**Cluster Health Check** (`scripts/cluster_healthcheck.sh`):
- **ALWAYS use this script** to check cluster health — whether the user asks explicitly, after deploying/updating services, or whenever you need to verify cluster state. Never use ad-hoc kubectl commands to assess overall cluster health; use the script instead.
- Runs 14 checks: nodes, resources, conditions, pods, evicted, DaemonSets, deployments, PVCs, HPAs, CronJobs, CrowdSec, ingress, Prometheus alerts, Uptime Kuma
- Runs 24 checks: nodes, resources, conditions, pods, evicted, DaemonSets, deployments, PVCs, HPAs, CronJobs, CrowdSec, ingress, Prometheus alerts, Uptime Kuma, ResourceQuota pressure, StatefulSets, node disk, Helm releases, Kyverno, NFS, DNS, TLS certs, GPU, Cloudflare tunnel
- **When adding new healthchecks or monitoring**: Always update this script to validate the new component
