The alerting is provided by two separate graphs from the health graph so that actual health state is logged regardless of alerting. The `ceph_utilization` plugin provides no configuration; only the cluster utilization graph alerts such that >80% used is warning and >90% used is critical. Ceph itself begins warning above 80% as well.
