Can a VI monitor its own memory usage, as in the "Windows Task Manager"?

[bmihura]

I'm in Windows XP, and want to monitor LabVIEW's memory usage number seen in the "Mem Usage" column of the "Processes" tab of "Windows Task Manager".

Opena VI reference to the VI in question and look for the properties in the "metrics" section.

Of course the task manager does not report memory on a VI basis, just the entire LabVIEW process, so you most likely won't get the same numbers.

Open the example finder. There is also a shipping example called "Memory Monitor". Use it directly or look at the code for ideas. 😄

I'm trying to catch memory leaks that LabVIEW wouldn't be aware of, like forgetting to close an open reference.

I'll bet there's a way to get that "Windows Task Manager" number, such as a .NET framework call, but I can't find it.

OK, open the exmaple finder, search for keyword ".NET" and have a look at the example:

"Simple process monitor". It uses .net to get all you possibly want. 😄

Thanks

That is exactly what I was looking for.

--- For the record, this does not work.  The help plainly states that "You cannot read this property if the VI is running".

That means that a VI cannot monitor itself (or it's children).

If you try, you get 0 and an error ("The VI is not in a state compatible with this operation").
