Best way to detect and terminate high cpu usage?

[SoWhy]

Hi all,

I have a PVE with 20 Windows 11 Pro guests. All are configured the same. There is one application running that users need and that cannot be replaced but which also is a piece of crappy coding which will regularly start using high amounts of cpu without discernable reason, forcing me to kill and restart it. I would like to automate this process but I'm not sure if it's easier to have Proxmox monitor the usage and issue a command using the guest agent or whether I should install something on the guests to monitor and take action. I know that there is likely always the same culprit, so I don't need anything that determines which process is causing the high cpu, I just need to determine that high cpu usage is happening and act accordingly.

Apart from proxmox, I also have Remotely installed on the guests to execute commands. I can also install something on the guests directly or install another software to remotely monitor and execute commands.

So what would be the best solution for this type of problem?

TIA

you can monitor usage (e.g., by calling the VM status API endpoint) and execute commands inside the VM (if the guest agent is installed). but you'll have to write the code glueing that together yourself
