Get Webview2 Process ID?

[KiddoV]

So Wails generate some webview2 processes. I make an app that has a tracking feature to track for memory and cpu usage (in percentage, specifically).
Right now, I can get the process of my app easily with os.Getpid(), and get those info using gopsutil. The thing is, if Wails has another processes such as webview2 associated with my app that running separately, the information that I get right now will not be accurate since webview2 is from a different process.
The question is, how do I get the webview2 pid associated with my Wails app, so I can get the exact total of memory and cpu usage?

You need to incorporate the parent process id of the processes and use the process tree. All WebView2 processes have a parent process and will finally root into the Wails pid. This could be over several levels of processes, e.g. WebView2 -> WebView2 -> Wails.

AFAIK gopsutil returns the parent process id, so you should be able to loop over all processes and find those which are connected the the wails process.

Please try to use Process Explorer from the SysInternals Tools to view the process tree. What do you see there?

I don't have that tool on my PC, can you provide the link to download it?

Have you tried just starting the production build without wails dev? I currently wasn't able to see your behaviour, at least not with a production build and on Windows 11.

Have you tried just starting the production build without wails dev?

You meant to build and run on exe file? I thought wails dev will build and run on my-app-dev.exe anyway? Is it not the same thing?

Yeah build and run, maybe there's some difference. I don't know...

@stffabi Yes, you are right, it groups all the processes within .exe file, not in the dev mode.

Thank you!
