I have a Rocky OpenStack cluster that I want to monitor the memory usage of instances.
monitoring Linux instances is OK but Windows Server instances do not provide any data for memory usage.
I've searched a lot, and I've installed the balloon driver on Windows instances but it did not work for me. All components are updated to the latest version.
So, how can I get memory usage data from them?
You must be Install the Virtio Balloon driver AND the Balloon service in the guest:
1-Open Device Manager and see if there is an unknown PCI device. If so, right click it and install the driver manually from D:\Balloon\2K16\amd64 (or 2k12, 2k8, etc)
2-Now copy the entire amd64 folder into C:\Program Files\ and rename it "Balloon". So, now you have the amd64 folder from the disc copied as C:\Program Files\Balloon
3-Open an Administrative Command Prompt and cd to C:\Program Files\Balloon
4-Run this command:
