Kubernetes Diagnostics
Analyze cluster health and compare resources using kubectl-mcp-server's diagnostic tools.
When to Apply
Use this skill when:
-
User mentions: "metrics", "health check", "compare", "analysis", "capacity"
-
Operations: cluster health assessment, environment comparison, resource analysis
-
Keywords: "how much", "usage", "difference between", "capacity planning"
Priority Rules
Priority Rule Impact Tools
1 Check metrics-server before using metrics CRITICAL get_resource_metrics
2 Run health check before deployments HIGH cluster_health_check
3 Compare staging vs prod before release MEDIUM compare_namespaces
4 Document baseline metrics LOW get_nodes_summary
Quick Reference
Task Tool Example
Cluster health cluster_health_check
cluster_health_check()
Pod metrics get_resource_metrics
get_resource_metrics(namespace)
Node summary get_nodes_summary
get_nodes_summary()
Compare envs compare_namespaces
compare_namespaces(ns1, ns2, type)
List CRDs list_crds
list_crds()
Resource Metrics
get_resource_metrics(namespace="default")
get_node_metrics()
get_top_pods(namespace="default", sort_by="cpu")
get_top_pods(namespace="default", sort_by="memory")
Cluster Health Check
cluster_health_check()
get_cluster_info()
Compare Environments
compare_namespaces( namespace1="staging", namespace2="production", resource_type="deployment" )
compare_namespaces( namespace1="default", namespace2="default", resource_type="deployment", context1="staging-cluster", context2="prod-cluster" )
API Discovery
get_api_versions()
check_crd_exists(crd_name="certificates.cert-manager.io")
list_crds()
Resource Analysis
get_nodes_summary()
kubeconfig_view()
list_contexts_tool()
Diagnostic Workflows
Cluster Overview
cluster_health_check() get_nodes_summary() get_events(namespace="") list_crds()
Pre-deployment Check
get_resource_metrics(namespace="production") get_nodes_summary() compare_namespaces(namespace1="staging", namespace2="prod", resource_type="deployment")
Post-incident Analysis
get_events(namespace) get_pod_logs(name, namespace, previous=True) get_resource_metrics(namespace) describe_node(name)
