// Some of the alerts are meant to fire if a critical failure of a
// node is imminent (e.g. the disk is about to run full). In a
// true “cloud native” setup, failures of a single node should be
// tolerated. Hence, even imminent failure of a single node is no
// reason to create a paging alert. However, in practice there are
// still many situations where operators like to get paged in time
// before a node runs out of disk space. nodeCriticalSeverity can
// be set to the desired severity for this kind of alerts. This
// can even be templated to depend on labels of the node, e.g. you
// could make this critical for traditional database masters but
// just a warning for K8s nodes.
