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"
)
