Verified the V4 version of the metrics and alerts on 4.7.0-0.nightly-2021-01-05-055003 on an OVN cluster on AWS available subnet metric correct for hostPrefix = 26|23|20 allocated subnet metric correct as number of machines increased and decreased alarms fired when 80% of the subnets were allocated exceeding the allocatable number of subnets results in an alarm with 100% allocated and the surplus nodes are stuck NotReady with this reason: Ready False Tue, 05 Jan 2021 20:34:18 +0000 Tue, 05 Jan 2021 20:33:07 +0000 KubeletNotReady runtime network not ready: NetworkReady=false reason:NetworkPluginNotReady message:Network plugin returns error: No CNI configuration file in /etc/kubernetes/ cni/net.d/.
