Priority Rules

优先级规则

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`

优先级	规则	影响程度	工具
1	使用metrics前先检查metrics-server	严重	`get_resource_metrics`
2	部署前执行健康检查	高	`cluster_health_check`
3	发布前对比预发布环境与生产环境	中	`compare_namespaces`
4	记录基准指标数据	低	`get_nodes_summary`
