…0.18.0 kube-prometheus v0.18.0 is the only release supporting Kubernetes 1.36 (also supports 1.33-1.35). Regenerate the Grafana dashboards and Prometheus alert rules from the v0.18.0 manifests. Patch refreshes: - dashboard 001/002: the patch files carried stale charms/worker/k8s/src/... paths copied from k8s-operator, so they never applied in this repo. Regenerated against the v0.18.0 output with correct src/... paths; the juju-field cluster filters and the node-exporter job regex are now actually applied to the dashboards. - rules 001_core_alert_rules: upstream v0.18 split the *Down alerts, adding *InstanceUnreachable warning alerts (up == 0) and rewriting KubeletDown to a cluster-level expression that works in charmed environments. The patch now only rewrites the three remaining absent()-based alerts (KubeAPIDown, KubeSchedulerDown, KubeControllerManagerDown) to up == 0, since scrape targets are always present in charm deployments. The new upstream alerts are kept. Also fix update_alert_rules.py wiping the whole src/prometheus_alert_rules directory; it now only replaces the files it manages.
