Cluster Health Check

Steps

1. Node status

   cluster_status: (no args for full cluster)
   

2. Check for warnings

   oc get events -A --field-selector type=Warning --sort-by='.lastTimestamp'
   

3. Check cluster operators (OpenShift only)

   oc get clusteroperators
   oc get co -o jsonpath='{range .items[?(@.status.conditions[?(@.type=="Available")].status!="True")]}{.metadata.name}{"\n"}{end}'
   

4. Check alerts (if monitoring stack available)

   oc get alerts -n openshift-monitoring
   

5. Resource capacity

   oc top nodes
   oc get pods -A --field-selector=status.phase!=Running,status.phase!=Succeeded
   

6. Summarize health

   • 🟢 Healthy — all nodes ready, no critical alerts
   • 🟡 Warning — degraded operators or resource pressure
   • 🔴 Critical — nodes down, pods failing, alerts firing
