Read CPU Speed & Usage

General
1

Hi All,

I need some support reading CPU speed and usage cross platform, I can see that for OSX and Linux using MBS plugins I can get the CPU speed but unable to read its usage,

Does anyone have any pointers they can give me for finding this information out about the clients machine?

Many thanks in advance,
Steve

By usage, you mean the percentage used of each processor at any given moment?

Yes please, or exact Mhz either.

System_profiler (Mac only) will show you an entire truck load of information, amongst which you find here :

There is an example included with Xojo that shows you how to get the CPU usage (using a Declare) on Windows:

Examples/Platform-Specific/Windows/CPUUsage

8

For Linux system information including CPU characteristics

cat /proc/cpuinfo
9

Thank you everyone for your support I will let you know how I get on,

How can I then take only the info I require from a CAT command?

Cheers,

Hi Christian,

How can I work out Mhz and used Mhz of the processor with http://www.monkeybreadsoftware.net/class-darwinvmstatisticsmbs.shtm

Cheers

Use the shell.result property and parse it.

I’m also trying to read the CPU useage on the three platforms. I think this thread is uncomplete, thus I think it would be a good idea to complete it.
Currently, the Windows version works, with the example included.
For Linux, the cat /proc/cpuinfo command returns useful data about the CPU (brand, speed, etc.) but nothing about the current percentage of CPU used.
On the Mac, the DarwinVMStatisticsMBS class seems to return useful information, but the documentation just states to calculate deltas like in the example; yet, I fail to find the example file (the one about DarwinVMStatistics lacks the CPU ticks field).

It would be nice to have a definitive answer to read CPU useage.

I’m also trying to read the CPU useage on the three platforms. For the sake of completeness, here’s what I’ve found:

On the Mac, the DarwinVMStatisticsMBS class is one way to go, assuming you have purchased the plugin. An example can be found in /MacOSX/CPU load info.xojo_binary_project.

The Windows version, already mentioned in this thread, works fine, with the example included with Xojo.

For Linux, the cat /proc/cpuinfo command returns useful data about the CPU (brand, speed, etc.) but nothing ovious about the current percentage of CPU used. However, this command does that:
“grep 'cpu ’ /proc/stat | awk ‘{usage=($2+$4)*100/($2+$4+$5)} END {print usage}’”
