cpu value returns zero

[Paul-Reed]

Hi, I'm using your library on a Oracle Cloud VM.Standard.A1.Flex server, with Canonical-Ubuntu-22.04 OS.
Unfortunately, it does not return the "cpu" value, and for every child process the result is "cpu":0.
There are no errors in the logfile and the other metrics appear to display correctly.

Is this a known compatibility issue?

Hi, I am having a similar issue.

Originally I mentioned the issue on a module that uses your library:
bartbutenaers/node-red-contrib-process-resources#1 (comment)
Node Red for reference here: https://discourse.nodered.org/t/node-red-kept-restarting-upon-git-push/77181

The issue shows in my log like this:
3 Apr 08:06:09 - [red] Uncaught Exception:
3 Apr 08:06:09 - [error] TypeError: Cannot read properties of null (reading 'cpu')

https://github.com/bartbutenaers/node-red-contrib-process-resources put a workaround in place, but the author suggested that you check in your library.

Please let us know if you need more details.
