10. 分析总结和建议 | Summary and Recommendations
关键发现 | Key Findings
- Top 内存占用 Pod: 请查看第 3 节的 Top 20 列表
- 可能存在内存泄漏: 请查看第 6 节的高重启次数 Pod
- 未设置内存限制: 请查看第 7 节的 Pod 列表，建议添加 limits
下一步行动 | Next Steps
- 查看详细分析文档:
docs/dev-ops/analysis/work01内存紧张问题分析.md - 根据报告识别内存占用大户
- 执行低风险清理操作（清理缓存、日志）
- 优化高内存占用 Pod 的资源配置
- 考虑迁移非关键 Pod 到其他节点
