// Available disk space (%) thresholds on which to trigger the

// usage grows in a way that it is predicted to run out in 4h or 1d
// and if the provided thresholds have been reached right now.
// In some cases you'll want to adjust these, e.g. by default Kubernetes
// runs the image garbage collection when the disk usage reaches 85%
// of its available space. In that case, you'll want to reduce the
// critical threshold below to something like 14 or 15, otherwise
// the alert could fire under normal node usage.
