v0.49.1 arm64 - Error while reading product_name: open /sys/class/dmi/id/product_name: no such file or directory

[Chippi]

Upon upgrading from version 47.2 to 0.49.1, the following lines are repeatedly logged every 5 minutes:

I just noticed the same on RPi4 - any solution to this?

[stijn2911]

I'm also having the same problem. path /sys/class/dmi/ does not seem to exist on my rpi4. Does this have to do with ARM architecture?

[100kimch]

Mine too. same logs are shown in jetson nano.

[dzonder]

I'm seeing the same on RPi devices. Any way to de-verbose this? It's causing a lot of churn in the logs.

Seems to stem from file utils/cloudinfo/gce/gce.go:

const (
    gceProductName = "/sys/class/dmi/id/product_name"
)

...

func (provider) IsActiveProvider() bool {
    data, err := os.ReadFile(gceProductName)
    if err != nil {
        klog.V(2).Infof("Error while reading product_name: %v", err)
        return false
    }
    return strings.Contains(string(data), google)
}

The following patch suppresses the log only if the file is not found:
