. This can be helpful for determing how
blitters and things should be written. In general, it is smarter to use this
selector (when available) than gestaltNativeCPUtype since newer processors
in the same family can be handled without revising your code.

gestaltNativeCPUfamily uses the same results as gestaltNativeCPUtype, but
will only return certain CPU values.

I didn't think most gestalts worked in OS X?

Most of the important ones do.

More importantly - I just re-read the original post - and realised that I completely mis-read it first time round - You want the workload - not the proc type - Doh!

ultimately I want

x = processor concumption
y = free ram
z = used ram

Code:
x = top -l1 | grep "CPU usage" | awk '{print $8}'
y = top -l1 | grep "PhysMem" | awk '{print $10}'
z = top -l1 | grep "PhysMem" | awk '{print $8}'

You can wrap shell commands pretty easily and get what you want.

Too bad OSX doesn't have a /proc/cpuinfo like Linux.

[int69h]

It's /proc/cpuinfo, but it doesn't contain that sort of information anyways. It contains information about the physical chip.

A combination /proc/loadavg and /proc/meminfo would give you the info you need.
