Programmatically monitor CPU usage

[soupy]

I have some processor intensive data acquisition and control programs that run on windows servers. Data integrity is extremely critical. I want to get all of the metrics I can to prove that data is good and determine how far away I am from "bad" data. Does anyone know a method to acquire the current CPU usage? A total usage will suffice, but levels for each core would be super awesome!

Thanks in advance,

-Andy

Are you looking for a third-party tool that monitors in the background, or do you want a http://zone.ni.com/devzone/cda/epd/p/id/4659' target="_blank">VI that will allow you to monitor it in your code?

Thanks, but it appears that eTree perfmon no longer exists on the internet. All the links for it are dead. Do you know of any web site that would still have it, or do you have it?

Take a look at the http://decibel.ni.com/content/docs/DOC-2051' target="_blank">Windows Performance Monitor that uses .NET calls to access CPU (including per core values) and other system parameters.

There is a similar VI for RT applications on NI's website.

I don't, but it looks like Nev's suggestion of the http://decibel.ni.com/content/docs/DOC-2051' target="_blank">Windows Performance Monitor is what you're after.

I prefer Process Lasso for monitoring as well as controlling applications.

Why use third party when you can do it in .NET?

Here is an example that you can modify to do what you want.

Awesome! This one is nice 'n easy.

Can you use .NET to query the processor usage of a program?

The Windows Performance Monitor I mentioned earlier, does EXACTLY that.

I'm sorry, I hadn't had time to fully investigate that VI yet. You are correct, it does exactly that (and more!). I'll make a VI just for processor usage and post it shortly.

Thanks all for the help!

Yes. Just modify the example, changing 'Private Bytes' to the proper counter name you want.

Good luck finding it! Microsoft makes this so incredibly hard to understand and find in MSDN that you will want to scream :headbang:

Try looking here for starters:

Here is a VI that monitors all CPU usage. You might be able to modifiy this to give you the % of a specific process.
